KIRIBATI 36

Green Nomad sails North

On the 15ht of November, 2011, finally our Green Nomad, now in its second form, a Kiribati 36, left port to start the life we allways long for, the jumps from anchorage to anchorage through the most diverse places in the world.

We left the port of Rio Grande, which is the southernmost sea port in Brazil, where we were so gently harboured by the Rio Grande Yacht Clube for one year and a month, after Clube dos Jangadeiros, in Porto Alegre, had also done the same, allowing us to finish building our boat while leaving on board. That comes to show that the hospitality of the yacht clubs in this area of Brazil is second to none.

Farewell party with friends from Rio Grande Yacht Club

We spent such a long period in Rio Grande due to the side trip we made to join the Sea Shepherd Conservation Society fleet in their environmental actions.

So, even though in between I had sailed more than 32500 nautical miles, after 5 years since the sale of our first Green Nomad in Australia, we were back at sea on our own boat.

It was a long and tortuous journey from one boat to the next, and building two boats for sure is not the most direct way to have your own cruising sailboat, but for us it is the best one, because it offers the liberty of choice of getting exactly what you aspire for, and the confidence of knowing exactly how everything has been put together, giving you a boat you can trust at a cost you can pay.

The life of a boatbuilder, especially of a boat dwelling boat builder, when you live inside what one day will be your boat, has its difficulties, but if not the most comfortable, for sure is the one that gives you the most fun, as instead of leaving in some provisional home and thinking that tomorrow morning you have to get out, drag yourself to a shed tucked away in some corner of the city and do some heavy work, you are already there. You work hard during the day, but at night you are right there, in the middle of a marina or yacht club, with the whole cruising scene unfolding before your eyes, and most of the times some social life with other boats starts. You are cruising already!

Guests for dinner, please sit anywhere you find suitable!

The time spent in Porto Alegre was one of hard work and little comfort, but life was going on normally, the boat was not a distant dream covered in dust, but a reality you lived on.

Even a yacht design office our unfinished Green Nomad was, with an improvised desk hanging off the ceiling.

In Rio Grande again we stopped for quite a long period, and in between the jobs we need to do before we set out on Green Nomad’s first open ocean trip, I developed and completed the latest design to be launched by B & G Yacht Design, the Pop Alu 32. In this period I also joined a ship to go to Antarctica and delivered another one from Tahiti to France.

We wanted to leave Rio Grande with the best possible forecast, as this part of the South American coast can be very treacherous, because for more than 280 Nautical Miles there is nowhere to seek shelter, and the prevailing winds are directly against the route North. A change to a Northeast wind can drive you right back to Rio Grande, or a change to strong Southeasterlies can pin you against the coast , with headwinds both ways. Any problem with the boat in this moment can mean ending on the surf.

So we took our time, and finally an uncommon but very favourable weather forecast came. The winds on this coast at this time of the year are predominantly from the Northeast, right on the nose if you want to sail to Santa Catarina state, and usually the strategy is to wait for a cold front associated with a low pressure system travelling East down South in Patagonia. This usually interrupts the Northeasterly flow and brings moderate to strong South and Southwestery winds, many times with rain and bad visibility.

What we got was different, a low coming out of the coast of Brazil, from Rio de Janeiro and heading offshore on a Southerly course, and this situation brought Southeast and then South winds of moderate intensity with nice clear skies. We were lucky and the good weather followed us all the way through, motor sailing and sailing at 7 knots sometimes.

From 1 to 5, the low that brought Green Nomad North

To keep tabs on the weather we used GRIB files, that you can download from the internet ( see link on Green Nomad’s website ). We could get updates on the way by using our HF data modem.

After we passed Cabo de Santa Marta, the most critical part of the journey was behind us, and we could step back and shut the engine down. We spent the last afternoon and night sailing in very light and variable winds, so weak I had trouble seeing where they were blowing from at times, and Green Nomad was still moving at speeds from 3 to 5 knots.

We sailed at a good distance from shore, 30 miles at times, in order to minimize the risk of running over fishing nets and long lines, and to our luck the plan worked. The drawback was being almost on the merchant ship lane, but these were easy to spot and avoid in such good weather.

At times we were hearing Brazilian Air Force aircraft calling ships by their names, and we assumed rightly that it was some sort of ship traffic control, and so our own time came, a low flying dual prop aircraft made three passes around us, called us on VHF channel 16 and after some routine questions wished us a good trip and left.

We knew of such strict control when you approach Australia by sea, but the curious fact is that we sailed into Australian waters twice and were never controlled, and now in Brazil it came to pass.

In the morning of the 18th we approached Porto Belo, in Santa Catarina State, 402 Nautical Miles away from Rio Grande, and the first sea leg on Green Nomad was coming to an end, with the boat having preformed even better than we thought and expected. The sea berths proved to be on a very good spot, with minimal movement being close to the boat’s pitch and roll center, and the airy and bright interior made cooking and checking the chart a pleasant task, with a view to the outside at all times.

On arrival we were met by our good friend João Blauth, who lives aboard his sailing home Zuretta. João was my crewmember when I delivered a 33 m trimaran from Tahiti to France.

We took the opportunity to get in touch with long time crusing companions Vilmar Braz and Gina, with whom we sailed across the Pacific in 1998.

Vilmar and Gina sailed around the world in their Samoa 29, a capable cruising sailboat also built to B & G Yacht Design plans ( not in the current design range anymore), and have now moved back to land, where they are doing a great job by creating and directing a sailing association that aims to teach sailing, seamanship and boatbuilding skills to kids from poor neigborhoods around their hometown of Itajaí, also in Santa Catarina State, 15 miles up the coast from Porto Belo.

This is how we are back doing what we most love, surroundend by friends in our almost autonomous home, generating our own electricity and collecting rain water. A good life with minimal environmental impact.


Kiribati 36 Green Nomad. A business meeting aboard

On December, 13, 2011, the member of B & G Yacht Design, Roberto Barros, finally managed to pay a visit to Green Nomad. The boat had been built in the southernmost Brazilian state, Rio Grande do Sul, so it was easier for him to wait for the scheduled call of Green Nomad at Parati, State of Rio de Janeiro, as he runs the local branch of the office in Rio. Six months earlier, during a holiday, Luis Gouveia had flown from Korea, where he is working temporarily, to Rio Grande do Sul, Brazil, to visit the then just launched Green Nomad.  Now Roberto Barros took with him the designer Murilo Almeida, another member of the company's staff, to be introduced to this new boat of our line of stock plans, and take advantage of this opportunity for meeting Luis Pinho, the co-designer of the Kiribati 36 project, and also an associate in the yacht design office, since they didn't happen to be acquainted to each other yet.

The meeting took place in one of the most beautiful cruising grounds you can find anywhere, Parati Cove, Ilha Grande Bay. We know that Green Nomad is expected to be visiting soon many other cruising paradises, however there is no doubt that her skipper started with the right foot, choosing this nook with such gorgeous landscape. Luis and Marli intend to stay in the Ilha Grande surroundings until the end of summer, and then depart for the Caribbean, Panamá and the South Pacific, having Australia, the country of Luis citizenship, as their final destination

The story of this thirty-six foot aluminium cruising sailboat is a long one. Luis had already  built another thirty-six footer, a fixed keel monohull that took him and his wife to the most distant corners of the South Pacific, a choice that obliged the couple to endure the hurricane seasons finding shelter in places less appropriate to stay in such occasions due to the deep draught of their boat's keel. Tired of seeing the shallower yachts having the best spots for themselves in the hurricane holes they aimed for shelter, Luis decided to sell his boat in Australia, and fly to Brazil, his wife's country, to build his swing-keel dreamed boat, which he co-designed with the office, the Kiribati 36 Green Nomad. Being a metallurgic engineer, Luis wanted to participate as welding supervisor in the construction of the metallic work of his boat, what he managed to do, and from then on made the rest of the construction himself, with the only assistance of Marli. With such large experience on his shoulders, he knew exactly what he wanted, obtaining a very functional yacht, the boat the couple intend to live aboard from now on. After having already sailed nine-hundred miles on the new boat's maiden voyage, the couple is feeling again as fish in their element. You can learn more about the couple's adventures, opening the banner on the left upper-corner of our home-page – Green Nomad. There you will find a collection of articles about their previous adventures, from the atolls of Micronesia to sub- Antarctic waters, when Luis took part in the 2010 Sea Shepherd environmental expedition aboard the whale protector ship Steve Irwin.      

Marli setting the table for the fraternization lunch with the other two members of B & G design team. The feeling of spaciousness of the saloon is outstanding. It must be very gratifying to live aboard such a functional sailboat.

What impressed most the two guests was the excellent natural illumination of the interior of the boat, as well as the sensation of airiness experienced inside the saloon. The hatches installed in the side-walls of the cabin trunk made a perfect integration with the outside, a feeling that can't be matched by other yachts where the social area of the boat is installed deep inside. The raised floor in the galley and navigation quarters enhances this sensation of sharing life aboard with the outside elements

Luis and Marli came to be acquainted with the designer Murilo Almeida in this very occasion. The possibility of joining a team from different places working together to produce yacht designs is one of the miracles of the new century. The rotating seat in front of the navigation table, where Murilo is seated, is Luis's “office” seat, where he developed our latest design, the Pop Alu 32

Luis and Marli are so accustomed with their sea gipsy life-style, that no matter where they call with Green Nomad,  they become the hub of the cruising community, their boat being constantly visited by other cruising sailors. It is not by coincidence that they have friends from all over the world


Kiribati 36, one more unit being built

This weekend we received a visit from Jone and Vera, a couple that elected the Kiribati 36 design as their dream boat and are having one built in Porto Alegre, southern Brazil, at Ilha Sul Construções Náuticas boatyard.

Vera and Jone visit Green Nomad in Rio Grande

Jone has been in contact with us for a long time, and seeing the first sections go up in the yard was a great joy for them and us too, as our design gets one more unit in the water.

The CNC cutting files kit for the Kiribati 36 was all revised and improved after the building of the prototype, Green Nomad, and we can say that some solutions adopted and some changes, like making the topsides top plate advancing above the deck and making an integrated toe rail introduced even more productivity gains for the builders.

The time needed to complete the metal work is very much shortened with the use of pre-cut kits, and the precision and quality of the assembly is generally better than what can be achieved with the traditional lofting method.

All transversal structure sections were assembled in the first week, and we can already see the boat taking shape.

The boat size, 11 meters or 36 feet, falls in the frontier between small and big boats. It is still not too expensive to build and is easy to handle, but its size allows a practically unlimited range, with enough load carrying capability for long expeditions

Its extra heavily built hull, with 10mm in the bottom and 8mm sides is suited to the harshest navigation conditions, from tropical depressions to polar expeditions, making the Kiribati 36 a viable option for adventurers with great inspiration but short in funds.

The hull of the Kiribati 36 is stronger than the one on this ship!

The design opts for simple solutions for the essential systems on board, and this means that once built, the future running costs should be limited. Being an aluminum boat also is a plus concerning maintenance costs.

A simple boat, with tiller steering and robust systems

For those who like the design but feel they do not need shallow draft, the news is that it is almost finished the version of the design with a conventional fixed box keel. This in turn should be even more economical to build. The benefits of shallow draft accessibility come at a cost, and for sailors that do not require a boat that can reach spots only 80 cm deep but likes the other aspects and solutions of this design, there is now one more option in B & G Yacht Design´s range.

Kiribati 36 can also be built with a fixed keel


Kiribati 36 Green Nomad maiden trip.

After 30 months of boat building we finally got under way yesterday, leaving Porto Alegre towards the city of Rio Grande, where Lagoa dos Patos meets the South Atlantic Ocean.

Celebrating the first sundowner at anchor

This huge body of fresh water extends for 120 nautical miles from the mouth of the Guaiba Lake to the breakwaters in Rio Grande.

We will be taking easy and exploring the anchorages on the way. We are now anchored waiting for the passage of a coming front that will bring head winds from SW, and after it, we will move another step.

Luis feeling his boat's rudder control for the first time under sail. The lifting swing keel and the shallow draught twin rudders allowed a much more pleasurable trip to Marli and Luis, allowing them to enter in shallow waters denied to fixed keel sailboats

The news is that we tried our sails for the first time, even though we haven't the cockpit winches installed yet. We are sailing towards Tapes, in a close reach with a speed of seven knots, feeling no weather helm so far, the boat making a straight course.

We are very pleased with Green Nomad's performance, especially when we remember that the main sail is just a given one from a larger boat that we had to cut to fit the Kiribati 36 sail plan.


Virtual step by step slide show from the assembly of a Kiribati 36 metal work will help builders

Taking advantage that the Kiribati 36 design was created using state of the art 3D computer modeling, B&G Yacht Design is making available a step by step virtual slide show from the assembly of a Kiribati 36 metal work, with the parts added in the suggested order.

This will come to help possible builders to evaluate the magnitude of the task at hand and help them decide if this Project is for them.

In another fact related to this design, it is already in progress the development of a fixed keel version, which will make use of the already proven appendages that are found in the Multichine 34/36 series.

Green Nomad has its rig now

This will confer to the design a more universal appeal, with it becoming available to a range of sailors that do not need extra low draft and prefer the simplicity and lower building costs of a fixed keel boat.

Green Nomad´s interior nearly complete

The concepts of simple systems, ruggedness, panoramic view from inside the cabin and several others linked to the Kiribati 36 appeal to a big range of sailors, and the incorporation of a fixed keel version will be a great plus for the design.


Kiribati 36 Green Nomad nears interior fit out completion

Summer is slowly arriving in Porto Alegre, Brasil, and as if to follow the end of the season the work on Green Nomad is also changing somewhat.

The fitting of the internal furniture is nearing its completion. All basic structures are in place and now it is more a finishing job, fitting locker doors, ceiling and walls lining, floor non skid recovering and painting of the internal plywood in white.

For a duo that is fitting out an interior for the first time, we are in fact surprised by how far we have come.

The evolution of Green Nomad's home office!

April 2009

End of August 2009

When we were selecting the pictures for this email it came to our minds that we really ought to be missing a couple of screws on our heads, or that our comfort/discomfort threshold must be ways far from the normal.

We have been living aboard during all the fitting out, which only started really in March this year, when we bought and Marli started to fit the insulation Styrofoam sheets. From December 2008 to March 2009 we lived with the same provisional layout that we fitted in the boatyard. Two civil construction plywood sheets and some beams provided a floor during daytime and the beds at night, and all was improvised.

But little by little we started to gain ground during the last 3 months, and now, looking around we can see that our new home is nearly finished!

All we did was planned as not to interfere with the basic needs too much. Our galley had to be operational and we had to have a clean bed at all times. Sometimes that required quite a bit of flexibility.

Two of the most versatile square metres in Porto Alegre

Everything had more than one role, even the toilet seat!

Washing requiredsome skill

Cooking inside an almost bare hull!

During these 3 months we processed roughly the following amounts of building materials:

  • 10  10mm marine plywood sheets
  • 8 15mm marine plywood sheets
  • 50 2m lengths of Cedar wood in varied sections
  • 100 sheets of 1000x500x50mm Styrofoam
  • 4 sheets of 1000x500x20mm Styrofoam
  • 1 Formica sheet
  • 2 cans of contact cement
  • 3 tubes of glue for wood
  • 15 tubes of Sykaflex 221
  • 1000 screws

For the ones interested in values we spent in the above around 5000 Brazilian Reals, or some 2500 USD.

First time we went out and grabbed one of the 15mm plywood sheets to cut I thought that I would not be able to move it. But at the end of the day the two of us managed to handle them all, and today we can still not believe that inside our 11m x 3.85m hull we fitted 18 sheets of plywood measuring 2.5 x 1.6 m each!

Working in the dock at Clube dos Jangadeiros, in Porto Alegre

Our great luck, being welcome as guests by the Clube dos Jangadeiros, in Porto Alegre , Brazil. Without this safe port all things would be more difficult.

Preparing the Port diesel tank bed prior to the bedroom fit out

First things first: Our bed initiates the internal fit out!

We started by the aft cabin and went on clockwise, doing the galley, port settee, forward bunk, starboard settee, nav station, heads, engine box and finally the galley sinks that are on top of the lifting-keel box. The last touch was to fit the nav station backrest chair, which will hold us in the rough seas. Already on the first boat we had such an arrangement, with a longitudinal nav table and outboard facing chair, but then it was fixed. Now we can rotate it and even raise it 20cm in order to have a very comfortable watch position.

We are also well on our way installing the plumbing, and in two more weeks shall start the electrics.

One of our friend's kids explores the mad sailors cave. So much to see!

Today we can already receive gests for dinner with comfort and hope many of them will come here and in the places we plan to sail to in the near future.

At last a real galley!

A long way we have come since the meals sitting on the toilet

Madrugada's ex nav table was given to us by Niels Rump, from Farol Nautica, who is currently doing the restauration job to bring the old racing champion back to its golden days

The dual sinks that drain into the keel well

Navigating the web for now, but hopefully the oceans soon.

We surface mounted the heads washbasin to save locker space underneath and to be able to bring it as far inboard as possible, attaining full headroom above it.

For exterior fit out the only news for now are the fitting of the hard dodger frame in aluminiun tubing. We had a full cockpit enclosure on the first Green Nomad, what was easy to achieve due to the centre cockpit design, but now we are getting the same effect by fitting a drop down transparent back cover, which will be fastened to the cockpit seats and floor at the back of the hard dodger, something similar to what we saw in some of the Vendee Globe IMOCA 60 class boats.

Green Nomad waiting to get on her way to meet new and old friends!

We hope to have Green Nomad apt to sail away by the end of the year. Even though we are loving our time here in Porto Alegre, for next winter we long to be on some tropical location, trading oilskins for T shirts and boots for  Havaianas sandals ( a brazilian sandal that spread around the world ).

Luis Manuel Pinho, luisdesenhos@gmail.com is a member of our yacht design staff and presently is building his new Green Nomad. This time he chose the Kiribati 36, the latest B & G stock plan, mostly designed by him. As soon as the boat, which is being built in Porto Alegre, South Brazil, is concluded, he intends, together with his wife, Marli Werner, to return to the South Pacific, this time feeling more prepared to face awkward situations thanks to the swing keel system adopted in the design of the new boat.


Kiribati 36 Green Nomad construction latest news.

Luis Manuel Pinho, our new collaborator, is an engineer, yacht designer and cruising sailor of great personal experience. He travelled for nearly ten years to the most distant islands in the South Pacific aboard Green Nomad, a thirty-six foot home-built steel sailboat, in company of his wife, Marli Werner. He sold his boat in Australia and flied to Brazil, the country where he found the most favourable costs/benefit conditions for building a one-off yacht, and now he is building there a new Green Nomad, this time in aluminium.

The new boat, a Kiribati 36, our latest stock plan mostly designed by himself, is being finished in a very fast pace. The couple is already living aboard, an experience that anticipates future adventures they so anxiously are dreaming with.


You, who are following the saga of the enterprising couple regularly in our site, will like to know how they are doing:

“We are amazed with the productivity you can achieve doing the interior joinery work when you have it modeled in 3D in a cad program.

It has been less than 2 months since we started the interior building, and you can see in the pictures how far we have come!

Launch day....                                             Less than 2 months of work

Ideally we would have used the files to have all plywood parts CNC cut but, as most amateur boat builders, we have a tight budget, so our CNC is a not cutting edge but it works.

Using the projected plywood parts' shapes, we nest them manually in the area of a plywood sheet, and using our own CNC machine ( from Copy'n Cut) we hand copy them into A4 pages and walk out to draw them in the real plywood sheets, and using a hand jig-saw we cut the parts.

We pre-cut all parts like this. They come aboard with all the slots for fitting around the aluminum structure. Very little on the spot adjusting is needed. We got to mount 3 bulkheads in the same day!

Hand copying...

Transferring to the plywood sheet...



Bulkheads cut and ready to come aboard

We are doing all the work by ourselves and surprised with the ground we cover each day. Apart from the unstoppable sneezing due to dust, it is being an agreeable experience.

Each day the living a board gets a little more comfortable. Not long after a part is fixed in place it is summoned into service!

Settee being finished...

Settee in use!

One curious detail: A friend is doing the restauration work of one of Brazil's most famous ocean racers, Madrugada, and he offered us the old nav table, and guess what..., it fits perfectly in the spot allocated for it on Green Nomad!

Madrugada's nav table being fixed. It will sail again with Green Nomad!

An amazing feature is the dimensional precision achieved with CNC kit boat building.
The interior furniture modeled around the aluminum structure in the same cad program fits over it perfectly, with insignificant deviation from the computer model size.

From the structural joinery work we are only missing the nav station and the head. After that we will tackle the walls and ceiling linings, which will be done using recycled white plastic 2mm sheets.

And as not all is work, we are having some fun along the way, meeting old friends here in Porto Alegre. Today we received the visit from Anselmo and Tania, which came alongside in their steel MC37 37 Taihú, another boat of B & G Yacht design . We met them in the Caribbean in 1997.

A nice surprise with the visit from Anselmo and Tânia, from Taihú

Kiribati 36 Green Nomad

Hull number one of the Kiribati 36 design is floating since December 16th 2008, and the boat name is Green Nomad.

This boat is going to take their owners in a repeat of their voyage that started in Brazil and went across the Pacific Ocean, which only confirmed that the place they want to be in is some remote South Pacific Island.

The first Green Nomad was a van de Stadt 36 built in steel. Here she is at anchor in the Florida group of the Solomon Islands.

After selling the first Green Nomad in Australia in 2006, at the end of a 10 year and 20000 nautical miles trip, Luis Manuel and Marli  went back to Brazil, not because their love of the cruising life had ended, but family matters required their presence.

An unexpected turn of events saw them ready to take the cruising life again, but now they needed a boat!.  Even before they had sold their first boat, they already knew what they wanted from a new boat should they ever build another, and basically what they required is what you can see in the pages describing the Kiribati 36 design.

With the long dated relationship they had with Roberto Barros and the B&G Yacht Design team, the natural choice was to build one of their designs ( In fact, during their trip they met 3 boats from their design performing very well and praised endlessly by their crews ). Luis is a Metallurgist engineer graduated by the same university that formed Luis Gouveia and Astrid Barros, and many times they used to meet during their student years.

Having an old passion for yacht design, to the point of starting the Westlawn School of Yacht Design program some 20 years ago, Luis knew enough about the design process to know he had to find a partner to develop his first design.
So he decided to buy B&G YD new Multichine 36 SK design, and based on it produce the boat of his dreams.

Supported by the design office team and starting from an excellent and proven hull form, it was time to let loose the imagination and use his skills for computer 3D modeling and knowledge of fabrication processes to create the Kiribati 36.

In some aspects it is the exact opposite of the first Green Nomad, being light and built of aluminum, open aft cockpit and modern hull forms against a traditional center cockpit design. In others is just an extension, with the same attention to detail in the systems and the best equipment where it matters to ensure a trouble free voyaging experience.

Today the new Green Nomad's trip has already started ( new hull, same name and mission ). Luis and Marli are living on board since launch day, in Porto Alegre, Brazil, with an improvised interior.

Life on board for now is not exactly as seen in the pictures above, but slowly they are working to get there. Luis used the last months to finish the technical drawings for the Kiribati 36 design, incorporating lessons learned during the building of the first hull, and every now and then a new board is added to the incipient interior furniture.

The first load of marine plywood for the definitive interior has just arrived, and we expect to see the Green Nomad slowly turning into a voyaging home. Marli is finishing the thermal insulation of the hull and deck, and Luis has finished the drawings for the Kiribati 36 stock plans, and for a time now they will be shipwrights and riggers and all other trades in order to follow the call of the islands.

When things start changing you will be able to follow up on this site. We hope to send more conventional boat interior pictures soon!

Kiribati 36, our next stock plan

Soon we will be introducing a very exciting new design, the Kiribati 36, an aluminium sail boat with a series of innovative ideas, which we are expecting to excite the imagination of many blue-water cruising sailors.

This new design has all the ingredients to make a successful career. The story of the Kiribati 36 began when our friend, now our collaborator, Luis Manuel Pinho, a long time cruising sailor, accepted our invitation to produce this design in a joint venture.

Luis Manuel was born in Mozambique. When that country obtained its independence, his family immigrated to Rio de Janeiro, Brazil, where Luis Manuel obtained a degree in engineering. Soon after his graduation he built a steel boat with which, together with his just married wife Marli, sailed to the South Pacific, where they stayed for many years.

They established their base in Cairns, Queensland, and from there they visited many remote islands in the South Pacific. After four years of residence, Luis Manuel and his wife obtained the Australian citizenship, something important for us, since we also transferred our office to Perth, Western Australia.

Luis Manuel sold his boat in Australia and came back to Brazil to build his new yacht, since this was the country where he was acquainted with building facilities, based in his previous experience. Luis Manuel and his wife intend to sail back to Australia with the new boat, where they will resume to their former cruising life-stile, and he intends to remain as our collaborator in future projects.

The deal we made with him was beneficial for both sides. We used the Multichine 36SK as a base plan for the new design and he introduced the modifications he intended to accomplish, which we believe are shared by many other cruising sailors. The result of all his work is the Kiribati 36, which we are proud to advertise.

If you are interested in the Kiribati 36 and want to know more about this design, please send us an e-mail to info@yachtdesign.com.auor to Luis Manuel at the e-mail luisdesenhos@gmail.com.

Kiribati 36 Aluminium Swing Keel Yacht

Length Overall – 11.03m
Beam – 3.84m
Draft Keel Up – 0.72m
Draft Keel Down – 2.26m
Displacement Light – 7250 Kg (includes rig, winches, interior, deck hardware)
Displacement Loaded – 8750 kg (Full tanks, provisions, spares, dinghy, outboard etc)
Ballast – Fixed 1000 Kg
Swing Keel 1300 Kg
Water Capacity – 600 l
Fuel Capacity – 420 l

The main goals that the Kiribati 36 has to meet are:

  • - To be a safe world passage maker with emphasis on tropical sailing. A shallow draught is desired to amplify the cruising ground possibilities and enhance the safety of anchoring in otherwise inaccessible shelters.
  • - To be a permanent home for a couple with good view to the outside.
  • - To be cost effective to be built by amateurs or by professional yards.
  • - To have simple and reliable systems in order to minimize the possibilities of gear failure at sea and to keep the running and maintenance costs to a minimum.
  • - To be a reasonable performer in light airs and be capable of motoring comfortably at 5 to 6 knots, with a 1000 Nautical Miles range under power.
  • - To see how these goals are met with the minimum possible compromise by the Kiribati 36, we begin by its size.

11 m or 36ft LOA gives you enough carrying capability and can take its share of rough weather and the inertia for the proposed displacement still gives you gentle enough accelerations while this size still belongs to the small boat club in comparison to the current cruising fleet.

While 32 ft or 10 m can still be enough, the savings in cost will be not all that great, as a simply conceived 11m can be cheaper than an overbuilt, over-equipped 10 m long boat, and the trade off can be disadvantageous when you consider the smaller payload. You can benefit of cheaper places if you can carry more stocks and fuel.

Next we come to the building method, which is based on a pre-cut kit of all aluminium parts, numbered and identified in easy to read perspective drawings.

With this kit and drawings, and with the building manual supplied, an amateur with access to a shed and an aluminium welder (we recommend that an experienced welding professional be hired) can confidently put the boat together.

The hull plates are designed to be nearly 100% developable in a plane, so no great forces are required to bend them to shape and a minimum of stress and deformation is introduced in the material. This is assured by using dedicated software ( Prosurf 3, Rhinoceros ) that calculates and shows graphically the amount of curvature on the surface.

This hull is intrinsically very strong with the added advantage of the inherent dryness of properly built metal hulls. The 5086/5083 aluminium employed should ensure decades of trouble free cruising, as far as the hull is concerned.

The choice of twin rudders behind skegs with tiller steering is logical since you want to keep systems simple and still have low draught and good steering control. The twin rudders are 10cm deeper than the lowest part of the hull with the swing keel up, providing a stable 3 point base when sitting on the ground.

The option for a swing keel is dictated by the shallow draught requirement. With the keel up the Kiribati 36 draws scant 79 centimetres (2 ‘ 7” ) fully loaded. The ballast is divided between internal ballast and the ballasted swing keel. There is a very simple and low cost system to raise the keel, using an ordinary winch and a 4 to 1 reduction, pulling two 12mm spectra ropes.

The rig is a single spreader cutter in order to keep it simple and provide for enough sail area combinations for safe offshore passages. A mast height of 13 m and a sail area of 57 m³ to give a Sail area/Displacement ratio of 14.3 should power the Kiribati 36 well enough in the prevailing conditions of the trade wind belt. Slab reefing and mainsail handling by the mast is preferred to minimize line runs and keep chafe and costs low. A well protected working area around the mast is provided by back-rests on each side.

The outboard profile is dictated by the requirements of a good view to the outside and an easy transition from cockpit to cabin. A raised floor area just below from the main companionway hatch will provide a good view from the galley and navigation station area. Six 32x24cm  and  two 50x50cm hatches are installed around this cabin area, enabling integration to the exterior surroundings  and plenty of ventilation, while being safe and strong.

The Interior

The interior layout is very open and unobstructed with only the aft cabin and heads areas separated.

A raised floor central section accommodates the navigation station, where a seated navigator can look out through the hatches, and the cook has full view of the outside, providing for a comfortable and ventilated working environment.

Forward and one step below there is a dinette with ample sitting room for six persons and a forward double berth.

The heads is located to starboard, aft of the navigation station, and behind it is the technical area, concentrating all through-hulls, except the main raw water intake, which is located on the keel trunk wall, being this the only underwater connection on the boat. A convenient space for electric equipment, pumps and all diesel fuel management is also located here.


Kiribati 36 – A new design for construction with CNC cut aluminium plates.

It is well advanced the hull of the first Kiribati 36, a design adapted from our Multichine 36 SK and first of our line to be nearly 100% pre-cut by CNC. The hull is being built by Metallic Boats yard, in Triunfo, RS, Brazil

Main diferences from the Multichine 36 SK, which can also be built in aluminium in addition to steel, are changes to the deck and cabin, to allow a better panoramic view from inside the cabin, item that our clients, Luis Manuel and Marli, consider a priority for a long range voyaging yacht, and modifications to the systems in the direction of simplicity, low maintenance and low cost, as tiller steering instead of wheel, and new position of the rudders, now placed behind the transom. The anchor locker was brought aft and enlarged and an extra watertight bulkhead inserted at the aft end, creating a huge lazzarette isolated from the accommodation area.

The couple chose this design to replace their "Green Nomad", a Van de Stadt 36 built in steel by them, in which they cruised for 10 years, from Rio de Janeiro to the Pacific Ocean, passing through Panama and staying several years between Australia and the South West Pacific island groups. Between these, they were enchanted by Kiribati , reason why they chose to name their version of the design Kiribati 36.

Being a swing keel design, the Kiribati 36 will allow them to return and explore the Pacific Ocean with more freedom of choice and options than before, when they had to play the tides in order to get into cyclone holes and other anchorages.

The hull is in 5083 aluminium alloy, being 10mm thick in the bottom and 8mm on the sides. The hull panels were cut by plasma, while the remaining of the structure, deck, keel and rudders were cut by water jet. All was pre-cut, ensuring a fast and very precise assemblage. The modifications and the development of the pre-cut kit were done by Luis Manuel Pinho in close collaboration with our office, which shall launch an official version of the design soon.

Kiribati 36, our next stock plan

Soon we will be introducing a very exciting new design, the Kiribati 36, an aluminium sail boat with a series of innovative ideas, which we are expecting to excite the imagination of many blue-water cruising sailors.

This new design has all the ingredients to make a successful career. The story of the Kiribati 36 began when our friend, now our collaborator, Luis Manuel Pinho, a long time cruising sailor, accepted our invitation to produce this design in a joint venture.

Luis Manuel was born in Mozambique. When that country obtained its independence, his family immigrated to Rio de Janeiro, Brazil, where Luis Manuel obtained a degree in engineering. Soon after his graduation he built a steel boat with which, together with his just married wife Marli, sailed to the South Pacific, where they stayed for many years.

They established their base in Cairns, Queensland, and from there they visited many remote islands in the South Pacific. After four years of residence, Luis Manuel and his wife obtained the Australian citizenship, something important for us, since we also transferred our office to Perth, Western Australia.

Luis Manuel sold his boat in Australia and came back to Brazil to build his new yacht, since this was the country where he was acquainted with building facilities, based in his previous experience. Luis Manuel and his wife intend to sail back to Australia with the new boat, where they will resume to their former cruising life-stile, and he intends to remain as our collaborator in future projects.

The deal we made with him was beneficial for both sides. We used the Multichine 36SK as a base plan for the new design and he introduced the modifications he intended to accomplish, which we believe are shared by many other cruising sailors. The result of all his work is the Kiribati 36, which we are proud to advertise.

If you are interested in the Kiribati 36 and want to know more about this design, please send us an e-mail to info@yachtdesign.com.auor to Luis Manuel at the e-mail luisdesenhos@gmail.com.

Kiribati 36 Aluminium Swing Keel Yacht

Length Overall – 11.03m
Beam – 3.84m
Draft Keel Up – 0.72m
Draft Keel Down – 2.26m
Displacement Light – 7250 Kg (includes rig, winches, interior, deck hardware)
Displacement Loaded – 8750 kg (Full tanks, provisions, spares, dinghy, outboard etc)
Ballast – Fixed 1000 Kg
Swing Keel 1300 Kg
Water Capacity – 600 l
Fuel Capacity – 420 l

The main goals that the Kiribati 36 has to meet are:

  • - To be a safe world passage maker with emphasis on tropical sailing. A shallow draught is desired to amplify the cruising ground possibilities and enhance the safety of anchoring in otherwise inaccessible shelters.
  • - To be a permanent home for a couple with good view to the outside.
  • - To be cost effective to be built by amateurs or by professional yards.
  • - To have simple and reliable systems in order to minimize the possibilities of gear failure at sea and to keep the running and maintenance costs to a minimum.
  • - To be a reasonable performer in light airs and be capable of motoring comfortably at 5 to 6 knots, with a 1000 Nautical Miles range under power.
  • - To see how these goals are met with the minimum possible compromise by the Kiribati 36, we begin by its size.

11 m or 36ft LOA gives you enough carrying capability and can take its share of rough weather and the inertia for the proposed displacement still gives you gentle enough accelerations while this size still belongs to the small boat club in comparison to the current cruising fleet.

While 32 ft or 10 m can still be enough, the savings in cost will be not all that great, as a simply conceived 11m can be cheaper than an overbuilt, over-equipped 10 m long boat, and the trade off can be disadvantageous when you consider the smaller payload. You can benefit of cheaper places if you can carry more stocks and fuel.

Next we come to the building method, which is based on a pre-cut kit of all aluminium parts, numbered and identified in easy to read perspective drawings.

With this kit and drawings, and with the building manual supplied, an amateur with access to a shed and an aluminium welder (we recommend that an experienced welding professional be hired) can confidently put the boat together.

The hull plates are designed to be nearly 100% developable in a plane, so no great forces are required to bend them to shape and a minimum of stress and deformation is introduced in the material. This is assured by using dedicated software ( Prosurf 3, Rhinoceros ) that calculates and shows graphically the amount of curvature on the surface.

This hull is intrinsically very strong with the added advantage of the inherent dryness of properly built metal hulls. The 5086/5083 aluminium employed should ensure decades of trouble free cruising, as far as the hull is concerned.

The choice of twin rudders behind skegs with tiller steering is logical since you want to keep systems simple and still have low draught and good steering control. The twin rudders are 10cm deeper than the lowest part of the hull with the swing keel up, providing a stable 3 point base when sitting on the ground.

The option for a swing keel is dictated by the shallow draught requirement. With the keel up the Kiribati 36 draws scant 79 centimetres (2 ‘ 7” ) fully loaded. The ballast is divided between internal ballast and the ballasted swing keel. There is a very simple and low cost system to raise the keel, using an ordinary winch and a 4 to 1 reduction, pulling two 12mm spectra ropes.

Slab reefing and mainsail handling by the mast is preferred to minimize line runs and keep chafe and costs low. A well protected working area around the mast is provided by back-rests on each side.

The outboard profile is dictated by the requirements of a good view to the outside and an easy transition from cockpit to cabin.

The interior layout is very open and unobstructed with only the aft cabin and heads areas separated.

A raised floor central section accommodates the navigation station, where a seated navigator can look out through the hatches, and the cook has full view of the outside, providing for a comfortable and ventilated working environment.

The heads is located to starboard, aft of the navigation station, and behind it is the technical area, concentrating all through-hulls, except the main raw water intake, which is located on the keel trunk wall, being this the only underwater connection on the boat. A convenient space for electric equipment, pumps and all diesel fuel management is also located here.
