Multichine 28

The MC 28 is the most popular design in our list of blue water sailboat stock plans. When we decided to develop this model we had in mind offering a high quality cruising boat to the amateur builder. Our intention then was to produce a stock plan that allowed persons with no previous experience to build the MC28 without difficulties. Simplicity of construction was our first priority, however, no matter how important this approach could have been, the final product had to be much more than simply an easy to build cruising boat. It had to be above all an exceptional blue water cruising sailboat.

Interior layout

Taking into account the optimized usage of interior space, which in this design is fully achieved with its every single space being utilized from anchor well bulkhead to transom, the MC28 rivals in comfort with much larger boats. Consulting our many clients who own, or are building a MC28, we made an interesting finding: the main decision factor for most of them in choosing the model were due to interior arrangement layout. Basically our clients in general dream with the possibility of living aboard for long periods or to accomplish extended cruises, and for these purposes our design is hard to be matched in appeal and functionality by other yachts of the same size. A thorough description of the interior layout will help in explaining this statement:

The saloon is large enough to promote a small party. Rendered image: www.ideebr.com

The aft cabin with its private hall, exclusive settee, a profusion of lockers and a large double berth, offers the comfort of a stateroom. The unusually large deck bridge under which one can sit comfortably without touching the headliner, gives an unequalled sensation of spaciousness, different from most other yachts of similar size, where this compartments are rather claustrophobic. An opening port in the transom, and another at the cabin trunk sidewall, provide good illumination and air circulation even if the cabin door is shut. The cockpit side and front walls are also adequate for the installation of other opening ports too, if wished. The fact that one can walk with 1.85m headroom from the aft cabin to the main saloon, contouring one of the most ample galleys to be found in twenty-eight footers is something that really enchants potential owners, and perhaps is one of the most decisive factors of convincement.

 To starboard, opposite to the galley, is installed a very spacious heads with room for vanity unit, sink, shower sump and toilet. Abaft the heads there is a large compartment for stowage of bulkier equipments, such as inflatable dinghy, awning, sails, etc. A gas locker draining through the transom is the only compartment with direct access to the cockpit. The integrated fuel tank is placed just abaft the toilet, and is only a few centimetres higher than the toilet sole. Over the tank cover there is place for a sewage holding tank, still leaving a corridor for stowing long items, like paddles, outboard motor for the dinghy and so on.

The navigation table either can be used from the dinette aft seat, or standing on the corridor. Rendered image: www.ideebr.com

The L shaped galley, besides being jumbo sized, it also allows the cook to stay out of the traffic from the companionway hatch. Two sinks, icebox, stove and ample space in lockers, ensure a comfortable usage for living aboard or during extended cruises.

To starboard, facing the sinks and icebox counter, there is an ample navigation quarter where the navigator seats facing aft, using the aft seat of the dinette. This dinette is V shaped and surrounds a two leaves hinged table. Forward, another double berth extends up to the collision bulkhead. When required, a curtain separates this fore berth from the dinette, allowing the usage of the table area without disturbing those who would be using the berth. This fore compartment is served by a hatch, a necessary convenience, particularly in nice weather, when the hatch may be kept open for maximum ventilation.

Another outstanding feature of the MC28 is its tanks capacity, carrying 420 litres of fresh water in three integrated tanks and 120 litres of fuel, affording a very large range under power. The tanks being integrated to the hull are leak-proof and are practically immune to condensation, a desirable feature for protection against water contamination of the fuel due to water vapour condensation.

The galley counter, besides its two sinks and 120 litres fridge compartment, still possesses a deep well under its fore surface, a very convenient feature seldom found in other boats. Rendered image: www.ideebr.com

Deck, cockpit and coach-roof

Outside, the Multichine 28 is designed to be functional and easy to be constructed. With a small cabin trunk and a flush, unobstructed fore deck, there is even room for a solid dinghy to be stowed there. The Dinghy Caravela 1.7 was designed custom made for the MC28 flush foredeck. Downloading the plans is free, and you find it in our list of stock plans. Some of our clients built the dinghy before they built the boat willing to get acquainted with the plywood/epoxy building technique, common to both crafts. Since the cost of building this dinghy is insignificant and the fact that it will be a good option for the boat tender, we advise building it as a preliminary training.

An unsinkable custom designed dinghy to be carried on the MC28 fore flush deck is one of the many special features of this project. The Caravela 1.7 can be rowed, used as a sailboat, or propelled by a small outboard motor. Rendered image: www.ideebr.com

 The cockpit is large enough to be used in warm nights as an extra double berth, provided that the cockpit grating is lifted to the level of the seats, and cushions or sleeping bags available for this purpose are extended over the area. The traveller, placed on top of the coach-roof, keeps the cockpit uncluttered, significantly enhancing its comfort. The dodger, when installed (we strongly advise to do so), does not interfere with the mainsail sheet, and the sheet control is easily accessed even by the helmsman, since the sheet tail is at a short distance from the tiller. The boarding platform aft, with its swimming ladder, is quite handy, still serving as a bumper in case of collision from abaft. Another practical solution, a trade mark of the design, is its vertical transom, with its externally hinged rudder. The simplicity and low cost of this arrangement fits nicely with the purpose of ultimate simplicity of the design.

The functionality of the boarding platform is unquestionable. The transom hanged rudder is easy to be maintained in spite of being practically trouble free.  Rendered images: www.ideebr.com

When defining the characteristics of the project we decided that above all other things the MC28 had to be an open sea cruising sailboat. So, we did not provide any direct access from the cockpit to the interior except if the owner wishes to install an opening port on the portside cockpit sidewall. The compartment under the starboard cockpit seat is the gas locker, which is separated from the interior by a tight wall.

The MC28 cockpit is adapted for extended cruising. Tiller steering and closed cockpit aft wall enhance the feeling of safety. Rendered image: www.ideebr.com 

Mast, rigging and sail area

The MC28 is a mast top sloop with one pair of spreaders and two pairs of lower shrouds. This is by far the simplest and most reliable rig configuration. The design also contemplates an optional sail plan with larger sail area and a taller mast with two pairs of spreaders. This plan is intended for those who wish to participate in club races and have little interest in extended cruising. Both plans are top rigged and posses two pairs of lowers.
