MULTICHINE 28

The MC28 construction system is the result of a long experience acquired in the application of the most reliable building technique for amateur construction, the so-called plywood/epoxy building method. Plywood is an easy to find, dimensionally stable and extremely strong material for its weight, and when its surface is saturated with epoxy resin, it lasts for many decades without showing the least signal of aging.

Saturating internally and sheathing the outside of the boat with fiberglass saturated with epoxy, the durability of the boat is indefinite, since the first boats designed by our office built according to these specifications, after more than thirty years of usage are still in excellent state of conservation.

Our approach to the construction of the MC28 is of emphasizing the pre-fabrication of the transverse structure that provides the boat’s framing and shape. These structural components consist of bulkheads, or semi-bulkheads, strategically located at full stations.

They should be built to the most advanced stage of construction possible before taking them to assemblage. This is important, in our opinion, because if these pieces, which are quite easy to be produced, are correctly built, the remaining of the work represents very little difficulty.

That is the main reason, we reckon, that so many amateurs have successfully concluded the constructions of their MC 28, even if they didn’t have the slightest previous experience in boat building.

The construction of  the MC28 follows a logical sequence, not intending to provide shortcuts that in our way of thinking are only illusory, like, for instance, the stitch and glue building method for larger yachts, which we do not consider advantageous.

We substitute the expensive epoxy filleting along the internal edges of the chines for wooden clamps, easy to be installed and costing peanuts if compared to the large amount of the so expensive epoxy necessary to accomplish the same function. What we call an illusory feeling is the sensation of having a hull assembled in a fortnight, remaining everything else to be done later, in a much more awkward position and with considerably more difficulty to proceed with the work.

The time to sheath the structure with plywood according to our method is the same or perhaps smaller than to assemble if stitching and gluing, with the advantage that you work on a solid foundation.

An important factor in assisting the amateur during the whole process of the construction is the building manual supplied with the plans. This book covers, step by step, the whole construction, giving precise information about each chapter of the construction. The index of the manual includes the following chapters:

1. – Introduction
2. – List of plans
3. – Basic dimensions
4. – History of the Multichine 28 Class
5. – Safety precautions
6. – Tools required for the construction
7. – About  wood and epoxy
8. – Constructing the hull
9. – The fibreglass encapsulation
10. – Building the interior
