Approach

Low drag !

​

Reducing drag leads to design more efficient hull shapes with regard to propulsive energy.

This automatically lower the required power, whatever sailing or motoryacht is concerned.

​

I take great care of that when designing racing yachts but also cruising ones and workboats.

​

The saving is measurable in speed, fuel consumption, and material thickness.

Here is Bagou, a coastal cruising catamaran powered by electric engines

Cat-boats

​

A cat-boat is more efficient than a sloop due to the reduced drag, the higher aspect ratio and the greater angle of incidence. Proof is not to be made anymore as you watch olympic dinghies.

​

It is still relevant on bigger boats such as the Ikone range and the 42 footer H2A where simplicity and efficiency combine very well : this just requires to change the way to control the sails !

​

I also use the cat-boat rig for cat-ketches, on ocean cruising yachts, such as the Medium and Wakame ranges.

​

Here is the Ikone 7.50, Boat of the year 2016 by the french Voile Magazine.

Wood

​

The wood material used in yachtbuilding is usually light, strong and aesthetically pleasant.

​

Strong and heavy boats last for a long time mainly because any piece of wood can be repaired or replaced by a new one.

Very light structures may be built when associating wood to light core materials such as foams, balsa  or cork. Repair is not that easy in this case.

​

There is probably a gap where designers and structure engineers could find a quite light wooden material that shipyards could repair or replace for years without exessive use of epoxy resin.

I am looking for this gap.

Green composites

​

Flax fibers, flax/balsa or flax/cork sandwich panels with green resins  give rise to high specific mechanical properties with a low environmental impact.

​

I use them as well on cruising baot (Marlin 32') as offshore racing yachts such as the Mini n°791 - in the top 5 prototype ranking 10 years after launching - or Class40' Flax40'.
