I am a young naval architect from La Rochelle, France. I studied yacht
design at Southampton and aerospace structures at Cranfield University. I
was part of the design team of Mascalzone Latino in the 32nd America’s Cup
and Team Origin later on.
I have also worked on several projects for Juan Kouyoumdjain Yacht Design.

Later in July I will present a paper on the influence of structural
deflections (hull sag, keel structure) on upwind performance at the
InnovSail conference organized by the Royal Institution of Naval
Architects.

The SCOW 1420 pictured above is a monohull of 14.20m (rule maximum) having a flat bottomed
hull inspired by the A scows.

The aim is to maximize power for a given efficiency. Scow hull shapes
generate up to 30% more power than a standard hull shape for a given beam
and displacement. The long overhang forward reduces bow down trim and
increases waterline length when beating upwind or reaching.

There is thus
no need for aft water ballasts or to increase bow volume. The canting keel
can be used to heel the boat to leeward when the boat is under powered in
order to reduce wetted surface area.

This project was introduced during the 2008 Bol d’Or and both sailors and
organizers showed a strong interest. Since then, the boat has been fully
developed, a boat builder has been selected and the cost has been reduced.

The sailing conditions on lake Geneva tend to create highly powered sailing
yachts. The recent LX-TCFX ranking allows all extreme monohulls to race
against each other in real time. It is therefore a great place for naval
architects to experiment.

Recently, there has been a few lightweight multihulls and foilers on lake
Geneva. Foilers have still not proven to be the best solution for the
conditions of Lake Geneva due to the lack of wind.

The LX-TCFX ranking is generally won by one of the Psaros 40 (2nd in 2009,
1st in 2008).
VPP studies show that the Scow 1420 is 10 to 15% faster than the Psaros 40..

The next Bol d’Or will start on the 10th of June. – Thomas Tison.
