The design brief could not have been simpler. The boat had to be fast enough to win the 2009 World championships, but it must be also capable of achieving this “straight out of the box” Our goal is that the black art of “tweaking” will not apply to this boat in the way it has to other production designs, that those “in the know” do not have an advantage over your regular Jo.
Everything is just right, from the foils that are designed at exactly the right angle, to the sophisticated wand system, and whilst clearly the International Moth is a development class, care has been taken to ensure that the boat will work perfectly, straight from the box.
But the design brief was also to make a boat of such quality that owners would be proud, whether they are racing at world level, or just enjoying some free ride time on the water. Pride comes from not only having a desirable product, but a dependable one too, and as a result great care has been taken over the tooling, material selection and method of construction.
The hull shape has been designed to be as fast as possible at “take off” speed. This is the only traditional requirement of the hull, the rest of the time its in the air. And that’s where windage is important and the lack of any flair to the deck, the first on a production boat allows an easy flow of air around the boat from most angles.
The Dreadnought bow not only looks great but also reduces windage. Equally it minimizes resistance as the hull punches through waves going downwind in rough conditions. This means that the boat doesn’t “load up” so easily and is therefore more manageable and quicker.
The sexy transom, a feature that immediately catches the eye, is designed to put strength into that area whilst taking weight out.
Finally the unique triangular centerboard case is moved further forward to increase stability and share the lifting loads more equally between the two foils.
