The Flashheart Design

After considering all round preformance Moths spend more and more time in the air so a hull should be deigned to fly. This means as small as possible and and the dynamics of lift off should be considered.

A hard chine design sheds water better on contact with it. It should shed it to keep wetted area down and bounce back into the air. On take off is should also get rid of the water to allow the hull to lift off. Round hulls are better submerged but there is a lot of water around them when they make contact. In ten years Moths will rarly race in submerged state so lets forget about it and consentrate on the future.

Comertial builders need to be conservative with hull designs mainly becuase of tooling costs but we can be a bit more radical. The big advantage of this attitude and design is the easy flat panel build.

The DXF file can at: http://www.culnane.net/dc/moth/prj/Flashheart/FlashheartLines.dxf can be printed full size on two A3 sheet of paper. The frames marked and cut out on cheap chip borad. Then positioned and aligned. Remember that you have to take off the skin thickness (~7mm) from this drawing when marking frames.
