The Bladerider, Mach 2 Moth and KA Sails designer Andrew McDougall talks foiling and Moths
Moth guru Andrew McDougall is Europe at present, having first attended the Italian Moth Nationals and Foiling Week on Lake Garda and this week has been sailing the Moth Worlds at Hayling Island Sailing Club. At Foiling Week McDougall was addressing the wider issue of foiling generally…Since what were felt at the time to be the seemingly impossible photos of Rohan Veal foiling (now more than a decade ago), the Moth has become the first popular and commercially successful foiler, following on from Hobie’s attempts with their Trifoiler, the production version of Russell Long’s. But oddly, for the most part this has failed to be scaled up in the monohull world. McDougall gives his thoughts on the reasons for this: “Really it is like why you buy a bicycle and not a tricycle: It just works at that size on a small boat, because you can carve it, and you don’t get thrown off when you go around a corner like you would on a tricycle. It is quite natural to sail, whereas I have sailed Brett Burville’s boat, where I got completely ejected when I tried to turn it. As you turn it goes this way and accelerates and suddenly you are just gone!” Brett Burville’s Moth had more of a trimaran-style set-up with lifting foils mounted beneath the wingbars. McDougall continues: “It is exactly the same mechanics with a bike. Scale it up and it is why most people drive cars - it is more practical, easier, etc. The Moth is the perfect size for the bi-foiler. I don’t think realistically it works as you have more people on it.” This is why more larger foilers have been catamarans, he maintains. He also likes the simplicity of the Moth and its ‘bi-foiler’ format, how you can sail heeled to windward to
