Talking foiling and all things fast, Andrew MacDougall is a leading innovator in sail and hull design and has been for many years. Owner of KA sail, he is something akin to the godfather of the Moth class. Let’s not forget he is also the inventor of the Waszp. Stephen Brayshaw talks it through with Andrew from the beginnings, how his designs have dominated the Moth class for 12 years, those complex systems onboard the Moth, the evolution of foils, fairings and how important these are and in general and just how much faster are the boats going to go? Will we see this speed difference again in 10 years time?
