Yes interesting point. He wasn't shy about telling the purpose of the transom designThat's a really nice-looking Moth!
I wonder just how low the faired portion of the gantry could be placed without being considered to be "an attempt at increasing waterline length" ? And how would the measurers determine the designed waterline?
Mike Lennon tried it - seems like he was unconvinced, but someone might come up with a better design in the futurePure morbid curiosity, do the moths sheet to the middle of the boat enough to make this a viable solution without a boom à la A class? Or is this going to be another funky-boom innovation?
Yes. Also that's not an 'either or' question. According to our modeling, there are numerous positive consequences to sealing the tack to the deck. 1. it eliminates the capacity of the foot to generate tip vorticies, thus reducing drag. 2. It increases apparent aspect ratio (think of it as making the deck a scoop for the sail), driving the CoP profoundly downward, thus shortening the heeling moment arm and generating far greater thrust capacity in the overall system.Question to Dave: in your opinion does closing the deck slot really make a difference, or is it mostly about heeling moment?
