Interesting video. I think the biggest problem with the boat is the shape of the bow. On a boat going that fast you’re going to be faster than the swell, which means you’ll consistently be driving into the back side of the next wave, and the boat is long enough to span a decent portion of the wavelength at the trough. That’s also compounded by the fact that your spinnaker and main are all pulling forward and putting downward pressure on the bow. Most other boats designed for the Transpac have a bunch of hollow in the bow to create lift to get the bow riding up and over the next swell, and maybe a little more stern rocker to create suction at the stern to help counteract the downward pressure on the bow from the sails. All surfboard design concepts as well, not by coincidence I don’t think for boats intended to surf all the way to Hawaii. Your boat is beautiful, but looks best designed for beam reaching and going to weather as opposed to riding up and over swell on a down wind, down swell run. That same bow is for example used on cargo ships to create more kindly sea motion onboard while pushing head-on into swell for the exact reason that it digs into the sell a bit before rising up, creating less hobby horsing. In my opinion, it’s a poor design choice for a downhill sled.
Nice work. Yep those boats leak like a sieves. See lots of owners trying to shed weight by taking less crew and less sails. Then taking on 20KG of water every 30 mins. Great stuff
