Hi Kieran, Welcome to the forum......The design looks interesting. Keep in mind that Land Sailing is a worldwide sport but has a relatively small number of participants, The sport is governed by an international body called F.I.S.L.Y. and there is just a few yacht class designs, If you are going to design a yacht try and make it fit one of the classes otherwise it will be of very little interest to people around the world.
www.fisly.org/rules/ The most popular classes in the world are
Class5 / Class5 promo or
International Mini 5.6 yacht. So work your yacht design into one of those classes if you are wanting to do anything commercially.
Just something to keep in mind.... wire spoke wheels don't work well on land yacht due the side forces put on them.
