Here are many proa layouts. Many of these are old designs and I am not happy with them. At the moment the top one would be my favourite. I have even more layouts. Many of these may not well work. The main intent is simply to get many designs out there to stimulate the mind. Thus many layouts are shown rather than a few refined designs

Below find some early drawings for a 56ft pacific proa. If I had more money that I could ever wish for, this is the boat I would build. Note the spars to windward and the way the rudders are protected by the large rocker of the hull. Looking at the diagrams now, many months after they were made, it is now obvious that the rudderboards need to be closer to the ends. This would ensure protection to the rudders on grounding by the rocker in the hull.
