Hi Brian, thanks. Hey that's a good idea for a revision. I'm making the prototype pretty slowly/working through the bugs as I go. I can see how, once you have a functioning prototype, it might be easy to build something like this out of composites. I'm kind of curious how it deploys... maybe it's spring loaded with bungies. Now that is something I might like to try in the beta version: pull a line to deploy the rudder... let it out (slowly) and it flops back up on deck (or vice versa). On most of these projects I try to integrate almost every suggestion (or part of it) into the final design.
