The solar cat pictured looks like it would work on flat water. I question if these people have been to sea before. The solar array made like a roof I believe to be very dangerous. The route they are going to take is fairly benign. I believe one or two things or both could happen. First the top could be blown off. That is a large sail area and anytime the wind is not parallel to the to the top great pressures could arise. Also under the same conditions the boat could be lifted up and unpleasant things could happen. My choice would have been to make more of a regular cruising cat and put the panels wherever they could be fit. I wish them luck. Dennis Raedeke
