Why not suspend the flexible solar panels, like trampolines between the rear of the floats and hull, behind the aft arms? Leave the Tramps clear. Your power vs speed curves are very impressive. My 4.5m sailing dinghy, uses around 200-250 watts to go 3 knots.

Good Idea I will look at putting solar there to see how I might do it. I agree on the power vs speed. I have been pleasantly surprised also. I think the long and narrow hull helps. This boat is also really light for it's size.

I just uploaded another video of a 20NM trip on a calm day. 20NM average speed 4.7 knots, I used just over 3kw.
