Step 6: sailing away
Worked like a charm. It was very strong (shown by the two times it flipped out of the back of my truck on to the road on the way to the lake) and light. The times it hit the road made some holes in the tarp which I fixed with some duct tape just prior to launching. I think I will add a peice of plywood and a coushin to raise my butt up a little to make it easier to row.
