The WindPaddle Scout is an amazing little sail. I had been using a 42" golf umbrella for a couple years with my WS Tarpon. This year I took a Mohawk 16' canoe to Cranberry lake in the ADK preserve for four days. I had mounted the sail on the center thwart and popped it up as we turned downwind. We were cutting wake for 3 miles, then turned across a bay and although the wind was a breeze there, we sailed crosswind 2 miles in short order and pulled right up at tent site, only use of paddle was as a rudder.
Great product, fun and practical. Wife got to read her book all the way back on 3 days of excursions. No boat should be without one.
