Great video. Getting back into windsurfing after many years. I took out my equipment from the garage, dusted it off and realize how old it was. Sails, boom, mast, all from the 1990’s. These new rigs look a lot better.

Jim Oates says:

Nice one Jon – I had no idea to be honest as I had never rigged a pre-battened sail before. It was very saggy as I was not pulling the down haul tight enough. Cheers and thanks again
