Cattail:

We had waves about like yours at the Texas City Dike. Trick I always used was put the boat at water edge and pull the wheels out. With the rudders locked up I would push the boat out from the front crossbars and jump on one of the bows. With the sails loose the boat will back itself out AS long as you stay on the bow and keep the sterns out of the water. WHEN you are far enough out, just go back and put the rudders down and fall of the wind and head out. Works great.
