Made a real nice 5' luff, 7' foot anchor riding sail. Tried it out at anchor in about 10-15 mph winds. Sheeted it off to one side of boat. Seemed to hold boat steady, but then all of a sudden the boat would sail through the wind, back-winding the riding sail and slap it back and forth (noisy) until the boat swung back to its original position. My boat is a Cal31, light displacement.
Is this what a riding sail typically does? If not, what can I do to keep it from back-winding? I wonder if it would help to cleat the anchor rode to the opposite side of the boat the riding sail is connected to creating more of a turning moment to one side (I usually run the anchor rode through the bow roller, which centers it on the boat).
