See what your helm thinks. This is a special situation where the crew moves to aid steering so the helm uses less rudder and therefore less drag. In decent sized waves you need this technique most. When the boat heels, a lot of rudder has to be used to get the top of the mast back over the boat . But the crew, sitting to windward can use their weight to get the boat upright more efficiently.
Timing is critical.
Get used to which part of a wave will make the boat heel to leeward. Trapeze high from the case or push block and as the boat heels straighten the body. In marginal conditions, with good timing a legal roll will help you to the front. Now you know it, get out there and practice, practice, practice.
