If your sailing well then you should not need to raise your trapeze height in a blow as the windward hull should still be just going through the peaks of the waves.
Makes me work harder on the mainsheet trapezing low as I dont want to be teabagged, its more stable too.
Set my dogbone up on the Mozzie with the upper ring level with the deck at the chainplate. The boat goes into the next gear whenever I can get into the lower ring so I accept the occasional teabag. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
