I seem to have a serious problem with the stability of my boat. I recently fitted a Hydrovane Self Steering gear through the bumper offset to the port side. My boat now has a list of about 5 degrees to port. When a heavy crew member stands on the starboard side in the opposing position it makes no difference. A friend and crew recently took the boat to Gran Canaria in preparation for the ARC. It was sailed with a lot of weight in the lazerette and the boat screwed to windward in force7 so much that it broached several times. They are experienced sailors and assure me the sails were well balanced. They did not use the wind vane. On arrival in port they moved all the weight from the lazarette and distributed it on the port side but the boat still has a 3 degree list to port.
