its not really very effective with hobie's due to their kickup system, the If you can get most of the rudder completely out of the water you get no weather helm. It works well on my nacra, but the rudder system is different. You are most defiately correct to not bother with it if weather helm is a problem, its not worth the tiny little edge it gives you. Plus if youir fighting weather helm its lsowing you down, its like dragging the rudder behind you in sideways in the water.
