I've owned my h16 for one summer now and am starting to get the hang of things. I can't seem to ever pick up speed sailing downwind though. I notice that my boom sticks way up in the air when it's sheeted way out and the sail won't hold it's shape. My question is, do people with small hobies ever use boom vangs? I see them sold everywhere, but have never actually seen one used. Most booms i see don't have a tang for one either, but i think mine does. There is a tang that looks like the mast tang for the shrouds that is about three back from the mast on the boom. Is there another use for this tang? Any help would be great!!!
