I've tried searching for articles in the forum about boom-vangs and , to my surprise, there were none.
So, I'm trying to devise a vang for my performance dinghy but it needs to be low-cost and powerful. A lever vang fits this description, but it may not have enough travel for this sort of rig (unstayed, very flexible). To address the travel issue, I've roughly designed a "cam" vang, in which a cam with a radius that is equal to an appropriate lever replaces the lever. Has anyone ever heard of such a device?
I don't want to spend a fortune on blocks, which is why I want to use a lever of some sort. Does anyone have any suggestions?
