Boom Vang Rule of Thumb

[kristian]

KInda like the twin vang idea, I think then they're techinically twin preventers. Udells and 22sqm use that setup.

Upwind and close reaching, the leech tension is all done with the mainsheet on a Shields. When racing we actually find it lots faster to leave the vang slack until downwind.

You could always put a curved traveler track on the cabintop to run the vang too, like a Star.

Honestly I think the least intrusive situation would be to install a standard 8:1 vang with the bail as low as possible. It would probably work well enough for anything but a long reach, in which case you could rig a removable preventer tackle.
