A FRIEND OF MINE HAS A BOOM BRAKE...
Jim, and he swears by it. He installed his at the point where the vang connects to the boom, then ran his sheets abeam to shackles connected to the toe rail. Makes sense to me and is in my future upgrade plans. So, you have the vang, that connects to the brake, that connects to the boom. It is safer than a preventer, especially when sailing solo.
