I want to add a boom vang to my 272. The block for the reefing line that attaches to the base of the mast interferes with the position of the vang. I believe that the 272LE has both the vang and the reefing line. I would appreciate it if a 272 or 272LE owner could explain how to move the reefing line block to accommodate the vang, and also, what vang is recommended. Thanks.
