We recently purchased a Hunter 280 and will have to transport it to Colorado and a new trailer as very few 280s have trailers. The question is that I purchased a Mast Crutch from Hunter and as they have sold very few of these, they did not have any instructions as to setting it up. The base of the Mast Crutch is an open pipe and I am concerned about the damage to the boat's surface. Has anyone used a Hunter Mast Crutch?
