Greg,What I did was to get some 1/2 inch pvc pipe at the hardware store, and cut a slot in it to accomodate the sail slugs. Then I tapered the top end to ensure the slugs would slide in easily. The pipe is then inserted into the mast slot, although the mast has to be either off, or lowered sufficiently to provide access to the bottom opening. The lower most sail slug is fixed to the lower end of the pipe with by drilling a very small hole through the pipe and sail slug, then a small nail is used as a pin and trimmed off. The length of the pipe needs to be equal to the length between the boom and the top of the mast slot opening when the boom is at the lowest position.This system has worked well, never jammed and doesn't require drilling any holes in the mast.
