My Hunter 18.5 came with one small winch mounted on the mast. I have since led the halyards aft through a deck organizer to horn cleats at the aft edge of the cabin top.
The winch on the mast being useless now, I removed it. I had thoughts of mounting the winch on the cabin top, forward of the main halyard cleat, but the handle won't clear the starboard stanchion (which supports the nearly useless shin-height lifelines). In the meantime, I can raise the mainsail most of the way without any leverage, then sweat it up (horizontally) for some tension, but not quite enough. Track lube on the sail slugs should help, but in order to get proper tension, I think I need some
The thought occurred to me that I could put a block and tackle arrangement at the masthead. Instead of shackling the main halyard straight to the headboard, I would shackle it to the masthead, placing a block in line between the masthead block and the now dead-end of the halyard, and shackle the headboard to that. The concept is illustrated in David Seidman's The Complete Sailor
, although it is shown for a jib halyard rather than a main.
So before I go running off on this concept, somebody give me a reality check here. Aside from making the main halyard twice as long, what am I not thinking about that would make this a bad idea? I'm only getting 2:1 advantage at best, not counting friction in the headboard, mast head, mast base, and deck organizer blocks, versus the much greater leverage the winch would give. But I've got to be missing something else.
