Our yacht club has four 272's amd we all step the mast out of the water with an A-frame arrangement using a metal or PVC gen pole and either rope or cable leading to a bridle centered at the chain plates. We all use a line or stap from the end of the gen pole to some kind of mechanical advatage hooked to the bow. I use a winch hooked to the trailer, others use a block and tackle(3 or 4 to 1 boom vang). Another guy uses a block with the line running to his headsail winch. I don't have any pictures but you can find similar arrandements on the net. It is not that difficult if you have someone looking for hang-ups and take your time.
