I only did it once on a Lancer 25. Tons of info on the main boards and online. My preference was a gin pole because I preferred to have the mast raised/lowered aft rather than with most of it hanging over my truck or overboard (I did it once on the water). I made a vee gin pole out of electrical conduit smashing the ends flat nod drilling them to connect at one and. The other connection was at the chain plate so the flattened ends were perpendicular to each other. I then drilled holes near the vee for two eye bolts. One up and one down for the lines. I ran a line from a sheet winch to a block at the bow chain plate to the bottom eye and connected a halyard to the other eye (as I recall). It was a two man operation and very scary when the mast is near straight up as it can go port or starboard and then you have real trouble.I'm working on the same thing as well... I'll be figuring out a system that will work with just one person. Trying to decide whether to use a separate gin pole system, or use the boom as a gin pole.
