I have what I guess is a stock '73 boat with a non adjustable block for running the jib sheets to a standard jib. I'd like to use a genoa, but have no idea where it should lead to, or how to mount an adjustable track for a snatch block, etc. Anyone done this? I saw an old 22 in poor shape at another marina where someone had screwed a track into the teak toe rail aft of the winch. Will that handle the load? Thanks!!
