Yes, two
line is the way to go. Simple, reliable, less
line to haul, less friction, great sail shape control, cheap, allows different boom angles for heavy air vs normal, in other words everything you want out of reefing system. While single
line seems like a great idea, there is a lot more
line to haul, a lot more friction and heavier loads to deal with. One important tip is to mark the main halyard at its proper position. If you do you can simply release the halyard to its mark and pull in the tack
line by hand without even needing a
winch. Then all youy need to do is pull in the clew
line which does very much require a
winch near the end of its tensioning.
