My partner and I plan to store the boat with the mast up. We would like to get a Cruising Spinnaker for next summer.We don't have a spinnaker halyard. The sail would only be used for long off the wind legs while on a cruise. My question is it possible to hoist the sail on a a spare jib halyard and fly it as long as we don't jibe it? I would suspect that if we had to change course we could drop it and reset it on the other tack. Your thoughts please. It's a masthead rig.
