Can you give us a better idea of how the
boat is rigged? Is there a track on the
mast or does it use
mast hoops and jaws on the gaff? Is there a
bowsprit? Is there a topmast?
Spinnakers are often flown on some of the
classic racing yachts and occasionally on more cruiser oriented gaff rigged
boats. Given your rig proportions, it can often be difficult to keep a spinnaker clear of the headstay on gaff rigged
boats due to the low angle that it is at. In addition, the pole can be hard to attach at the mast end if you have hoops and jaws. From a setting standpoint, a gaff sail will blanket the upper part of the spinnaker more so it can be hard to keep it filled in certain conditions. It really will depend on the proportions of your rig. Flying a spinnaker solo is never easy, make sure you try it a few times first with someone else on board. Also, do you have an
autopilot?
