heat gun (carefully applied heat!...not TOO hot!). You can use a razor blade if you are very careful with it. Usually with a little heat, once you get an edge started, you can peel for some distance if you keep it warm as you go.

A sunfish mast (or part of the mast) is the same dimension as the N20 pole plus a little length. You'll need to cut it down. Considering your remote location, you'll probably be much better off to find a sunfish mast than freight for a replacement pole. The spinnaker snuffing points ARE different, but they are easy to add and any sailmaker can add or rearrange them. I wouldn't use this as a make / break situation. we can help with the correct placement of the points when you get to that part.

Trampoline coming out of the track is a common problem. The solution is a big fat rope with nylon strops. The trampoline is then cut back, folded over, and has more nylon strops sewn into it. The tramp is then threaded to between the hull-mounted strops and the tramp mounted strops. This fixes it in most cases (the bigger rope). In some cases, folks have had to resort to plastic slugs or plastic rod in the hull to keep it from pulling out. Future boats went to a shoulder screw in the hull to lace the trampoline to and the milled groove went away.
