I'll watch this thread with interest... It seems as if the Tiger mains are about the only good used sails in surplus these days...
The length of the whole sail is probably a few feet too long... but I suspect the foot will be to long as well meaning a re-shape of the sail... I'm sure as long as you start out with enough material you can whittle it down to the correct size...
I am interested in this also for my SX 18, which is supposed to be a very close match
Remember the Tiger has some pretty good mast pre-bend. Pre-bend is do-able with an 18 with diamond wires and spreaders, but a 17 with no way to pre-bend the mast will make the sail shape, more than likely, never work quite right.
Yes, the H-17 sail delam-delema! I'm in the same boat!
