My new sail is a Pentax square top from Whirlwind and I trust Chip does a better job. I really do understand your frustration though. It sounds like what the 17 could do with a another place setting up a rival update fix program for the boat.

I have expressed on another thread the Wobble problem and asked for known fixes.
I think I will put an I-beam inside the beam as nacra do as holding the beam through one small skin section is just daft. I know I will end up with a bolt showing on the outside of the beam but for the gain in structural integrity I think it is a good swap. And having to re tighten the beam bolts regularly is just agricultural.
Good factory style upgrades would sell like hot cakes I am sure.
