Great information guys. This particular question was raised by a couple of us at the bar last night. My boat has spreaders, but they are stationary thus you can not pre-bend the mast. Another guy had a H16. Another guy is an H20 driver.

We were talking about the cut of the newer Hobie 16 sails in relation to what Hobie did in the mid/late 90s to Hobie 20 sails. The old H20 sails oringinally were cut very generously thus a bunch of pre-bend was the main way to get those sails under control. Then the cut changed around 1996-1997. A lot of guys kept the same amount of pre-bend but rotated more.

I told them to change the spread angle and tension and screw rotating the mast on the H20.
