371 won’t point

I love the head spinning part.

Trying to find factory rake settings is like trying to find hen's teeth.

My 400 obviously has too much rake, with a standard forestay length, possibly as a result of the mast foot being trimmed before I purchased it. It won't point, and rounds up with a gust of 12-14kn despite rapid mainstream release.

Good luck.

Do you know how much weather helm you have sailing close hauled in 10-12kn in smooth water? If you have a rudder angle indicator (normally if you have autopilot you will have this information available on chartplotter etc).

You need to have around 3 degrees (or maybe 4) of weather helm in this situation, and that provides "lift" which means you sail higher. Weather helm should not exceed 5 degrees in this situation.   If you can see and hear turbulence from the rudder then you have more than 5 or 6 degrees of rudder.

If you don't have enough weather helm, but all your sails are trimmed about right, then possible solution is to rake the mast bake slightly by adjusting forestay to be slightly longer.
