Swan 40 upwind
Close-hauled I find that on starboard tack I can sail 5+ degrees closer to the wind than on port tack. I have had the standing rigging alignment and tension checked by an expert but apparently everything is in order.
Any ideas ?

HI Richard,

My first guess is alignment.. How did the expert check it? Did he use the main halyard? If so do you have a setup for two main halyards and did he account for the offset if you do?

Again I defer to Lars...

Fun Fun

Dear Mike and Richard
I think Mike is on the right track, the wind unit at the mast head may be 2 deg off the proper alignment.
Kind regards
Lars

Dear Richard,

How are you measuring the difference? If you're using technology, that may be the problem. I doubt this is the case but you may want to compare the windex at the mast top with the instruments. I chartered a boat recently that was off by 10 degrees. It took me several tacks to realize my mistake.

Good luck,

Thanks, I will start by checking the masthead unit alignment
