Beneteau 361 wheather helm
The boat''s excessive weather helm was either your fault, or the boat''s fault.
If the problem was caused by improper tuning of the rig, then the whole rig needs to be adjusted more forward, not aft. The objective is to move the center of effort of the sailplan forward, so that it is closer to the center of lateral resistance.
The problem also could have been caused by carrying too much mainsail area for the windstrength, or by carrying too much combined sail area for the windstrength. If you had a whole 130% headsail unfurled in 20-25 kt. winds, that was certainly too much headsail. Double-reefing the mainsail would have helped, but if the power generated by the jib alone is excessive, you can drop the mainsail completely, and the boat will still heel excessively and have excessive weather helm.
You said you let the mainsail out until it was completely luffing, and the boat still had excessive weather helm. That means the boat was overpowered when it was sailing on the jib alone. If you had reefed, or perhaps double-reefed, the main and rolled up about a third of the jib, I suspect the boat would have been much better balanced.
I''d like to assure you that it was the boat''s fault, Magnus, but if I had to guess, I''d bet you unfurled too much sail area for the windstrength. 20-25 kts. is a lot of wind for a 130% jib and even a reefed mainsail.
