First off, 3 degrees of weeather helm is not bad at all... most of us rake the rig more to induce weather helm for lightish winds.
Heeling at 30 degrees will produce weather helm. 10-15 degrees of heel is better. ... some suggestions:
- draft location in the jib should be 40-45% or so. If it's aft of 50, that will contribute to heeling. More jib halyard tension.
- Same with main... draft location should be about 45%. Add more main halyard tension if possible.
- Flatten the main ... backstay on tighter (of course this will move draft aft in the main, so you'll need more main halyard).
- Drop the traveler down.
- Get the jib trimmer up on the windward rail.
