On our crossings we normally have a downwind course. When the wave's
come in at say between 120 and 160 degrees our boat tends to roll a 10
degrees over starboard and 10 degrees over port. What I do is getting
the weight as low as possible, even out as much as possible the sail
surface's at port and starbord, and sometimes steer another course. I
wonder if you are familiar with any further techniques I havent
thought of yet.

Changing course is the easy, low cost solution. If you want
something better than that, you might want to consider flying
paravanes from twin whisker poles. It takes quite a bit of rigging
and practice to get them set them up properly and deployed safely.
They are quite effective however as demonstrated by the thousands of
commercial fishing trawlers that use them.
