with a bridle rigged to the mid-section of the boat or aft, which pulls the boat to a 15-30-degree angle to the wind? You can use a long dock line, tie it to your rode with a rolling hitch, and attach it to a cockpit winch to experiment and make adjustments. It should sail a bit to the one side and settle in right there, steady.

Same concept as a multihull's bridle, but asymmetric.
