Although not answering your question, I installed a CPT
wheel pilot for this purpose, as well. I'm mostly
single hand and I need to be able to use the
head, grab some
water or grab some
food. For longer periods of time, I heave to and actually quite like it. The added benefit of the CPT
wheel pilot, or any
autopilot for that matter, would be the assistance during tacking maneuvers. This has proven invaluable to me as I
work my way up
wind by myself.
