Yeah, what Rob says. Lots of factors can make a boat faster on one tack than the other.
I've never even come close to assuming Touche' was square, symmetrical or otherwise perfect. Our boats are imperfect, particularly the older models. In addition to rig alignment and tuning, weight distribution, etc., unless you've had your keel and rudder verified to a template, I strongly suspect one tack will be favored. Dennis C.
