A friend & I bought a Cal 33-2 (Hunt design) last Fall. We noticed while motoring home last October that it pulled to port pretty significantly. Just got back in the water this month and the pull to port seems even worse (though not sure about worse). PO says that it always pulled, and has to do with offset shaft and screw. Prop and shaft slightly off center. But this seems excessive. Now, there was delamination in the rudder. We used the drill and fill with epoxy method (I know it's not ideal but we'll see if it needs a rebuild next winter). When the Yanmar is at 2300-2500 and you let go of wheel, the boat will quickly pull to the left and soon be heading at a 90 degree angle and turning. That kind of pull can't be normal (note: doesn't pull under sail, it's definitely prop related). My question is: if the rudder is a little mishapen, and you could see a bulge in one small area if you really look carefully, although slight, would that worsen the pull, especially if the bulge were on the opposite side of the way it pulls (more resistance there, less on other side...)? Or could there be other causes? Boat does have autopilot, but we've checked that it's disengaged. Also, quadrant and cables look good, have the right tension.
