Re: Boat pulls to stbd moving fwd under power

The oddity is that this would be a 'new' problem.. not something that's always been there. Plenty of spade rudder boats have a "power pull" one way or another when the propwash impinges on the 'balancing tab'.. this kind of nuisance goes away under sail, of course.

Not sure about the IP rudder but if it's balanced that might be occurring.. but then it shouldn't be a new phenomenon unless the prop or something else has recently changed.

Having had a Max prop apart I doubt the pitch could 'shift' itself.. not without some highly noticeable rattling, vibration and other obvious goings-ons....
