Prop walk is the "sum" of a number of factors - prop rotation (left or
right), prop pitch, shaft angle, vessel trim, wind, current, hull form.
A right hand prop, SHOULD, back to port .... a left hand prop (G fixed
pitch), SHOULD, back to stbd .....
BUT, results will vary for any and/or all of the reasons above, and in
addition, whether you are all ready turning and/or have headway or sternway.
When you start out on a boat, figure the "SHOULD" first, then standby to
learn the "oops" and vagaries, that WILL apply due to any of the
factors, listed above.
Try not to think of it as your enemy and learn to use it.
