The biggest factor is the interaction of the prop with the hull.

My props are Left-Hand, two blade folding. There is virtually no propwalk. I'm quite
familiar with the phenomenon because my old Nonsuch would walk hard to port, as would all
the single screw boats I've driven.

I was under the impression that a major contributor to prop walk was the angle of the
shaft; thus, if its horizontal, the affect is greatly reduced. If this isn't the case,
what does cause it?

Neal really doesn't understand, even though I explained it fully. He'll
figure it out and
come up with a creative way to cover his ignorance!

BTW, I get virtually no prop walk - is that because the shaft is horizontal,
the blades
are flat, the keel is long, or a combination of all three?


None of the three SHOULD eliminate "prop walk", singly or in combination ....
G you don't have Kort nozzles, do you?
To be sure I'm thinking correctly, both your props are right hand, folding? (I
have no experience with folding, so I don't know if this may be a factor).

When backing, your boat, should want to back to port, as Neal said, once you
lose steerageway .... does it? (assuming two right hand props ... I can't
remember if you said right or left).
