So you're talking about pitch of the prop as inches per revolution and not
pitch as angle of the prop shaft?
That's going off on a tangent as those talking about pitch angle in this
thread are talking about the angle of the prop shaft from the horizontal
or at least that's the impression I got.

You are confused then. Propeller pitch is the distance a prop would screw
itself forward in one revolution if there was no slip.
I noticed from your earlier post that your 'bluewater yacht' has an outboard
on the stern. ROFL




I thought it odd also Edgar. Every mariner worth his salt knows that
propeller pitch refers to the distance the prop would travel through the
water under ideal conditions, usually expressed in inches per
revolution, the use of degrees is only for academic purposes as the
angle of the blade is not uniform from hub to tip in normal
applications. Shaft angle should be rather self explanatory.
