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.

Wilbur Hubbard
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.

See definition 8 please:

2pitch vb 1 : to erect and fix firmly in place ~ a tent 2 : throw, fling 3
: to deliver a baseball to a batter 4 : to toss (as coins) toward a mark 5 :
to set at a particular level ~ the voice low 6 : to fall headlong 7 : to
have the front end (as of a ship) alternately plunge and rise 8 : to incline
downward : slope


Now I know you're being obtuse!
