Lower that paddle wheel into the water, until it is just beneath the
water .... bet it will still pull to the right, because the blades on
the upward part of the rotation will be lifting the water and basically
throwing the "push" away (into the air) i.e., they'll be pushing, but
not at the efficiency of the blades on the downward turn.

Being old and senile, I have to work things out with a mind
picture.

Re prop-walk...if I have a prop with flat blades aligned fore
and aft, I essentially have a "paddle wheel". If I turn the prop
clock-wise (as viewed from the rear of the boat), I'd
expect the stern to go to the right. Reversing the direction
would obviously make the stern go to the left.

If I re-pitch the prop so the flat blades are at right angles to the keel,
(cross-ways), I'd expect a bit of froth, but not much in the way of
stern reaction.

When I consider a *real* prop, the blades are aligned between
the two extremes above, and I'd expect the stern reaction to
also be between the two extremes.

sherr, did you really wish to say water displaced one way is more important
than water displaced another way?

You did. okay, you have just invented the Perpetual Motion Machine. Don't
forget the Patent Offices requires a working model before you submit an
application.

nah.

Nope....and didn't, neither.

jexer, did you really wish to say that, that paddle wheel (just below the
surface) was working in a solid medium of water through all angles of rotation,
thusly exerting the same amount of push/pull on a hull, at all angles of
rotation?
You did ..... interesting....

s'posed to use wid der jexer, errr, jaxer, errrr jaxass.....whatever)

sherr, ever hear "For each action there is an equal and opposite reaction"?

if you have, why do you seem to think it doesn't apply underwater?
