Well, golly, gee, Doodles, I'm impressed. A simple direct answer to a
simple direct question.
Simply stated, for those who live in the real world of boating and
propellors, when discussing "Feathering" props with Doodles, keep in
mind that if there is any curvature or cupping to the blades, then you
will have to determine and use the "Doodles terminology" for this blade
and condition, as it does not fully meet the requirements of "Doodles
terminology" and is thus unacceptable usage.

So,Doodles, what you are saying, is that unless the blades are totally
flat, the term "feathering" can not be used?

I'm going to re-power soon and am also going to get new shaft and prop.
It seems that in my boat class (Westsail 32), some people are going
to folding props to help speed under sail.
I'm for increased speed, but also want reliability. My current bronze
propeller is pitted and old. Every time I turn around and look at it, it
is full of sea growth. That makes me think I'm getting poor performance.
So, I'm for an improvement, but I am unsure of what kind.
Any opinions from boaters that have encountered this situation would be
appreciated.

Thanks,

ANY modern prop will improve your performance under power, forward and
reverse. Technology has improved in 30 years.

A feathering prop can drastically improve sailing enjoyment if you don't
bother to park your prop behind the keel. Your Westsail may not get the
improvements we get as we're lighter and cleaner, but we pick up .5 to
.8 knots when I remember to stop the prop, which has us sailing more
than we used to.

Windward performance improved, allowing us to get a bit closer to the
wind.

We also get more comfortable sailing past hull speed, but the "wetsnail"
doesn't have a hullform that allows much of that.

We don't have a Westsail of course, but with enough wind, we've gone
faster than hull speed a couple of times. What do you mean by getting
more comfortable?

So what? feathering a prop doesn't require that there be *no* drag, it's
a way to reduce drag, not eliminate it.

The autoprop blades rotate to parallel to the axis of the shaft, how is
that not feathering?



The blades rotate until they are inline with the shaft axis, how is this
not feathering?

take a look at the blades. they rotate and thus *reduce* drag, but they
certainly don't "feather".




I have, the blades rotate to line up with the axis of the shaft, how is
that *not* feathering?

no it doesn't. take a look at those blades and you will understand, probably.
if not, ask any passing yardworker or dockboy to explain it to you.

jimmy, look at the blades. if you can't see what they look like and what they
do, look at a prop that feathers and you **should** see the difference. if
still not, ask a dockboy to explain it to you.

G Knowing the "term" correctly, is one thing. Being able to apply the
term to various situations seems to be beyond your abilities.
I'd hate to see what you'd do if I sent you to stand by the "forward
