What I understand from any of your postings is that you are incredibly
insecure, misinformed, and HAVE to have the last word.
My point was, Rosalie had performed her own test on drag with prop folded
and unfolded and stated her results. You're pointing out that her prop was
turning and creating drag really didn't support your fantasy position in
this discussion. My fixed prop turns too, when in forward, reverse, or in
idle and sailing. In fact, the only time it doesn't turn is when the boat is
dockside. Amazing, huh?
I've avoided responding to your posts for years, but couldn't when you
lamely tried to make Rosalie look bad when all she was doing was
participating in a discussion (which she understands better than you do).

Rosalie, your prop was also turning while you were running the engine.
that
alone is one hell of a drag.

You will definitely will see a decent speed improvement under sail

a
folding prop. Depending on the prop you buy, you should see better
power/control in reverse too. They are very reliable now, so I don't
think
that is a down side. The biggest downside is their cost. I have a Max
prop
and think it great.

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.


We have a feathering prop (vs a folding prop) and we do get an
increase of about 1/2 knot under sail, and it also backs better under
power. I haven't tried to quantify the backing under power - it is
just what we feel.

Disadvantages are - you lose a bit of power forward because the blades
are flat and the prop takes a bit more maintenance than a fixed prop.

[We were sailing but had the engine on in neutral so the prop was not
feathered - we were running the refrigeration- and when we had
finished that, we turned off the engine and feathered the prop, and
our speed increased 1/2 knot - same wind and current. Now I know this
is not a completely scientific test, but it is significant to us.
There are also people in our group who did tests with a fixed prop
over a measured course, and then did the same tests with a folding
prop over the same course and found a similar result.]
