Bill,
It is a two blade fixed prop. It spins!
The singing is probably around 400 hz. I might use my phone with the db
app and find what actual frequency it is. It is not a concerning sound,
just wondered if we are unique.
I have thought about a geared feathering prop but the boat bucks always
make me keep thinking. Grace was never raced and has a fixed prop, no
adjustable backstay adjuster and fixed babystay adjustment. I can live
with those though I have thought about prop and hydraulic backstay adjuster.

I don’t think your shaft should be spinning.
Can’t you put it in reverse to stop the shaft from spinning, then
neutral? Or do you not have a folding prop –

Ron,
Yes. We sail with the transmission in neutral and can tell that the
shaft is spinning. We noted it the day that we sailed here home
almost three years ago. We tried to locate the source when we first
heard it but can't really locate the source. She sings on both
tacks. It doesn't concern us that she does this. Just curious if she
is unique.

Does it always happen at that speed; in other words, does a
different alignment of the prop change anything?

Hi Neil
No singing on hull #11. We originally had a 2 blade fixed prop,
and now are running a Kiwi Prop.

OK Mark III owners, our C&C 35-3 "signs" with speeds between
about 4.5 to 5 knots. It is a definite harmonic signing that
I have never been able to isolate. We have a 2 blade fixed
prop and sail with the transmission in neutral. I am not
complaining, I love it when she goes into singing mode. It
goes away above 5 knots and there is no impediment to
exceeding that speed. My question is if "Grace" is unique or
does anyone else show this phenomena?
BTW, we noted no singing when we hit 7.7 knots Sunday afternoon.
