How do you figure that? The prop is not feathered when the boat is in
the slip. It will still work fine if there are barnacles on it, just
as a fixed prop would. It just won't feather. We HAVE had barnacles
on our prop, and it did exactly as you say a fixed prop would do -
reduced efficiency.
The people whose fixed prop was totally barnacled up (fouled or
fouled??) had a prop that would NOT work even though it was a fixed
prop.
I conclude that you haven't really had much experience with feathering
props.
: a fixed prop would have its' efficency reduced, but would still work. As far as speedometers: they can be removed from inside the boat and cleaned. Depthsounder transducers will have to be dove on, but may still work until totally fouled.
Yes that's what I said. The speedometer can be removed and the gunk
or whatever removed without diving (usually). And our depth sounder
transducer was completely covered with barnacles. The prop however
was quite fine.
>I believe in Murphy's Law. Having something that you can't see, with lots of moving parts, whirlling around underneath your boat is inviting disaster - based on Murphy's Law. It is not for me.
There aren't lots of moving parts. And it doesn't 'whirl around' any
more than a fixed prop does - actually it whirls around less - that's
the point.
I am not telling you that you have to get rid of your fixed prop.
We have a feathering prop which we did NOT get for increased speed
under sail or because it would back better, although those things
occurred as a side effect.
We got it primarily so that the drive shaft wouldn't spin with an
excruciating amount of noise when we were under sail.
One person with our type boat/transmission puts a vise grip on the
shaft to stop it rotating, but while that is the simplest and lowest
cost solution, it is not one I'm willing to implement. We can NOT
stop the shaft rotation by any manipulation of the gear shift, putting
it in reverse or forward or neutral has no effect on the spinning of
the shaft.
