Really? I never get barnacles on mine. Boat builders used to put tin

barnacles wouldn't grow on those. Today's bottom paint is copper
based. Isn't your prop made out of an alloy of copper and tin?

I've never seen any barnacles on any props of any boats in my marina.
No barnacles. Not one. No zebra mussels either.


When we were still in Michigan, even using a copper based bottom paint
(VC 17) and having a bronze prop, we still had a few zebra mussels at
the end of wach season...


I use VC 17 and never get zebra mussels where it is painted. Only on
places where there is no paint, like at the top of the rudder, or on
the plastic thru-hull fittings.

Barnacles won't grow on a prop that gets run every week or so.


I wish that were true. My boat gets launched in April. It gets "run"
2-3 times a week. By July I have a coral reef on the prop and shaft.
What I cannot figure out is after I clean everything off the first
time in July later dives under the boat and after the water has been
warmer for a longer period of time I hardly have any growth on the
prop. What's with that?

No, barnacles will grow on copper and tin. Metal helped against barnacles,
weed, wood rot, etc., but the real reason was to keep sea worms out of the
wood.

I agree with that.

Bottom paint is copper based to keep off barnacles. I never get any
barnacles on the bottom of my boat.

What's good for 'bottom painting' a prop?

I just 'filled up' yesterday, first time this season, took
all of 6 gallons.

So I guess 'just sailing' doesn't keep the critters off the
prop?
