The discourse this Spring about stove black being an effective barnacle preventative, albeit convincing, by my direct experience turns out to be a lot of bunk -- or LIS barnacles are too smart for it. I am now sporting a good two inch thick coat of barnacles on the prop. I should have guessed that if it were any good, yachtsmen through the centuries would have been using it.
Did anyone else try it?

Stove black--BAD!

Don,
I tried it too, but I haven't inspected the prop lately. That is probably a good idea before we head off on our next trip. I'll let you know what I find.

Re: GREENWICH COVE!!! No wonder! ! !
Captain Sargeant,
Sorry to hear of your foul experience. Do you EVER take that vessel away from the dock? If so, the problemO must be the critters living in the cove. What DO you people dump in there anyway? I use the black stuff up here in Noank, and the prop is clean. 'Course, Hanalei is at sea at least twice each week, so that short run of the engine may help. I've used it for the last two years and have had very little fouling, if any.
Ah, well, fall is coming and haul out is next. We can discuss this all winter. I'll let ya know how many critters I have on my prop later....

Re: Stove black--BAD!
I tried Stove Black also -after all, why not? When I applied it, I thought it too watery, but persevered with several coats. After launch, when the engine started for the first time, I looked over the stern and saw a gush of black water and thought, hummmph, so much for that. This year, the barnacle seem less prolific than last year, but I have nevertheless had to dive the prop. I'm not sure whether Stove Black had anything to do with this year's improvement, or whether last year was particularly bad.
Next season I will try beeswax. I'm told it has the virtue of underwater application. Then again, we are all told many things

Re: GREENWICH COVE!!! No wonder! ! !
Dave,
We do flush with Perrier, here in Greenwich, but I would have thought less use of the engine would have removed less carbon, but your thinking is the the barnacles wash or slough off, when the prop turns, because of the carbon? Interesting concept. I haven't used the engine more than three times this season and then for only a few minutes each time. Coquina likes to sail off and on her mooring.
BTW, I spent a few days a few years ago at a company sales meeting at the Montauk YC. Excellent place fer sure. But still too far for many of us still employed westerners.

Re: GREENWICH COVE!!! No wonder! ! !
Don,
Couldn't you join the fleet from say Greenwich to Saybrook, stay overnight there and then broad reach to Montauk? Just a thought. I would think that anything put in the water anywhere on this coast and not turned over more than three times a season, would grow not only critters, but some pretty good mussels, spanish lettuce and other things too. Maybe a chisel and a pot of hot water with some broth and melted butter would be better!

Re: GREENWICH COVE!!! No wonder! ! !
If Hanalei is out twice a week, this explains a lot. The prop action supposedly spins off the slime which is what attracts the critters in the first place (their equivalent of grub). Another story? 'Can't do any harm to try it!

Re: Stove black--BAD!
I heard or read somewhere that anhydrous lanolin on the prop would keep the critters sliding off. After 6 months in warm Florida canals I can say difinitively... it does not make any difference. The barnicles like my prop just as well slippery or not.

Just a thought...
Although my CD25 is outboard powered. I used a product this year and I can definitively say NO GROWTH on lower unit..including the prop. The product is TEMPO clear anti-fouling. It is a 2 step process and when done and cured feels like a clear teflon. I am sure it has some killing properties but it also bonds to the metallic surfaces which is good in the case of a high movement item like a prop. Might give it a look see. Runs anywhere from $20/$30 for a 2 step kit. Primer then finish. It is clear so you won't destroy the beauty of a highly polished bronze prop..divers and sharks will love you.

Re: Stove black--BAD!
STOVE BLACK....huuuummmm.
lets see...how many things I did put in my propeller thru-out the years...
maybe a dozen or so...non of them worked very well for different reasosns...and some of them may even be harmfull and eat away the metal to the point of destroying the prop beyond repair...
so when I got my boat COMPINCHE about 20 years ago I asked the dealer how about a zinc anode in the prop shaft he said no need for it...
so I went and got a zinc collard and put it in...great now I am all set...
next year with a fair amount of barnacles...I checked with the same good folks that sold me my new toy and again told me dont put a zinc no need for it the bronze shaft and prop takes care of itself and barnacles dont like it....guess what...I still did not believed them and got one of those things that screw at the end of the shaft like a acorn shape nut...kind of expensive but what a heck looked great and I new this will take care of the criters...
few weeks later I had some friends for a sail and let the mooring line go off...now at idle on forward and drifting sideways and somehow backwards like like one of those kids ballons with a happy face...anyway more power but no joy...great must have lost the propeller and before I runned aground dropped my lunch hook and with water in the sixties dove under to see what was going on...looked at the prop and it looked like a pineapple...well with my rigging knife in mouth doved again and scrapped them criters till prop was freed of them...
interestingly next week I careened COMPINCHE and removed what was left of the pitifull zinc anode...nice try anode...never again will I not listen to experts unless off course I feel strongly as I did back then and put another zinc into prop shaft...I also noticed shaft chewed up in area by cutlass bearing...
since then prop and shaft been changed and have not used anything on it...now it remains pretty much free and clean...
but again seems that the key to a clean prop and bottom may very well be moving your boat and sailing as much as possible...
by the way Don ... my boat is moored across the LIS in about the same conditions as yours and I dont have the time to sail every other day.
hope this is of some value...and like to hear if any one has the same approach to this constant problem...

more thoughts...
Mike,
But do you flush with Perrier?
I never had more than a few barnacles on my old boat's prop. And no anodes either. There must be a connection.. But CD's bonded system requires an anode on the shaft doesn't it? (mine's stainless) The anode (Perry nut) lasts only a season on my CD, the old boat never saw any corrosion on the prop either. The TEMPO 2-coat system works well for my neighbor in the boatyard but he has no zincs either.
Farther along we'll learn all about it!
don etc.
