Anhydrous Lanolin doesn't keep barnacles off prop!!

[Bill Goldsmith]

As an experiment (and possibly following a recommendation, I don't remember) I coated my prop with anhydrous lanolin last spring when launching. Don't do it. By September I was getting a 30% drop in prop efficiency and on haulout there was a barnacle farm growing there. I suppose I should have gone diving and scraping, but September was colder than November in New York!!!

Anhydrous lanolin is a great old fashioned way to lube and protect turnbuckle threads, but it's not a barnacle repellent. Next year I'm going with Capt. "#1" Dave's stove and grill polish!!!!

Bill: I've recently run across a product called Goop, 800-801-8922, AB Marine in Middletown, RI, which I am going to try when my boat is hauled next time. Has anyone out there used it and to what success? Ray

I might try that too but I'm more inclined to go with face mask, fins, snorkel and scraper on a few nice warm days in July, August and September in Oyster Bay!

Humm, Goop, lanolin, stove polish,? How about three coats of Pettit epoxy barrier coat on the prop (don't paint the zinc )then two coats of trinidad on the prop. You must use the epoxy to isolate the copper paint from the bronze prop, but this will last a whole season.

Need something that can resist the "scrubbing" action of the prop thru the water. Have to figure that a 12" prop w/ teh middle reduction ratio (2.62) for the 2GM20F at cruise of 2000rpm, the prop has a tip speed of over 27mph. At max of 3400rpm, the tip speed goes to over 46mph. This is thru water (much thicker than air) that may or may not be clean (abrasive) on something (the prop) that thin, sharp edges. Was going to experiment at one time on Goldsmith's Second Chance, using Mike's idea (only w/ West System) as they use to have a copper additive for the epoxy. But no more.
Captain Stump, can you tell if teh leading edges of your prop have the stove black worn off???
Ray, is the Goop you are refering to, the same all purpose adhesive in a tube that can fix anything and everything???
Warren, idea of scraping is good, if you can see anything. Have gone swimming in the Hudson, off Goldsmith's boat, w/ fins, mask, everything just to do that and could barely see inches in front of the mask. The Hudson has had a turbulent year.

Maybe GE's churning up all those PCBs in the bottom of the Hudson will help with the barnacle situation. Or will that just create new strains? Doesn't sound like a good place to swim once they get started.

Didn't the Navy coat its high-speed hulls with a teflon-like substance that reduces the hull/water friction? Do they still? I'll bet a pint of that would last a long time in our application. I see they are working on antibiotic coatings with NO copper. What do they coat their props with?

Mark,
Over the past year or so I have been observing this great relationship "Yashinsky, Goldsmith and Second Chance" have. Second Chance in some ways acts as a "laboratory" for your boat bettering experiments by which Goldsmith and Second Chance both benefit. I imagine the culmination of all this is some really nice sails together. I hear the water in Oyster Bay has much greater visiblity underwater. Would you be interested in bringing your mask and scraper to Long Island and working on Sine Qua Non! HA!

Here's the short version:

Yes, we've had some great sails, which now include chartering with wives and kids twice to the Virgin Islands, etc......but where did it all begin???

When I got back into sailing in 1998 after a 9 year hiatus, I did alot of research and decided to find a good Cape Dory. I found Second Chance on the hard in the Hamptons and it was the right boat. I brushed up on my rusty nav skills and planned the delivery voyage. I drafted one friend with alot of recent sailing experience. Then I realized I knew nothing about diesels, so I drafted Mark as the third crew member. He had never sailed more than a Sunfish before but knows machinery and was a quick study on marine diesels. Fortunately the Yanmar ran like a top despite an old gunked up fuel filter. 60% of the trip home was under power due to no wind. We had some adventures (lightning, fog), and Mark not only became a sailing nut but a Cape Dory enthusiast and quite knowledgeable, as well. This board is one of the main reasons we both climbed the learning curve so quickly. I've nudged him to look for a good CD of his own, but he says he'd rather tinker with Second Chance. I'm not complaining!!!

One of these days I'll get permission from Soundings to reproduce the article I wrote in the Jan. 2000 issue about the delivery which prominently mentions this cast of characters.

Mark, this is not just an idea, iv'e been doing this for years, only the tips of power craft seem to lose the bottom paint after a season. The west system with copper won't work because it electricaly couples the bronze of the prop to the copper of the paint, two weeks later the copper of the paint is used up like a zinc. This is the answer to avoid diving and scraping. Who wants to dive in a marina? Are you shure your neighbor uses the pumpout station??

I hear GE is into horror film making. "The Barnacle that ate Croton" Wouldnt that be a nice family film.
Mike, the idea was a barrier of plain West epoxy (insulator), then the West w/ the copper additive. Alas, the copper (EPA???) is no longer available. AM NOT STARTING ANYTHING #1, but West does have a graphite additive that produces a low-friction exterior coating. Hmmmm??
And I would not dive at the marina that Second Chance beds down. Have seen films on the water and a storm drain does empty right nearby. Just my nickel.

Bill,

You mean that Soundings got you to give up more than the right to first publish your article? Even Nautical Quartely didn't do that.

You can get copper powder at good art supply stores. It is used in sign painting. You will find many different mixes, some are called bronzing powders. Just make sure you get the pure copper one.

Mike,
Been doing this for 3 or 4 years on my CD-36 using several layers of west epoxy as an insulator and then a layer of copper loaded epoxy. Works well as long as it sticks. This year I had problems with adhesion of the epoxy to the prop. All other years it has kept the barnacles off. It is awfully time consuming. The biggest problem is that it is hard to get the epoxy to coat the sharp leading edge of the prop. See post from last year.
