Suggestions: Anti foul protection for prop and shaft

My CAL229 as well as many sailors on LI Sound have the yearly battle of barnacles and other growth on the prop and shaft. Most have resigned themselves to short hauls or "going over the side" weekly or bi weekly to keep it at bay. There's polish and multiple wax coats, hard AF paint, soft AF paint, outdrive AF paint....you name it- it's being used....with many still going over the side. I'm kicking this out to group to solicit any tricks that you've found to work. Understandingly the problem with the type and level of growth and probably the solution is marine micro environment sensitive. Still, it will be good to hear from others on what they do.

Last year we had a bumper crop of barnacles in North Cove, Old Saybrook. Before launch, I sprayed zinc onto the prop, 3 coats, and left the shaft uncoated as a control. When hauled in the fall, the shaft was completely barnacle covered, the prop was clean. I was convinced !

I have the same problem in San Francisco Bay. Here are a couple thoughts: A: For fixed props I have read about some boaters having success painting the prop with bottom paint. This way you only get the fuzzy moss & not the tunicates, sponge & my favorite the barnacles. B: I have a folding prop & this is what works for me both on the shaft and prop: I turn over the engine & put her in gear every week whether I go out or not. That does the trick. Even if you have a fixed prop, you may want to do this to get the shaft. I clean my own hull & do zincs, and I can tell you that running the engine and putting it in gear while moored one a week will keep the barnacles & their buddies down to next to nothing. A couple months without doing this and I have enough barnacles on the prop that it affects the efficiency. I have read that this type of growth on the propeller can cut propeller efficiency down by 50%. Be sure you moorings are in good shape before you do this.

Will the one time a week start motor and put into gear work to remove all growth without bottom paint on prop and shaft?

Does for me. I do not have any anti-fouling paint/spray etc... on my shaft or prop. You still get *some* growth, but it does not accumulate & the few barnacles you get are pretty small.

I too keep my boat on LIS (Western end) and have battled the barnacle for many years. I tried bottom paint (hard and ablative) with no real success. For the past several years I have used Anhydrous Lanolin on the prop and shaft. It lasts for a good portion of the season and does a good job. The little buggers can't get a foothold on the lanolin. But it wares off and I need a bottom cleaning by August. This year I am trying Pettit Zinc Coat Barnacle Barrier. I'll let you know how it works.

I've got two boats, both in the Great Lakes and both with outboards in wells that are immersed all summer. Well, last year the Cal 20 had an outboard only for the last month because it was waiting for me to fix it all summer, and it was more fun to go sailing than tangle with outboard problems. Davis makes some goo that you rub on the surface to be protected, and that is supposed to impair adhesion of the various critters. When I got my new outboard for the other boat (used, actually, but pristime) I did not want to start painting the aluminum lower unit with copper-based paint to make a battery. I've been using the Davis goo on it. That boat lives in a freshwater marina slip, so the water is warm and stagnant. It's on a river that is a major agricultural drain, so it's fertile. The boat sails on weekends, so there's lots of sitting time for flora & fauna to take up residence. The Davis goo does not work perfectly, but I think it helps some. The instructions call for periodic brushings during the season, but I haven't done that (probably should, with some sort of soft sponge or brush). At the end of the season, the power wash does not remove all the stuff. It does remove most of the zebra or quagga mussels and most of the masses of green stuff. It leaves a coating. Recently I've been using vinegar to wash it off, and If I do it while the stuff is still damp, it helps a lot. The power face of the propeller, the face that pushes the water, has a lot more accumulation even after the power wash. I take this to indicate that the goo washes off that face by hydraulic pressure, whereas the other side of the prop blades is much cleaner because the goo remains on the surface longer. On my Cal 20, I have used a tributyl tin antifouling paint on the outboard. Lately I have been ignoring it because the boat is in a fairly non-fouling environment (on a mooring in very clear, cool water). I bought a few cans of the primer and paint before they were phased out. I'm not sure if the stuff is available to the consumer market any more because it's highly toxic to marine organisms, including ones not trying to live on your boat.
