Re: Prop and Shaft Barnacles

Re: Prop and Shaft Barnacles

Last year this was a major issue. So scraped then hand sanded down to automotive paper. Then two coats petits spray and two coats very thin layers of petits water soluable bottom paint. Works so far. Boat is run near daily for a week or two. Then sits for about a week ten days. In marina on slip with out much current.
Big disadvantage to prop speed is need to get back to bare metal before each reapplication and expense. See variation in effectiveness if done by yard or owner. Petits spray seems idiot proof- just right for me trying to DIY as much as possible.

Amazing to me that anybody would haul a boat to clean it, especially in an area where hull cleaning is an actual industry, like the Chesapeak Bay.

The marinas are catching on it seems and offering fairly cheap quick hauls around here, especially if you pay cash

I had always kept our boat in a working marina so a quick haul was easy and gave ME the chance to inspect the boat. When I moved to a club with no haul out facilities I started using a diver. Granted, I have only used one diver so far...

So before our trip I had the diver come inspect and clean the haul. Then after he came about 10 days later I decided to have the boat hauled so I could adjust the pitch on my prop (Autostream feathering prop), the marina owner almost insisted I do this instead of diving myself, so I followed his advice (he offered me a fair price to do a quick haul)

Sure glad I did because what I found is the diver didn't do as he said he would. Barnacles on the shaft and prop. Fine hair like growth all over the hull except near the waterline, and areas that needed some paint...point being I was very disappointed in the services provided by the diver. Which made me rethink the entire diver thing to be honest. On the Chesapeake bay the reason I would hire a diver is because I don't like to dive on a boat when I can only see a foot if that, creeps me out.

I am certainly not implying all divers suck as much as this one, but if you don't check for all we know they're having a beer in the cockpit and charging me $100 for it. Not saying of course this is typical, but certainly makes me skeptical and if I hire a diver again, I will certainly check their work.

Re: Prop and Shaft Barnacles

Well, in this Bay Area, boats need cleaning every couple of months. Hauling for routine cleaning every time it needs it just ain't done.
