A Photo & Discussion Forum for Wharram Design Enthusiasts
A number of years ago I newly anti-fouled my Tangaroa with a Jotun antifoul in Thailand. It was brilliant. After almost 2 years, there was a slight slimy sheen just at the waterline, but the rest looked as good as new. I know why...it was the really good stuff that was banned a few years later due to the high tin(?) content and nothing would survive on it.
I launched my Tiki 21 in October last year, and was shocked to see the growth beneath the waterline in just 4 months. A quick scrub over the weekend removed loads of shells which had firmly stuck to the hulls. I'm now considering pulling the boat out the water in the next couple of weeks, cleaning it, re-antifouling and relaunching.
I admit, I had the wool pulled over my eyes when I bought the paint, being told it was as good as the International product, but half the price. Yeah right! I assume over winter the hulls will be upside down and I'll be scraping back all that antifoul, to recoat it with the "good" stuff.
On another forum a number of years ago, the discussion surrounding antifouling became quite interesting as people started to add their "recipes" for what worked. I can recall one guy adding bleach before slapping it onto the hull. Another suggested curry powder, other copper filings etc etc. I never tried any of these myself as I did not own a boat at that stage.
Does anyone have a tried and tested "brew" that works? Or is it best left alone and applied unaltered? What is a suggested brand, and how long can I expect to have that on before re-coating? Will be good to hear any suggestions!
By the way, you can still get the tin based antifoul paint here in Bahamas. Ann and Nev
