Copper ring report
Last spring I took up a bit too soon on the new through hull nut for
my Knotlog sensor and set it a bit below the surface of the hull. Attempting to make lemonade out of lemons and kill another bird with the same stone while excelling at creative writing by avoiding trite sayings, I cut a ring of copper flashing and epoxied it to the through hull surface thus: http://home.maine.rr.com/rlma/Strider0604.htm#Copper I took the sensor out for the first time today to check it and there is not a hint of slime or growth on it. Last year it had small mussels with discernable shells growing on it by August. I think this really works. I wonder if there is some way to copper sheath a fiberglass hull? I know taking it out more often and putting it in a fresh water with a bit of bleach is another approach but mine was cleverly installed so that the fastest swap with the blank plug still results in a jet of salt water all over the cabin sole and some drawer hardware. It's enough of a clean up that I'd like to not do it more than a couple times a season. -- Roger Long |

Copper ring report
I remember reading of a company that installed some sort of copper foil to
the hull, but that was a few years ago. It wa expensive IIRC, but did last a long time. I have wondered about fitting some sheet copper to the bottom of the keel, because for some strange reason, bottom paint never seems to last as long there. "Roger Long" wrote in message ...

It's enough of a clean up that I'd like to not do it more than a couple times a season. Copper bottoms were fitted to Royal Navy (wooden) ships. Then a scientist came up with an electrolytic method to stop the copper eroding. The Navy loved it. For a few months. They found that cathodic protection saved the copper, but allowed the marine growth to come back with a bang! Brian Whatcott Altus OK |

Hello Wayne, Do you still have any info on the Islander Bahama 24?

In fact is copper-based antifouling not banned, along with everything else? Over here TBT (TriButylTin) was banned for pleasure craft years ago, and I seem to remember copper-based paint was also banned, but could be mistaken. Dennis. |
