Was going to do it today but I just hate the yearly application on agent orange to the bottom of the boat!
Sorry Rant over!
I dont mind antifouling at all.Sorry Rant over!
I had to remove one prop shaft yesterday, the prop is on a taper and the sahft is in a tapered hub in the back of the gearbox, what a b
d job.Then i couldn't slide the shaft out so I had to dig a hole in the boat yard...
My dad did the family boat this weekend, normally I get roped into it but I was 'busy' the normal procedure is pressure wash crap off then roller on blue gunk (being careful to cover your head as its not easy to get out your hair!)
That bit is not too bad, the worse is wet and drying the prop and prop shaft to get all the bloody barnacles off!

Not my favourite job either.
Anybody used the copper loaded epoxies instead, like Copperbot or similar on the east coast?
I applied coppercoat in the Spring of 2006 to our 38ft yacht following using Blakes Tiger etc for the previous 9 years, since the boat was launched new in 1997. We are based on the South Coast.Anybody used the copper loaded epoxies instead, like Copperbot or similar on the east coast?
The existing AF was ok in performance terms but was costing about £150 a year in materials alone, as well as lifting it out and putting it back in etc.
I purchsed the materials and manually with scrappers removed all the existing AF by hand over the course of several weekends. (It really is physical work and for £600 I could have had the hull slurry blasted, but you live and learn eh).
The boat once down to the gelcoat was abraded using an orbital sander as per coppercoats instructions and then washed down and allowed to dry.
The application of the coppercoat is a pain in the ass, its temprature and humidity sensative and doesn't like to get rained on until the epoxy has set. My only previous experiance of using it was on a Oyster 55 in Gibralter, (the charter skipper guy there had used it lots and swore by it).
Anyway, you need a team of mixers to keep knocking the product up whilst the rest apply it to the boat. It is important to not try any overcoat to quickly otherwise you will pull the previous coat off.
Performance wise, 15 months after the boat went back in the water we used the sealift in cowes to lift her out and get wash off. There was only minimal slime growth on the boat (it has remined in the water over the winter not used), that was it. The sealift guy said that the growth was pretty minimal and what you would expect for a "decent & proffesional" application of coppercoat.
I am more than happy with it, we pay £150 a year on the sealift now, clean the bottom of for the beginning of the season, change the anodes and check the bottom out etc. With no more AF costs.
We could probably do it cheaper in Lymington on a scrubbing berth with a hired pressure washer ourselves.
It should be noted that it is possible to completely balls the coppercoat application up and it wont work.
The other good thing about jetwashing the hull annually is it activated the copper apparently. Oh the sealift guys will also apply AF is you don't want to do it yourself!
When I get some photos from my brother I will post them up.

There is a product that we used (I forget the name off hand) to remove the antifouling. You paint it on until it stops reacting with the paint, and then it just scrapes off bringing the antifouling with it.tank slapper said:

Tank Slapper, are you on Tenacious? If so we got a few photos of you on saturday going down southampton water!
I wish. No, I sail out of the Blackwater on the East coast, but the boat is on the hard waiting for a new pulpit to be finished at the moment. Hopefully be in within a few weeks.ALawson said:

It would cost about £1000 to slurry blast and Coppercoat my boat, which is a lot cheaper and less hassle than 5 lift outs and antifoul.
