When to renew antifoul ?

[Swg]

Hello, I was lucky enough to get a new, factory anti fouled shrimper in August 09. She has spent extended seasons in the sea, winter ashore. Just lifted out today and she's weedy and barnacled in patches. Both came off very easily in 10 mins with a light scape. The anti foul looks good and intact. So, barns and weeds stick on, but not tenaciously.Should I re- do for the forthcoming season or save the money and fishes and give her the odd scrape in 2012?

Dont Shrimpers come coppercoated as standard ?? ------I maybe wrong tho'

If conventionally antifouled I would find out what antifouling was used, if possible, and apply that again after thoroughly scrubbing off.

However factory applied Coppercoat is one of the options from new. It sounds as though yours may be Coppercoated.

If it has been Coppercoated cleaning off any light fouling should be all that is required now or for a good few years to come.

Mine gets done every 3-4 years, but I use a commercial antifoul (available to all on Ebay), but if I lift her out and clean her she'd get another coat, doesn't do any harm its out anyway. I know the local boats get done every season but they don't go far and use racing antifoul which it appears rubs off in six months.
