Anti Foul - Fresh Water

[Jim44]

I have been keeping my 2007 Bayliner 265 on its trailer but have decided to moor it at Aquatcis (Windermere) for the winter.

Question is should I anti-foul the boat?

I am sure I read on here last year that you dont need to in Fresh water but aquatcis recomended that I do.

What do you think?

definitely not - you will get slight slime which easily washes off

Dont bother, we kept a boat in the marina for 3 years with no antifouling. The slime washed off easily each year.

I left a small catermaran dinghy on Rudyard lake for a month Once, many years ago. In addition to the slime, which was easily removed WHEN WET, there were small brown lumps that were a pig to get off. I seem to remember scraping them off one at a time with a knife in the end. Ok on a 14' cat, bit of a pig on a bigger boat.

I would suggest it is probably OK, but do keep an eye open for stuff other than the green slime & weed on the waterline. Take a look at boats that have been sitting there for years, unused - there'll be a few around, check out their gardens!

The windermere water temp over winter and low daylight hours will not give you much growth.

As far as I can tell after may years of trying different antifouls in freshwater, none of them work at keeping the green slim off. The only reason to put antifoul on as far as I can tell is too disguise the green stain, black being best for this. A lot of narrowboats just use black bitumin not antifoul at all.

Thanks for all the replys. I think I will leave it and get the boat pulled out every so often to check for growth.

I have left speed boats in the water all summer without much grief, I think a light acid was used to remove anything that did attach.

One of the marina staff said that it prevents osmosis??

He's talking rubbish. Unless it's an epoxy type anti foul which you don't need for fresh water use. As others have already said no point in anti fouling at all.

Check first with the local water board/environmental officer.

They may not want poisoned water, which is used for potable supplies! Might not do the fish/other waterborne life much good either.
