Which Antifouling? Drying mooring...

[Trevelyan]

Hi all,
I'm facing the interesting decision of which anti-fouling to use. The factors are:
-22ft sailing boat, lift keel
-drying mooring (medium to hard sand), boat not put on legs so will 'fall over'
-boat over wintered up creek on legs, only floats on spring tide (i.e. hull stays dry for several days in a row)
-would like to anti-foul in the creek ideally.
-boat is in a fairly low fouling area. Don't really get any weed or slime, just a bit of barnacle type growth.

Any pointers gratefully received!
Cheers
Trev

Do you really need to antifoul at all? Maybe just a scrub down from time to time?

Well, I had wondered that one. The existing anti-fouling is pretty old (previous owner) and flaking in places so probably needs to be done for cosmetic reasons. Perhaps though a hard/long-lived anti-foul is the way to go and it might last a few seasons with the odd scrub down? Trev

My boats have always lived afloat, but the impression I get is that most people around here (the Solway) with their boats on drying moorings treat the antifouling as mostly cosmetic. I think it has to be hard, 'cos the soft/eroding stuff wears away very fast.

Tri lux 33

Trilux 33 looks good from the literature on the net, although quite expensive! Will it really last more than one season? The boat lives up a creek on legs in winter as high as I can get it on a spring tide, so on neap tides the hull doesn't even get wet - will non-immersion of the antifoul in winter be a problem or will it stay good?

The boat didn't really seem to have much fouling at the end of this season, but the existing antifouling (previous owner) is beginning to flake in places, so a bit of debate as whether I do it or just leave it alone... On the other hand could I get away with something cheap and cheerful - e.g. cruiser uno...

If you read the instructions on eroding AF it says that you should immerse within 3 months AIR. I would imagine the same would apply after drying out.

So do I go cheap and use cruiser uno and only get a season out of it, or go Trilux 33 and assume (hope!) I'll get a couple of seasons out of it...

Cruiser Uno isn't that cheap!

If you look up Premier Paints website they claim to be very cost effective. if you would be so good as to try it out and then report back, that would be great. Their semi-hard antifoul (claimed to be equivalent to Micron) sounds good.
