Thank you gents for the wax tip on the underside of the tubes. I hadn't heard that one before. As to antifouling I use hydrochloric acid 3 or four time a year ove rthe 9 months the boat is on the mooring (drying out) which seems to be enough.

Its a shame because his hull is in good nick, it'll be covered in crap by November. The lazy git never did his last one, you'd have thought he'd have learnt.

It is used on all the quays around the Islands as it breaks down into salt water (convenient eh). It is around 15% conc and applied with a garden weed killer type spray can (replaced failry often about every 2 seasons). Spray on leave for a few minutes and wipe off with a deck scrubber. Reapply to the few patches which have not come off completely. Whole job only takes about 15 minutes 3 or 4 times a season (I recon it would take longer to paint antifoul each season).

I do it on the beach as my boat is on it's mooring now and will be until Oct/Nov. No ill effects and I've been doing it for 4 years.

My boat has Coppercoat. It's expensive and tricky to apply but lasts at least 10 years in the two years since it's been on there's nothing growing on the hull whatsoever. It goes green if you're on a drying mooring like I am or, as mentioned, it goes brown/black when permanently in water. It cost about 900 for a 6.8m Ribcraft including being applied by a local boat yard (recommended).

Might be worth a try if you don't want to spoil your pristine hull.

Forgive me if I am being stupid, BUT, I have been told repeatedly not to use copper based stuff due to electolosis issues if your engine touches the water.
