My advice would be to start off without antifouling and see how quickly the weed grows. When there is a bit on there, lift it out and jet it off.

See how you get on doing it this way. It may be that the expense and hassle makes up your mind and you decide to go for antifouling. I *was* going to antifoul but I am glad I didn't. Jetting off once a month (I must own up and say the marina staff do it) keeps the weed down.

I think it a shame if you do have to antifoul but it might be the best solution if the weed is proving a big hassle.

My Rib is in the QE2 marina in Guernsey and if it is staying in for most of the year antifouling is essential. Thw water in the marina is warm and full of life. Also depending on which way your mooring is facing will determine how much growth you get. Spend a bit of time walking the pontoons looking at differentribs/boats, you will see the difference between antifouled and not antifouled.

Many thanks everyone
As suspected, I may have been fed some perhaps slightly 'askewed' info there, as the chap concerned hasn'r been over here very long and is used to colder waters (where perhaps the weed growth is less significant).
I shall anti-foul and I do like the sound of the hard white, which would be ideal and less obvious.
My current boat is antifouled with international and not a sign of growth - aprt from the stern drive which has bloomed into a venerable little underwater amazon. Still, nothing a good blast at 30 knots won't sort out!
Good point on the direction facing Tony, I'll have a good look at that next time I'm down on my berth (mine is south facing which may account for the weed on the stern).
Thanks for all your advice, it is appreciated!

I spoke to the techy chap at International Paints. He suggested:

1. Key up the bottom with 180 grade sandpaper;
2. Apply 2x coats of Gelshield 200;
3. Apply 2 x coats of Trilux (white).
4. Burnish, if required.

But Trilux is crap, as in completely hopeless as its only a medium strength. Unfortunately its one of the few antifoulings that can be applied to Aluminium. Two years ago I painted the stern drive with it only to have weeds growing within 8 weeks. Lifted the boat out and International came and visited. There solution was to give me another 3 litres of the stuff in compensation, hmm thanks.

Internationals Ultra or as previously mentioned Blakes Hard Racing are known good antifouls although I am currently using VC Offshore with excellent results, just wish there was something stronger for stern drives.

Cue Codders and his experimental and secret Vindaloo powder for adding to B&Q emulsion paint

Thanks Andy/Pete
I'll wait until it's craned out to have a darn good go at it. I have had a few suggestions from Lanolin (but more suitable to a more leisurely turn of prop methinks) to CopperCoat.
Not sure but I may well try some hard compound antifoul like Blakes next year (but make sure I don't paint over the anodes!).
Cheers for the helpful advice guys.
PS - Anyone from RIBnet forum in Guernsey, there are RIBNet stickers available at Micks Fishing free without the need for any purchase (natch).

Just don't rush into antifouling her would be my advice. See how fast the weed grows.

I use VC and Blaes hard racing both good get the primer cvoat right and you are good for the year. We used VC tar as our primer coat ( I think)

Some bright spark left our dive club rib in Portsmouth harbour for 6 weeks one summer. I and several other members had to spend a weekend cleaning the crap off.

I know Carly doesn't antifoul his little speed boat incase he looses 1/10th of a knot off the top end so spends his spare time polishing it instead. Also Nautibouy bought a floating dock the size of an aircraft carrier to park his rib on top, out of the water, but for those that just want to step on board, turn the key and go then a nice coat of International hard antifoul will keep the wee beasties away afterall all the other boats in your marina will be antifouled, why not a rib.

Be wary of "snake oil" products claiming they will replace antifoul paint btw, some horrible photos on here showing complete failure.

peter,peter,peter,whats the word im looking for ,ah i know,happy slaping,you cheeky bugger. anyway have mine lifted at the moment by sealift in cowes,every 6 wks or so(less this time of year) hull is like new after a pressure wash and scrub,nice bloke, and after you have been a few times will start doing some deals. thats the plan at the moment ,the ideal situation would be for naughty boyo to sell me one of his plastic lego sets at friend prices
