Antifouling & Tube Protection
I know there have been various threads on antifouling RIBs and I've waded through a few of them but couldn't find much about protecting tubes against growth. I have a Ribcraft 5.3 and the aft few feet of the tubes sit in the water when the boat is tied up in the marina. After a summer of lifting every 4-5 weeks I've decided to antifoul it for next year, even after 5 weeks in the water it's a 2 man job for at least an hour, often longer, to get it clean again. The yacht I race also has no antifouling on it either but it's lifted every week and has about 5 people to scrub it, so it's with a slightly heavy heart that I've decided to paint my lovely white bottom on the RIB.
While it's all well and good antifouling the hull, probably with Blakes Hard Racing option, does anyone have any tips for keeping the tubes which won't be antifouled somewhat growth free?? Is there any form of polish in particular, or some kind of wax or even grease of some sort that can be applied to stop the little feckers clinging on to the tubes??
