    Default Scraping off shell

    Hi All, what tools do you use to scrape off shell on the hull. I was thinking of an ice scraper which I use on my car windscreen.
    thanks in advance. RPP

    If you are talking about barnacles then I find a one inch wood chisel slightly dulled and with the corners rounds works best.

    For less tenacious denizens I use an eight inch slightly flexible scraper mounted on an eight foot pole and used in the water

    TQA's answer is good if in the water. Don't get in the water yourself to do it though because you'll soon be swimming in antifouling soup - not healthy.

    For most people though, its a high pressure hose run over the hull within half an hour of lifting out. Only acorn barnacles will resist this and have to be scraped off. Don't leave it longer than half an hour, because as fouling dries out it gets much tougher to remove.

    I tried that twice (hope over expectation the second time) and the barnacles destroyed the edge on a plastic scraper by about the fifth scrape; it'dbounced over any well adhered ones even on those passes. I generally use metal bladed 50 or 75mm paint scrapers and keep a knackered old 1" wood chisel in reserve for the really recalcitrant ones.
    Hit the road often enough and eventually it will hit you back.

    The boatyard guys at Leros use a metal scraper about 3 inches wide on a pole. Just a bit of flat bar with an edge ground onto it. They scrape tubeworm as soon as the boat is out, hanging in slings, then pressure wash.

    These have replaceable blades. They are sharp so need to be used with care.

    Thanks for the replies. I will be in the water, so I will go for the hand held metal painter scraper.

    If you have easy access to a freshwater estuary then go and anchor there for a few days .... they come off alot easier if they are bathed in freshwater for a while.

    I usually hang a couple of ropes around the hull, bulwark to bulwark, and use them to go down and hanging on when coming out of the water.
    Also, an old t shirt and leather gloves will protect you a bit from scratches.

    On my 40' I usually need two sessions in separate days, I find it to be one of the most exhausting thing to do on the boat.
