Abstract (en)
A method of protecting a boat hull comprises deploying a protective envelope around the hull and treating the entrapped water to inhibit the action of marine organisms. When it is desired to use the boat, the envelope can be retracted to an unobtrusive position in which it occupies little space and its exposure to marine currents is minimal. Retraction and deployment is effected by folding a frame or support on which the envelope is mounted, and/or the envelope itself. During storage of the boat within the envelope, the entrapped water is tested by a probe and the amount of treatment agent needed to neutralise the marine life is determined. This precise amount is added to the entrapped water, whereby the latter is rendered neutral with respect to the hull and is likewise harmless environmentally when released upon retraction of the envelope.
