The hull is the structure on which buoyancy depends. The hull can be divided into live work or hull and topsides. The hull is the part immersed in water, and, therefore, is the one most exposed to corrosive phenomena and oxidation of the metal parts, as sea water is an excellent electrolyte for triggering corrosion; for this reason it is necessary to protect the hulls with a cathodic protection provided by the zinc anodes. For best results, it is recommended to install anodes in the exact number and size specified by the boat designer. MTO Nautica, however, supports its customers by also offering them a consultancy and installation service, based on the material with which the hull is built and based on the type of use of the boat, that is, if it is stationary in port or if it has to go out. at sea.
