13.4 Hull maintenance

Component	Maintenance	Notes and precautions
Bottom hull	Periodical cleaning and check of antifouling treatment (as required according to stationary area, but at least every three months)	The length of the anti-fouling effects depends mainly on the conditions of the waters where the yacht is stationed.
	Check/restoration	CAUTION When removing the old antifouling, do not use sandblasting methods, as this may damage the gel-coat surface and the anti-osmosis resin applied by the Manufacturer. As suggested by the antifouling manufacturers, use paint removers or, as an alternative, wet sanding. The Shipyard uses high-quality ant-fouling paint and applies two layers.
	Preparation of the surface of an already treated yacht	CAUTION Bad maintenance condition (barnacles, etc..) may cause cavitation and damage shaft, rudders, propellers, etc.. CAUTION Small areas of paint may peel off from the propellers even after a short period of operation.
