12.4 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) Check/restoration Preparation of the surface of an already treated yacht Washing of the yacht	The length of the anti-fouling effects depends mainly on the conditions of the waters where the yacht is stationed. 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. 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. Wash at each re-entering from navigation. Only use neutral and biodegradable products in case of dirt stains.
External coated parts	Cleaning	Do not use abrasive or cutting means. Wash at each re-entering from navigation.
Exposed metallic parts	Cleaning	Wash with fresh water and dry with moistened (wash leather) cloth. When re-entering from navigation, wash with plenty of fresh water, especially the handrail base, the windows, the skylights, etc.. CAUTION Also in presence of rusty spots, ALWAYS AVOID using brushes or abrasive rags on metal parts. Such a treatment would scratch the surface, damage the polishing of metal parts and reduce their mechanical features.
