Periodically check that all equipment and machinery containing water is protected with the correct proportion of non-toxic antifreeze.
If the outside temperature is below or close to 0°C, the fresh water and sea water systems run the risk of freezing.
Piping and hoses may break from freezing and this could lead to sinking the yacht.
The systems subject to the risk of freezing include, but are not limited to, the engine and generator sea water and fresh water cooling systems, the water maker system, the fresh water system (cold and hot water piping, pumps and tanks), the windscreen washing system, the toilet and waste systems (piping, pumps and black water tanks), the air-conditioning system pumps and piping, all sea water pumps and piping, the icemakers and refrigerators, etc..
For more information on the maintenance and service requirements of your yacht and its equipment, and for special information about maintenance with cold weather, see the sections in this manual that make reference to the single components, devices and equipment, but especially consult the User Manuals provided by the Manufacturers for specific information.
