14.3 LONG YACHT INACTIVITY
The following section provides a limited, general guide to help you
understand the ordinary maintenance that should be carried out when the
yacht is decommissioned for
any length of time.
Check carefully the instruction manuals of the single devices.
As with all maintenance and service requirements on your yacht, only
qualified and/or certified technicians should be employed to carry out
these activities.
14.3.1 General Long-term Lay-up Guidelines
− Wash the yacht with fresh water.
− Prior to land storage, the yacht’s bottom and all underwater gear
should be pressure washed to remove marine growth and fouling.
− Inspect the outer hull and all components: propellers, anodes, shafts
and strut supports, rudders, trim tabs, fan-coils, thru-hull fittings and
sea valves and bow thruster.
− Check all lights on deck, the flybridge and the radar arch.
− Clean all staterooms and inspect all storage areas; remove all trash
and garbage.
− Remove all flammables, e.g., paints, fuels, cleaning products, rags,
etc. Dispose of these materials in a toxic waste facility.
− Check all hatches, seals and closures and lubricate.
− Clean all fan-coils with a vacuum cleaner.
− Check all systems and fastenings on the yacht to avoid damages.
Store the yacht in a sheltered place away from wave action and high wind
exposure.
If the yacht is stationed outside, cover it with a waterproof sheet placed
in such a way that allows ventilation. Otherwise the formation of mould on
the yacht surface could be helped.
14.3.2 Engines And Generator Lay-up
For specific directions for service to be performed prior to an extended
period of inactivity. Perform all the engine manufacturer’s
recommendations for engine lay-up in accordance with the engine
service manuals. These activities include, but may not be limited to,
servicing oil and air filters, pumps, etc.
− Generally, before an extended yacht lay-up period (including winter
storage), the seawater-cooled components of all engines should be
flushed with fresh water and the closed-system coolant levels should
be checked and filled to specification as indicated. If winterizing, the
seawater-cooled systems also should be properly protected with a
suitable, non-toxic antifreeze.
− Check the condition of the engines’ internal sacrifical anodes.
Replace if indicated.
− Clean engineroom and bilge. Ensure that contaminated bilge water is
not pumped into the marine environment. Use oil absorbent products
to trap oil and petroleum byproducts. Dispose them in an approved
manner.
− Spray all electrical, mechanical and hydraulic equipment and fittings
and engines with a corrosion-inhibiting formula suitable for use on
metals, electrical equipment and non-metal items such as rubber and
plastics.
− Perform pre-lay-up maintenance for transmissions (gearboxes) in
accordance with the recommendations found in the manufacturer’s
equipment service manual.
