D. Decommissioning for Storage (Winterizing)
Winterizing consists of removing gear and equipment that may be damaged, removing liquids that
may freeze, thorough cleaning of the yacht, and protecting the yacht from the elements. Procedures
for winterizing are described below:
1. Drain fresh water system
a. Open faucets and run pump until water flow stops.
b. Disconnect hoses at pump and use air pressure to blow out water in low spots.
c. Remove drain plug on bottom fitting of water heater.
d. Pump hand pump until water flow stops.
e. Leave all faucet valves in open position.
NOTE : Non-toxic anti-freeze for fresh water systems is available from many marine supply
stores. This is recommended, since it will protect the system from any accumulations of water
that were missed in the draining operations. Disconnect hot water heater in and out hoses and
install a length of hose between the two ends. Disconnect hose on top of water tank that goes
to pump. Make up an extension hose and put end in non-toxic anti-freeze container. Pump
anti-freeze through hot and cold water systems.
2. Head and holding tanks
a. Winterize head by following the procedure given in the manufacturer's manual. Empty
holding tank and rinse with fresh water and pump out again.
3. Thru-hulls
a. For in-water storage, all thru-hull valves, except cockpit scupper valves, should be
closed. Put anti-freeze in cockpit scupper hoses so they don’t freeze.
b. For out-of-water storage, leave valves open.
4. Engine
Follow the procedures outlined in your engine operating manual. Generally, these will
include:
a. Engine coolant. Two acceptable methods of winterizing the engine cooling system are:
(1) Complete drainage which involves closing thru hulls, removing all drain plugs
