World Class Catamarans

WINTERIZATION
Routine maintenance checks should be performed prior to each trip in accordance with
Chapter 1, but a broader analysis should be done before winterizing your catamaran and prior
to the first trip of the season. If your local climate does not require winter storage, complete the
following steps at least annually to ensure the safe operation of your boat.
1. Do not leave loose items or personal affects onboard during storage. Remove all trash
and debris prior to cleaning the boat.
2. Before storage clean the boat thoroughly, including exterior surfaces, fishboxes,
livewells, and thru hull fittings. If possible leave lids open slightly to allow fresh air
exchange. Remove the garboard drains and store the boat with the bow up to allow
drainage.
3. Inspect all electrical connections and the operation of pumps or other electrical
devices. Perform repairs if necessary. Coat electrical panels with an anti-corrosive
spray, available from your dealer.
4. Inspect the batteries and charge fully to prevent damage during storage. Disconnect
the cables and apply a coat of grease to the terminals to prohibit corrosion.
5. Inspect all plumbing components and connections to prevent leaks. Replace any dam-
aged hoses. Drain all lines and devices to prevent damage from freezing. Lubricate
valves to maintain proper operation. Use the manufacturers recommendations for por-
table and marine heads.
6. Inspect fuel system components and replace fuel/water separators. You can keep the
system fuel but do not overfill, and use a fuel additive to prevent condensation.
7. Lubricate hinges and coat all metal surfaces with Boeshield T-9™ or other metal pro-
tector. Tighten down hardware if necessary.
8. Inspect caulking around hardware, windows, hatches, etc. to prevent water damage.
Normal use will break down sealants and can lead to costly repairs if not maintained.
9. Remove or cover all electrical devices to prevent damage from UV rays. The rays will
cloud electrical displays and make them hard to read.
10. Remove cushions and store indoors to prevent damage.
11. Winterize the engines and controls per manufacturers recommendations and inspect
all connections, filters, and parts thoroughly. Replace parts as needed.
