these compartments out then use a sponge to remove all 
remaining water. 
Procedures  for  draining  and  winterizing  the  fresh  water 
system  are  in  this  section  under  the  “Preparing  for 
Storage” heading.
14.6.2  Preparing for Storage
*  Clean, scrub, and sponge the hull and deck as soon as 
the boat is pulled from the water and is still in the sling.  
Cleaning marine growth from the hull is easier when it is 
still wet. 
*   Clean  the  inside of  all  hull  openings,  through hull  fit-
tings, and screens.  Inspect the hull and underwater gear 
for  signs  of  wear,  deterioration,  or  damage.    Note  any 
damage to the propulsion  equipment, helm area,  cabin, 
etc.  Make repairs, if at all possible, before covering your 
boat.
*  Fill the fuel tanks with treated fuel to prevent conden-
sation.  If you use a stabilizer or conditioner, be sure to 
follow the instructions on the container.
Important:  Do not overfill fuel tanks so fuel flows from the vent.  
Allow room in the tanks for fuel to expand.
** Prepare the Engines for Storage:
*    In  areas  where  temperatures  fall  below  freezing,  the 
bilge  area  under  the  engines  must  be pumped  out  and 
sponged  completely  dry.    Check  for  areas  that  do  not 
drain to the pumps.  Drain mufflers.
Note:  Refer to the engine owner’s manual for winterization and 
storage procedures.
** Prepare the Batteries for Storage:
*  Be sure main battery breakers are off.
*   Remove  batteries  from  boat  and  store in area where 
temperatures remain above freezing.
*  Place batteries on a wooden pallet or bench.
*  Keep batteries charged.  Check electrolyte levels regu-
larly.  Add electrolyte if needed.
**  Prepare Holding Tank
*  Empty and rinse holding tank until tank is clean.
*  Close head intake seacock and remove hose.
*    Pour  the  nontoxic  antifreeze  into  the  head  and  keep 
flushing the head until the antifreeze reaches the holding 
tank.
*  If your  boat  has  a  macerator  discharge  and  the  boat 
is removed from the water, run the macerator pump long 
enough  for  antifreeze  to  run  through  the pump  and  the 
lines. 
*  Remove drain plug from seacock while valve is closed.  
Allow line to drain.  Replace drain plug.
**  Prepare the Fresh Water System:
*  Remove the fresh water supply by opening the hot and 
cold faucets in the galley for 10 minute intervals.  Repeat 
until the fresh water tank is empty.
*  Open all faucets:  galley, shower, cockpit shower, etc. 
*    Drain  the  water  heater.    Disconnect  lines  from  the 
engine  heat  exchanger  (if  equipped).    Drain  exchanger 
and lines.
*    Remove  hot  and  cold  water  lines  and  hook  them 
together. 
*  Remove inlet hose from tank and insert it into a con-
tainer  of  nontoxic  antifreeze.    Turn  pump  on.    Starting 
at faucet furthest from pump, open all faucets until anti-
freeze flows out.
*  Turn off pump and reconnect hose to water heater and 
pump.
*  Remove seacock drain plugs to prevent damage from 
freezing. Close all seacocks.
**  Prepare Interior of Boat for Storage:
*  To keep mildew from forming, remove all items that will 
hold moisture ( PFD’s, towels, blankets, clothing, canvas, 
etc.).
*  Make sure all garbage is removed.
*  Scrub the inside of the boat.  Clean cabinets, drawers, 
and  cupboards.   Allow  cabin  area  to  dry  and  air  for  at 
least one day if possible.
*  Stand or prop up mattresses and cushions remaining
