My boat is always on the hard
unless I take it out. For that long of period here's a list of what I would do.
Flush out the motor
with fresh water
threw just before you shut it down. Then drain the coolings systems including the wetlift.
Flush out the toilet and holding tank
with fresh water and bleach, then drain them both.
Put a tarp over the foredeck if you have hatches up there. Hold them to the boat with bungee's tight. It will be shot after one year (in the PNW). Make sure
it can not balloon out in the wind
. Protect anything from rubbing the hull
, especially metal.
Cover the cockpit
area too. Cover the pedestal
if you have one. Cover the winches too if exposed to the weather
. If you have a closed cockpit
and it's not covered the drains may get plugged with trash/leaves, fill up and go into the cabin
Pull down all your sails
, rinse with fresh water and let dry. And the covers too, store them in a dry, ventilated storage
off the floor.
Pull you halyards away from the mast
or anything else so they don't slap in the wind
. More bungee's, they'll all be rotten when you get back. Buy new!
Depending on the yard security
you may want to pull your prop.
Fill your fuel tank
full and add a stabilizer (diesel).
Drain your water tank and lines and leave inspection
covers off to ventilate.
If you have power it would be good to set up a timer to run a hi-speed fan to run during the hottest/humid time of the day to avoid mold
Dry out the bilges. If you have a keel
you'll want to put lots of tape over the halyards where they come out of the mast.
The outside finish may try to oxidize on the West side especially reds or light blues. If it's white it'll just get chocky. Covering is the only prevention.
Make sure the stands are very secure for hurricane
force winds. And your neighbors too! Here we worry about earthquakes.
That's all I can think of for now......................._/)
