At the end of our first season with Freebird, we've decided to leave her on the water over winter (pontoon berth, Largs, Scotland.) We used to do this with our previous boat - but she was rather more basic (no water system on board for a start!) so we're anxious to do things right.
Not connected to shore power; galvanic isolator fitted; no dehumidifiers or heaters.
These are our plans thus far:
Drain the calorifier (by opening taps in "hot" position)
Drain water tank
Leave taps in "on" position
Remove deck shower head
Empty holding tank
Diesel 3/4 full
Close all through hull fittings/seacocks - heads, sinks, engine in/out
Engine winterised (probably by DDZ!)
Batteries left fully charged and connected, all isolators turned off (which will presumably leave the automatic bilge pump ready to spring into action)
Doors but not cupboards left open
Windows/hatches secured
Check hoists and halliards against frapping
Lock up shop
Double check mooring warps
Things not yet determined:
Tender currently strapped to bathing platform - leave on?
Outboard - currently secured to pushpit rail - cover and leave on?
Sails: on or off?
Is there anything I've overlooked - or do you have any comments? Any help or advice, as ever, gratefully received.
