I thought I would expand a little on the tasks to prepare the ship for winter. Over the last years we do not see really low temperatures but if you do hit a hard freeze it’s too late to do the necessary!
Domestic water. Empty tank, fill pumps and loo with anti freeze mixture.
Engine change oil and filter, check antifreeze percentage in fresh water cooling circuit, run engine to temperature and induct antifreeze into and through raw water circuit.
Flags off, free off shrouds prior mast lift off, open lockers and ventilate under seat squabs, gas tank off, tools off, anti mould treatment for teak deck.
Instruments off.
Rub down and redo anti foul
Well done seems like you have most of it covered for the winter.
