This will be my first winter with the boat on the hard and am looking for the best winterizing checklist. Thanks.

Depends where you are and how much you want to do but on the south coast of the UK I generally stop sailing in October and start again in March / April. With that in mind I accept I won’t use the boat over the winter and I….

Flush out holding tank with fresh water and put some disinfectant in (including the toilet)

Drain the water tanks after treating with sterilising fluid then I remove the inspection hatches and dry them out

Change engine oil and filter, flush the cooling circuit with fresh water and then antifreeze

Remove everything from the boat, including the sails and covers 

Spray “patio magic” on the cockpit seats and ropes to stop green algae 

Cover the cockpit table with a tarpaulin and remove the wheels (I do this mainly to avoid theft)

Charge batteries (but I have solar which keeps them topped up)

I’m not in a marina so I have to use dehumidifier crystals in lieu of a an electric dehumidifier

Fresh water:
1: Run water tanks empty (as much as you can)
2: If you have a city water connection, then you can get a hose to air hose fitting and use a small compressor to blow out the water in the hoses.  Make sure you open every tap one by one, including the cockpit shower, both hot & cold.  That should also get the water out of the hot water heater.
3. I then disconnect the output hose from the freshwater pump to ensure that is drained as well.

Toilet:
1. Get pumped out
2. Open gravity drain
3. Use the fresh water you're emptying from the tanks to rinse and flush many many times
4. leave dry

AC system (if you have it):
1. My AC drains underwater, so I waited until I was out of the water to open all the seacocks
2. Remove drain plug from pump and release water
3. Remove raw water lines from pump and use air compressor to push out water

Shower pump:
1. Run dry after haul out

All other sink drains:
1. Open seacocks and ensure water drains out after haul out

Engine:
A. I like to change the oil before the winter, so do that first.  There is plenty of debate on when is best, but I'd rather have fresh oil sitting in the engine vs old oil with possible moisture in it.
B. Fill your diesel tank
C. Winterize the raw water system:
1. Get 3 gallons of good non-toxic anti-freeze that is suitable for engines
2. Get 5 gallon bucket
3. Get a friend who is competent
4. Close seacock at saildrive and pull raw water hose from saildrive seacock and put the end in the bucket of antifreeze
5. Have competent friend start the engine and watch for antifreeze coming from exhaust
6. Shut off engine, re-attach hose but leave seacock closed.  Put a piece of tape on the engine controls that says the engine has been winterized.

Alternately depending on your engine, some say that the impeller is the lowest point on the engine, so if you pull the impeller cover and let the raw water drain out, you should be OK.  I've never liked that idea.  I leave the impeller in place and replace after the winter.

If you're in the northeast like me, then I also get 4 or 5 of those bucket style damp-rid containers and put them in every cabin.  I also remove all soft items (blankets, sheets, pillows, etc).  Some folks like to stand the cushions on edge but I've not really bothered because the damp-rid does a pretty good job of collecting excess moisture.

Batteries:
1. Depending on what your situation is, what power you might have available, and what kind of batteries you have, you probably need to arrange for some type of float charging / recharging.
2. I have two 110w flexible solar panels that I remove from my bimini and attach to my winter cover with strong magnets.  They go into a MPPT controller that then feeds the charge divider that keeps the house battery and starter battery topped up.  My thruster batteries are charged from the house batteries with a Dc-Dc charger, so i keep that "on" as well.  If you can't do that, then you need to periodically plug in a charger over the winter, or worst case (and heaviest) you would pull the batteries and keep them on a tender over the winter.

Other stuff
1. I remove all sails, fold them and put them in bags.  Clean / repair as needed
2. Secure all rigging so it's not chafing all winter
3. Clean refrigerator and prop open

That's all i can think of now...
i'm sure others will add more!

A very good list from Simon and Matt. In addition I would also add that when we left the lines in running under the coachroof panel back to the winches they went mouldy so now pull them through to mast and leave mousing lines in place. Then coil them up hanging under gooseneck with thick plastic bag covering all taped up. May be a wet UK problem!!

I use a lot of cable ties to tidy up the standing rigging and lazy jacks and keep all the ropework off the decks as it tends to go green. I also cable tie all the battens and to the stanchion wires for safe keeping.
Patio magic gets the thumbs up from me also.

Simon makes a great suggestion, to pull the hose off the saildrive seacock, to run fresh water or antifreeze through the engine. My question is whether anyone has found a good hardware setup, a permanent T-joint, where normally the raw water would flow through, but as needed, a garden house could be connected for flushing. West Marine and others carry a plastic fitting made by Perko for $115. However, its reviews are mostly terrible as users report the device splitting apart (not good!). On prior boats with Volvo Penta engines, the raw water seacock had a solidly built brass filter housing, onto which we could mount a high quality brass fitting to enable quick connect hose for flushing. On the Yanmar, the filter housing is plastic and the hoses are 1" rubber/plastic. Any suggestions?

A quick query on Matt’s point on spraying with ‘patio magic’. Anyone had any issues with this on flexiteak, windows, solar panels or silicone sealant? I’m always a little nervous with potential unexpected chemical reactions…

I've used it each winter on my cockpit flexi teak (cockpit sole and seats) with no issues. To be completely accurate I'm using "Doff Patio, Path & Decking cleaner" rather than the actual "Patio Magic" brand but I believe they are all similar in preventing green algae growth.

Dubs 2021, Rather than introducing a T piece when winterizing our engine we flush antifreeze via the water strainer. The last time the engine is used we close the seacock, open the water strainer then start the engine then pour in antifreeze via the water strainer until flushed out the exhaust. When lifted and on hard we open the engine seacock which drains any water in left in inlet pipe and flush with antifreeze via water strainer. 
This video by Tom Cuncliffe on winterizing is excellent and uses same process.

Hope it helps,
Jon
