Hi Peter
We were on board all winter., you need to be with us to know how snug and comfortable we keep the whole boat. If I can't sit in a Tee shirt there is not enough wood on the wood burner in the salon, the central heating (oil fired) takes care of the rest of the accommodation space.
You are quite correct, empty boat = winterise fully.

> We left the central heating ticking over 24/7. The ice was over 30 cm thick, we tried to drill though it but the drill was not long enough.
The same winter another moorer (live aboard) froze his toilet and bathroom, by not letting heat circulate into it. First he knew about it was when he tried to flush the loo!
Another live aboard, relying on a pot belly stove in the salon, had his central heating circulating pump and pipework freeze that was located in the engine room. I spent a day thawing that lot out.


And all these difficulties with boats left with heating on. Even more important to properly winterise if the boat is left unattended and without power for 6 winter months. That was an exceptionally hard winter but no one knows if this winter won't be just as bad!

you forgot one thing.......
if you have a shower, make sure the hose to the top is empty !!
( Yes I forgot that one year..resulting in a busted shower, and no water until fixed)

so now we put the hose with the shower head on the floor, with the faucet open

Hi Peter
I hasten to add that neither of the damaged articles were on my boat. We left the central heating ticking over 24/7. The ice was over 30 cm thick, we tried to drill though it but the drill was not long enough.

> Seriously? Change your insurance company?

Not likely! They were exceptionally good with a winter related claim and their service is first class. No increase in premium (or even an admin charge) when I sold shares in my boat.

If you neglect to take all precautions when laying up for the winter and omit some essential element and the boat sinks, don't you think your insurance company may ask who did the winterising? If it was the owner who has no qualifications, don't you think they may be hesitant in paying for repairs resulting from the owner's neglect / ignorance / carelessness?

> I changed a water pump that had burst due to freezing that was around 0.9m below the water surface.
Also a water level gauge that had ruptured on another Stainless tank.
Both during the seriously cold winter around six years ago, when we had -18 - 20C at night for two weeks and "highs" in the day of around -12C.

Yes, I suffered damage to below-the-waterline equipment from the exceptionally cold weather then too. -23 degrees in central NL. It's crazy to assume that the water below cms of ice will protect the engine room equipment, although most winters are pretty benign.

Not quite the same, but we ran three little 300-400t coasters and the crew of the sister ship of one of ours left it in Harlingen for a couple of days over Christmas with the fore peak full of water ballast - much of which was below water level of course. It froze solid and opened the bow up like a ripe fruit. As a small consolation to the owner it did prove the value of a watertight collision bulkhead as the ship didn't actually sink

I winterise the fresh water system as follows :

Shut off water tanks which are below the water line and to freeze hell will have to freeze over first. Warmth from 1 m under vessel rises.
Switch off water pump.
I have 2 systems to drain. A whale gulper to suck out pipes from lowest point in system and a gravity drain valve - Waterstop - to drain one hot water tank into a sump tank.
Then open all taps, shower and basin mixers to let air in.
Whole system is empty after 30 mins.
The put food grade antifreeze in via the taps and mixers so the vulnerable bits - the mixer elements get coated with 100% antifreeze. Any excess drains down to the lowest pipes.

Central heating and engine have 30% antifreeze mix in permanently.

Hi Pete,
Thanks for the information.
I had looked at the knowledgeBase and found the article helpful but not specific to my systems (why would it be?). Therefore it was helpful to a point.
I appreciate you directing me to the RYA link and will study this.
Best regards,
Nige

Hi Paul,

This is excellent information that you have provided, particularly guidance relating to the engine and dosing antifreeze via the intake strainer.
With regard to my H & C water system, I intend to blow through with compressed air in order to remove water from within the system.
Thank you very much.
Kind regards,
Nige

Hi Peter,
Thanks for the guidance.
I have checked with my insurers and I can winterise the barge so long as I comply with a couple of basic requirements.

Best regards,
Nige

Hi Nigel

I composed this quick list for someone a few weeks ago. It was off the top of my head, and may not be relevant to your vessel. But is a good starting point.

Please use it as a "Pick and mix" , Hope it helps.
Paul Hayes

" Without knowing the actual systems on your boat, but I think I've seen and winterised enough boats to take a good shot, I can make a list:

Water system.
1)Turn of electric water heater, and mark "Do not turn on - Winterised"
2) Empty water tank, by running the outlets (taps - faucets).
3) Drain hot water calorifier (hot water tank).
4) Disconnect cold water "In" to calorifier.
5) Disconnect "Hot outlet" from calorifier.
6) Make bypass pipe from "cold in" pipe to "Hot out pipe"
7) Disconnect drinking water pump supply pipe
8) make up temporary flexible pipe to the supply pipe, approx 1.5 metres long.
9) Add food safe grade antifreeze to a bucket, insert temporary pipe,
10) turn on the pump, run antifreeze though all outlets, showers toilets, washing machine dish washer (start cycles on each).
11) continue to top up bucket with antifreeze.
12) when antifreeze is apparent at all outlets, isolate pump and leave outlets open.

13) Add automotive grade antifreeze to all drain outlets, toilets, showers, etc. and pump though grey water tank dry.
14) pump black tank dry.

Heating system - check if antifreeze has been added (hydrometer.)
If needed then antifreeze (Food safe or specific heating system antifreeze such as Sentinal X500 should be added.

1) Drain approximately 10 litres from system.
2) Make up adapter to a radiator port 1/2" BSP, and pump antifreeze into system using a "5L Garrden spray pump", or any other suitable pump,

Engine - Generator

1) Check engine primary closed system for antifreeze ( hydrometer)
2) If required drain off coolant, run engine to mix.
3) Add antifreeze.
4) Raw water secondary circuit - remove top of intake strainer
5) Close seacock
6) Add antifreeze to strainer, have plenty on hand, approx 20 litres.
7) Start engine
8) Add antifreeze to the strainer continuously
9) Watch exhaust and stop engine when antifreeze comes out.
10) Add antifreeze to strainer - open seacock - continue to pour antifreeze say 5 litres, close seacock so that it's full of antifreeze.

Generator and air conditioning as above.

So pretty straight forward really."

For starters, there is a compendium of members responses on the Forum to this question in the past, in the Knowledgebase article Internal - Winterising . Any new suggestions may be added to that.

RYA have recently published an article Winterising Top Tips

Good morning all,
I am being charged what I consider to be excessive fees by a third party for winterising my Tjalk.
Winterising is something that I now want to undertake myself but I need some guidance. I think that I know the answers to my questions but the implications of getting it wrong are scary.
Would it be possible for any members who currently carry out their own winterising to PM me so that I can ask some simple questions in relation to my domestic hot and cold water and main engine cooling systems.

Thanks in advance,

Nige
