How long is the ferry? We leave ours turned off doing Plymouth to Santander and things don't defrost. Just put something in it for the first night like a frozen moussaka and it will still be partially frozen when you arrive. But leave the ice tray empty if you don't want a mini-flood. Of course run it at home for a good 24 hours before you leave to get it thoroughly cool.Two x 85 amp batteries and a 140w SP. If off EHU we would normally use gas but that is not an option on a ferry.
Why would you want to do that?
Fridges are most efficient on gas, they also have a 12v heating element. What you are suggesting would be the least efficient way of running it. Running on 240v from an inverter would use the same power as running on 12v plus the power the converter consumes.
With 2 say 100A/H leisure batteries and not wanting to discharge them more that 50% you would be looking at approx 6-10 hours depending on model of fridge.

Not these days, for about the last 10 years they have had thermostatic control on 12 volts.They are only thermostatic on 230v and gas

How long is the ferry?.
Absorption as it has a gas option, compressor would not have this option.Compressor fridge or absorption ?
Absorption fridge may draw up to 10amps per hour.....every hour.
They are only thermostatic on 230v and gas
A compressor fridge uses far less and only runs for 30 to 40 minutes total per hour so may be viable short term.
As already suggested......load the fridge with frozen goods and turn it off.
Even on a 12hr crossing it will still be frozen as the door will remain closed.

Twelve hours is nothing, as already suggested make sure the fridge is well filled and well chilled then add something frozen and just close the door. Do a trial at home if you want.Ships about 550 ft. Travel time is about 12 hours.
Just thought that using the inverter would ensure thermostatic control and as the fridge / freezer will already be cold would not use that much power.
Its an absorption fridge.
Brittany Ferries refuse to provide an EHU. Reasons given, not enough, need for a special very expensive adaptor.
If it can't be done we will work around. Thanks for comments.
