Is it possible to change a cool box to a fridge/freezer application to run off 12V and mains electrical supply? Or is the solution a new installation to fit a fridge freezer.

Bash out the old box, extend and add plenty of insulation, get local glass fibre bloke to flowcoat inside, add evaporator & site compressor in an adjacent space.
If you have a suitable coolbox/locker, then it might be better than the major surgery involved in in fitting a full unit.
(With a decent fitted charger & shore power, I didn't bother with a seperate mains feed)
Now, if only I could make a *tiny* 12v freezer, just large enough to make a dozen ice cubes..."when the ship arrives in a wine country, there the master shall procure them wine to drink." Article XVII, Rules Of Oleron

This is an article written by a Westerly Konsort owner who retro-fitted a fridge unit to an existing coolbox.
I have a very similar installation on my Konsort Duo.

New evaporator plate in existing coolbox:-
Compressor and extra battery under cockpit floor.
The existing coolbox had 90mm of insulation round it as I found when drilling for the pipes but this is down to the double skin "unsinkable" construction. But it does mean that the fridge uses a manageble amount of battery power when at anchor. Note that running the pipes is a slow careful two-person job if they are not to be damaged. All the kit comes gassed-up with simple compression fittings for easy DIY connections. I got mine http://www.penguinfrigo.co.uk/shop/c...c-evaporators/.

I am toying with idea of doing this but wonder if it's worth the £400 or so. Did you get substantial benefit out of your upgrade? Your cool box looks exactly like mine, but I don't have a Sadler.

Like DJE we changed our cool box by fitting an Isotherm kit but they are all similar ideas on a theme and often share components. Brilliant bit of kit and is very quiet, runs 2 minutes in 15 or so depending on use. Minimal electrical use.
Our coolbox had 50mm of insulation, so I added several layers of that B&Q silver radiator insulation stuff, taped the edges and added a plug to the coolbox drain to minimise the movement of cold air. Condensation can be a problem after a couple of days use but a couple of cloth beer mats in the bottom of the fridge mops it up nicely.
