Yes, normal electric underbench fridge, with chiller (freezer) compartment
What sort of cooker?
Gas 4 burner hob with oven and grill, some are built in, some free standing.
Are there electric sockets?
The boat has 240 electric with normal 3 pin sockets, there is a limit to what it can run, but fine for charging electrical kit, and a bit more. We supply the hair dryer. If you can’t live without straighteners it will run those.
