What is it?

Seen this on a few boats over the weekend

The metal bit between the doors from floor to roof.

Its the front panel of an alde gas boiler used to heat water for a radiator circuit. Lots of them are installed in caravans and boats. Later versions have a balanced flue system. I have used several of these in the past and found them very reliable, space saving, and efficient. Some people are keen to say that they are inefficient and use lots of gas, a look at the temperature of the roof level exhaust should prove that this is not true and that they are in truth quite efficient.
