Concrete Boat

Question
The Sir Henry is a concrete boat in a small pool a long way from the sea at Morton in the Marsh.
What possible use can it be?
Answer
It's at the Fire Service College; a former air field where you can be trained to fight every possible sort of fire.
The Sir Henry is regularly set on fire to practice extinguishing dock fires; so are the blocks of flats, oil refineries, a railway engine, overturned tanker and even the Boeing 737 at the college.
The picture was taken when I toured the site 30 years ago as a Bath City Councillor.
