This was our onboard FRC, and was capable of 30 knots.
This primary use for this boat is in Man overboard situations. Whereas in the past you would have to make ready a Lifeboat, the FRC is the preferred method today.
Manned with a crew of 3, normally in BP it was the 2/O, 3/E and an AB.
It's designed for rapid deployment, thus the single davit, much preferable to a lifeboat, especially the enclosed type we had.
The 'bag' at the aft end is for self righting, should the boat go over.
