All the fishing boats of the UK have a prominent registration code displayed on their hull. This comprises one or two letters that identifies their home port and a number that is unique to the individual boat. The red, black and white boat in the foreground of this photograph originates from Littlehampton (LI) and the blue and white boat in the background is in its home port of Wemouth (WY).
