Here is a useful guide for anybody who is uncertain about the ports identified by the letter L (LA, LH, LI, LL, LN, LO and LT) not to mention the letter P (PD, PE, PH, PL, PO, PT, PW, PZ) and all the other combinations used to identify UK fishing vessels, writes David Linkie.

Stewart Lenton’s new 16-page booklet booklet What is the Meaning of the Letters and Numbers on Fishing Boats? provides a valuable resource. In addition to presenting the port letter numbers (PLNs) in boat table and geographical format, it also provides an interesting insight into both the history of PLNs and their modern-day management.
