Island-class patrol vessel

The Island-class patrol vessel was first designed and built for the Scottish Fisheries Protection Agency. As a result of the Royal Navy's experiences in the Cod Wars with Iceland, FPV Jura (loaned to the Navy as HMS Jura) and FPV Westra were put in fishery protection patrols, the Navy built a further seven. These ships were designed and built by Hall Russell of Aberdeen, Scotland.

This article is about a Royal Navy patrol vessel class. For the U.S. Coast Guard patrol vessel class, see Island-class patrol boat.
