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 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.

The Scottish Fisheries Protection Agency (SFPA) was an Executive Agency of the Scottish Government. On 1 April 2009, the Scottish Fisheries Protection Agency and Fisheries Research Services were merged with the Scottish Government Marine Directorate to form Marine Scotland, part of the core Scottish Government.
