The Shannon-class lifeboat (previously FCB2 – Fast Carriage Boat 2) is the latest class of lifeboat currently being deployed to the RNLI fleet to serve the shores of the British Isles. While the Shannon class has mainly replaced the Mersey-class lifeboats, it has also replaced some Tyne-class and Trent-class lifeboats, and a Severn-class lifeboat.
