Y-class_lifeboat
The Y-class lifeboat is a class of small inflatable rescue boat operated by the Royal National Lifeboat Institution of the United Kingdom and Ireland.
The Y-class is mainly used as a small tender carried on board the larger RNLI all-weather lifeboats that serve the shores of the UK, and is normally found on the Severn-class[2] and Tamar-class lifeboats,[3] the Arun-class having been retired.[1] They are also used as part of the RNLI's flood rescue team.
When in use, it carries up to a crew of two and is primarily used in cliff incidents where the casualty is near the shore and the all-weather lifeboat cannot safely get to the base of the cliffs due to rocks.[citation needed]
Other small boats operated by the RNLI include the Arancia-class beach rescue boats, the X-class and the XP-class lifeboats.[4]
