The XP-class lifeboat is mainly used as a small tender carried onboard RNLI all-weather lifeboats, and is based on the commercially available Avon Rover 280.[3]
It carries a crew of one or two, and is normally found carried on board the Trent-class lifeboat.[4][2] It is used primarily for assisting in cliff incidents where the casualty is near the water, and where rocks prevent the all-weather lifeboat from getting near the base of the cliff.[citation needed]
Other small boats operated by the RNLI include the Arancia-class beach rescue boats, the X-class and the Y-class lifeboats.[4]
