Caister Volunteer Lifeboat Service, or Caister Lifeboat, is based at Caister-on-Sea in Norfolk, and operates one of only three offshore lifeboats in the UK that are independent of the RNLI. A lifeboat at Caister was first documented in 1791, being used by the Caister Beach Company to salvage ships wrecked on the sand banks offshore from Caister. Between 1856 and 1969 lifeboats at Caister were operated by the RNLI.
