The SB Hibernia was a 75-ton spritsail Thames barge built in Greenhithe, Kent in England in 1906, and which was wrecked on the North Sea coast at East Runton during the night of 9/10 November 1937. Her crew of three were rescued by the Cromer lifeboat. The sailing barge was a sister to the Cambria which has been restored to full sailing usage, by the Cambria Trust. Built alongside the Hibernia, and identical in all respects, the Cambria was the last spritsail barge to operate commercially in the United Kingdom. The lifeboat is now a permanent display at the RNLI museum at Cromer.
