Royal National Lifeboat Institution [SEP] Introduction
The Royal National Lifeboat Institution (RNLI) is the largest charity that saves lives at sea around the coasts of the United Kingdom, the Republic of Ireland, the Channel Islands, and the Isle of Man, as well as on some inland waterways. There are numerous other lifeboat services operating in the same area. Founded in 1824 as the "National Institution for the Preservation of Life from Shipwreck", the RNLI was granted a Royal Charter in 1860. It is a charity in the UK and in the Republic of Ireland. Queen Elizabeth II is Patron. The RNLI is principally funded by legacies and donations, and most of the members of its lifeboat crews are unpaid volunteers.
