The RNLI is the charity that saves lives at sea, providing a lifeboat service, lifeguards and safety education. The charity's founder, Sir William Hillary, vowed that 'with courage, nothing is impossible.' His vision of forming a rescue service funded by voluntary donations became a reality in 1824 and, almost 200 years on, the charity has saved more than 142,500 lives. Everyone who gives their time or support to the RNLI is a lifesaver.
