Richard Larn OBE


Richard has had a storied history in the Royal Navy, having served for 27 years in a variety of significant roles. After teaching himself to dive in 1947 in the River Thames, his passion for exploring shipwrecks took off, and since then Richard has dived all over the world and on hundreds of wreck sites.

Richard’s career highlights include discovering and investigating the wreck of HMS Association off the coast of the Isles of Scilly, and using his ingenuity to help raise the Mary Rose in 1982, a feat which earned him a personal letter of thanks from the then-Prince Charles.

Other notable moments include Richard being awarded an OBE for his work in cataloguing UK shipwrecks through the National Maritime Record, and discovering the wreck of the Admiral Gardner which yielded millions of copper coins.

Richard has written over 60 books on the subject of shipwrecks, including nine about the Isles of Scilly, and will be talking about his adventures, British naval history and a number of key Scilly shipwrecks.
