A team of search and rescue workers from the East Midlands is sailing around 1,999 miles of British coastline in a small inflatable boat.
The team, mainly from Derbyshire, began at Poole Harbour, Dorset, earlier and will visit eight lifeboat stations before finishing at Poole's RNLI college.
They aim to raise £20,000 for the RNLI and Watersafe UK Search & Rescue Team.
