World-famous yacht Gipsy Moth IV is returning from a second round-the-world voyage, 40 years after its first circumnavigation.
The yacht has helped introduce disadvantaged youngsters to sailing
The mahogany vessel has spent two years recreating Sir Francis Chichester's history-making 1967 trip.
This time the yacht was crewed by teams of disadvantaged children on its repeat 30,000-mile (48,300km) odyssey.
Thousands of people are expected to welcome the vessel back to Plymouth, to where Sir Francis also returned.
Gipsy Moth IV set off on its second lengthy voyage in September 2005 after undergoing a £300,000 refit.
The 53ft (16m) yacht had been held in dry dock in Greenwich, London, for decades until the UK Sailing Academy, based on the Isle of Wight, bought the boat for £1 and a gin and tonic.

The refurbished ketch set out from Plymouth, Devon, crewed by teams of three 16 to 23-year-olds from disadvantaged backgrounds.
The journey introduced almost 90 young people to the challenges of sailing and in May last year the yacht had to be rescued after becoming grounded on a South Pacific reef.
After returning to Plymouth, Gipsy Moth IV will travel to the Isle of Wight port of Cowes to join the UK Sailing Academy's fleet of yachts used to take young people on sailing trips.
Sir Francis Chichester returned to Plymouth Sound in 1967, nine months and one day after setting sail round the world.
The journey was the first true solo circumnavigation via the three Capes of Hope, Leeuwin and Horn, making only one stop.
Thousands of small boats were waiting to accompany the 65-year-old yachtsman back to port, where he was given a 10-gun salute from the Royal Artillery.
The adventurer was later knighted by the Queen with Sir Francis Drake's sword.
Gipsy Moth IV will return to Plymouth on Monday and Cowes on Sunday 3 June.
