Back in 1998, Clive and Jane Green set off for a week's sailing trip to Spain. That week turned into the trip of a lifetime - and now, after 16 years of globetrotting, they're back home on Welsh soil.
The couple wanted to make sure they could get along living in a cramped 35ft sailboat before attempting an ocean crossing and so decided to take a shorter voyage to Spain. Once they arrived, there was no stopping them.
The pair rented out their home in Abergavenny to fund the early part of the trip before their pensions kicked in and set off to live their dream.
Over the next 16 years, the Greens visited 51 different countries, lived with tribes in the South Pacific and navigated through dangerous waters off the East African coast. And during that time, they say they didn't have a single row.
Clive, 62, and Jane, 60, spent almost £20,000 fitting out their Trident Challenger yacht - the Jane G - and clocked up an average speed of 4.5mph.
They lived on £130 a week, bartering with their belongings for supplies to keep them going - including swapping one of Jane's bras for a sack of fruit and vegetables on the island of Fiji.
The seasoned travellers are already planning their next adventure on a boat through the canals of Europe.
