Renato said: 'There are so many jobs to learn - from how to use solar panels, navigation, map reading, how to dive.

'It's like being a new student. There was so much to learn.'

Although they don't keep track, the couple estimate that they have so far covered around 5,000 miles.

The longest landless stretch they have completed so far was the Atlantic crossing of 15 days from.

As well as having saved up before setting off, the couple fund their travels by offering travellers the opportunity to get a taste of sailing life and join them on a stretch.
