Jon and Barbara Tucker were literally the boy and girl next door as they grew up in Christchurch in the 60s.
They were both from sailing families, and so it seemed natural to them to build a boat that would be their home.
And so they did - 45 ft wooden ketch called New Zealand Maid. Jon and Barbara married at 19 and 18 respectively and the first of their five sons was born two years later.
The Tucker family spent the best part of next three decades living aboard, criss-crossing the Pacific - the boys learning by correspondence while they were school age.
The Tucker boys are all grown up now and all seafarers, with children (and boats) of their own.
Jon's just published a book about the family's life at sea, called Well Intentioned Advice: A life-voyage afloat. He and Barbara join Kathryn Ryan in the studio.
