The Narrow Boat Dover - a 1937 Town Class Woolwich Type F boat - is probably the most talked about canal carrying boat on the cut today. In the hit TV series 'Narrow Boat' she was seen being transformed from a rusting old hulk into the ultimate floating holiday home by owner Alan Herd. Now, in 'Narrow Boat Afloat', Alan Herd takes Dover on an epic and nostalgic journey down the length of the Grand Union Canal from Birmingham to London, where Dover was originally based. Starting out at the Gas Street Basin in Birmingham, the cameras follow Dover through glorious English countryside as she travels 126 miles and traverses 178 locks before reaching Brentford in London. Along the way, Alan meets various characters of the cut, stops to look at other historic narrow boats and uncovers traditional British industries that once relied on the canals. He explores the landmarks, locks, tunnels, warehouses and boatyards that make the Grand Union so memorable and - with the aid of rare archive film and photographs - reveals the history of the canal and those who plied a trade on it.
