We meet Carrie, a young woman from Doncaster who is moving from a 3-bedroomed house onto a narrowboat called Mabel, which she plans to redecorate from her permanent mooring in a marina. We join father and son team Paul and Chris in Derbyshire, as they run their floating pizzeria, The Waltzing Matilda, travelling the canals of the Peak district.

Emma continues her travels and tackles one of the 7 Wonders of the Waterways, The Anderton Boat Lift in Cheshire, but her boat is experiencing engine trouble and then springs a leak, which threatens to halt her epic solo adventure.

Emma and The Dawn Piper head towards the climax of their adventure - crossing the Pontcysyllte Aqueduct, but will her engine hold out long enough for her to realise her dream? Carrie takes Mabel on a cruise, and mum Della has a surprising announcement. And we meet married couple Paul and Anthony, experienced boaters who are upgrading to a new eco boat.

We meet a family of four on board Chugabug as they continuously cruise the network. Gary, Nikki, Noah and Lily love the freedom of being on the move as they home-school from their narrowboat. The family enjoy a nature walk, picnic, get busy in the kitchen and Noah chats to a class of children from the USA.

Paul and Anthony take a final cruise on their old boat Morning Star and have a helping hand with their big move to the new boat. Noah celebrates his birthday at Middleton Railway and the family take a hike to Malham Cove, and Carrie puts the finishing touches to Mabel. At the Horse-drawn boats in Llangollen there's a birthday party booked onto the boat.

We meet Vic, Jo and baby William who run Holly The Café Boat, as they cruise the Peak District looking for the perfect place to open for the season, Comedian Joel completes a gig in London and then sets off to unknown territory in the Midlands to try and complete his quest for a second gig, but first gets a visit from the "pump out boat" and we meet online yoga instructor May on the Oxford Canal.
