Colin & Shaun head east on the Leeds and Liverpool Canal towards the Rufford Branch and Tarleton Lock, where a trip across the Millennium Ribble Link to the Lancaster Canal awaits. The lads find out why narrowboats and fast-flowing tidal rivers aren't an ideal match. Danger awaits! Will their brand new home sink on the Ribble Link?

After crossing the Ribble Link, Colin and Shaun begin their new adventure on the Lancaster Canal.

Colin and Shaun continue their journey north on the Lancaster Canal calling at the city of Lancaster, Hest Bank, Carnforth, and reaching the end of the navigable canal at Tewitfield. The last few weeks catch up with Colin and he suffers an autistic meltdown leading to an insight into how mental health issues lead the couple to the canal. This episode contains discussion of mental health issues.

Back on the Leeds and Liverpool Canal, Colin and Shaun begin a new journey, this time heading east towards the Lancashire towns of Parbold and Appley Bridge. Onwards, they explore the canalside history of Wigan. The lads climb the formidable Wigan Flight of 21 locks and look back on their first few weeks living aboard narrowboat Silver Fox.
