In this episode of The Water Road we investigate the world of electric propulsion boats, with a visit to the Electrika boat show. We hear how the show came about, learn about the different types of hybrid systems, drill down into the green credentials, and discuss some of the challenges for the future. Guests include Rob Howdle and Caroline Badger from the boat builders, Ortomarine; Ricky Lee from Finesse Boats; and Matthew Symonds from the Canal and River Trust. Plus we hear from the owners of electric boats about life on board, including the crew of Tethys, stars of Channel 4's Narrow Escapes.

In this episode of The Water Road we reach Foxton Locks, where we have quite a wait to get down Britain's longest flight of staircase locks. A volunteer lock keeper tells us why it's so important to operate the paddles in the right order, and gongoozlers tell us why they decided to visit the site. Plus we hear about the history of the inclined plane boat lift, which replaced the locks for a while early last century -- and why it proved a failure.

In this special edition of The Water Road, we talk to Richard Parry, who's stepping down this summer as Chief Executive of the Canal and River Trust. He answers questions about the performance of the charity, and warns that funding cuts means there's potential jeopardy for the canals in the future.
