Giant Electric Canal Boat

Mark Evans meets Nigel and Tina Powell and their dog Stich, who are planning to live full time on a narrowboat. Stich needs a quiet engine. To keep him calm, the couple have commissioned a fully electric narrowboat. They've also requested a bespoke heart-shaped window at the bow of the boat. Can the boat maker deliver everything,within Nigel and Tina's £230,000 budget?
