South African-born Linda, her husband Mark and Coco the cat share a one-bedroom floating home on Tagg's Island in Hampton, Surrey. It's an idyllic location, but their home is also their workplace and it's starting to feel a bit cramped. The couple want to stay put in their exclusive location, so Linda has hatched an ambitious plan to buy the boat next door and do it up all by herself. It's a huge challenge and it remains to be seen whether enthusiasm and passion will be enough to get the job done.

Retired customs officer Keith has been living and working in New Zealand for 25 years. Now, he wants to return to the UK for part of the year and go touring the waterways of the UK with his wife Pam. He's commissioning a brand-spanking-new semi-cruiser narrowboat complete with all the latest gadgets. However, Keith has never owned a boat before, let alone skippered or crewed a narrowboat, so he needs to learn very quickly.
