Having decided to buy a narrowboat to live on in London, Alastair realised that he didn't actually know anything about living on a boat. But how hard could it be? He discovered that unlike houses, boats can sink. He also found they're a lot easier to move than a house when you've been mugged and decide you don't want to live in that neighbourhood anymore.

In this book, Alastair travels all the way across London, from Brentford to Limehouse and discovers places he'd never heard of, a love of gardening and the joy of watching the sun setting over the canal. Nobody said that living on a boat in London was easy, but it turns out that there are plenty of wonderful pubs next to the canals, where you can sit with a pint and decide where you'd like to move to next.
