Nailbourne river, that flows and dries as the chalk hills fill and empty. I've sailed the Atlantic, learnt (and mostly forgotten) the sailing light codes and bathed in a natural hot spring in Greenland while watching icebergs glide by.
But I still learnt masses and masses from this brilliant book.
For anyone who has any connection with water - and that definitely includes all sailors and kayakers - this is a must-have book.
Learn how to navigate like a Polynesian in a pond, use the reflection of Jupiter to spot bats, discover the best beaches on the Scilly Isles, where to look for gold in a beach and much, much more - this book is packed with fascinating information.
Worth having on a boat for those "I wonder what?" moments or taken on a walk along the coastline to understand the topography of a beach, the differences between ripples, waves and swell, how to read sand ripples and avoid those deadly rip currents.
Sure to be a classic - strongly recommended.
Two other reviews here and here.
Full disclosure: Tristan is a good friend of mine and this book mentions events that happened while we were sailing together plus I got a review copy.
