Apparently there is a new print of this book since 2009.

Anyhow, this is a reference work on whitewater safety. This book includes all (nearly all) basic knowledge you need to have concerning whitewater safety.

Not only rescue techniques are covered, but also river features with their potential risks are listed. Theoretical background on given techniques is also included. After reading this book you'll have an idea of which knife or throwbag to take, and you'll understand why an undercut can be dangerous before ending up in one.

This book is a must have reference. Even if you do not read it from cover to cover, you should have it as a reference and look through it from time to time.
