This rapid guide covers all of the key aspects of navigation. A high standard of illustration and the use of full colour makes this a very easy reference to use, even under extreme conditions. This is a guide which should be carried by weekend coastal sailors who often abandon formal navigation skills in very familiar waters, only to need them in an emergency. It is part of the Companion series of cockpit guides. Every page is laminated for water resistance and the spiral binding includes a hanging loop. This results in a very durable publication, although it will be regularly updated and most navigators will want to keep up with the latest information.
