Spiral bound to lay flat or wrap its front cover all the way around for ease of use, The Mariner's Book of Days 2011 is a consumable, nautical desk diary and calendar. Each two-page spread lists a week on the right (the days include notes on the phases of the moon, famous nautical events in history, and plenty of blank space to write in) and extensive nautical history, facts, and trivia tidbits on the left. The Mariner's Book of Days 2011 is at once both a useful scheduling tool and an extraordinarily fascinating assembly of facts about life on the oceans and seas.
