Your input and/or contribution is requested for the next release of the American Practical Navigator, Pub. 09, more commonly known as “Bowditch”. This publication, as you likely know, is the quintessential encyclopedia of navigation. Given that navigation has changed so much over the years, especially in the last decade, your participation in the development and writing of this important and historical book is crucial to both safe navigation as well as documenting the current state of the art of navigation. Please see the flyer below for more information.
