Welty answers questions about sailing for those who navigate sailboats, connecting the questions to basic scientific principles and explanations based on his knowledge of physics and math. In a question and answer format, he discusses concepts such as floating, navigation and piloting, force, torque, engines, waves, light and optical phenomena, and conservation. B&w photos and illustrations are incorporated throughout. Welty is a retired teacher of physics and a full-time cruiser on his sailboat. (Annotation ©2008 Book News Inc. Portland, OR)
