“Thorough and authoritative.”--Sea Kayaker

“A definitive work of instant appeal to seamen of all levels of experience.”--The Navigation Foundation

Every sailor knows that instruments can fail. Things get wet, break, fall overboard. Whether you’re safe on your boat or drifting in a life raft, let David Burch show you how to find your way no matter what navigational equipment you have. Often relying on common materials like a small stick, a plastic bottle, even a pair of sunglasses, Burch explains how to make use of all available means--from the ancient skills of Polynesian navigators to the contrails of airliners overhead--to calculate speed, direction, latitude, and longitude and to perform all aspects of piloting and dead reckoning.

Become an Expert Small-Craft Radar Operator

Nothing beats radar for guiding your boat through the darkest night or the thickest fog. Radar enables you to plot a fix from just a single buoy or landmark, and it is the only navigation tool that tells you not just where you are, but who else or what else is out there with you. Today's smaller, affordable, efficient radars make more sense than ever for sailors and powerboaters.

Adopted by the American Sailing Association for their radar course and used by professional and recreational radar training schools around the world, this complete, in-depth manual shows you how to:

Choose the best radar model for your sailboat or powerboatInstall, adjust, and operate your systemInterpret the images on your radar screenPilot your boat and track the movements of vessels around youUse radar to track and avoid squalls, outmaneuver competitors in a yacht race, and other specialized tasksInterface your radar with a digital compass, GPS, or electronic chart

"This book will turn you into an expert on small-craft radar operations. It covers everything--radar choice, installation, use, and how to interface with your electronics. Very comprehensive!" -- Boat Books

"Stands out among other books on the subject . . . an excellent introduction to radar." -- Power Cruising

"Radar is an electronic tool, the operation of which takes much more interpretation than any other--too little knowledge can be just as dangerous as none. Radar for Mariners helps you understand how radar works, explains its limitations, and shows you how to get the full use of radar's functions. This book should show up on the radar screen of anyone with radar--or contemplating getting one. I can't wait to go to my boat and stop playing with my radar and start using it." -- Good Old Boat
