Sooner or later everyone who ventures out on the water will encounter strong winds and confused seas, fog, thunderstorms, or heavy rain. This book acquaints boaters with the forces that shape weather, allowing them to predict what changes can be expected. Part I presents a logical explanation of climate and weather, concentrating on those aspects that affect the mariner the most–wind speed and direction, low visibility, thunderstorms, gales, and hurricanes. The second part, which can be read independently, deals with the effects of climate and weather on the boater without delving into the whys and wherefores–a practical approach for those who want only the needed facts.
