Each year hundreds of boaters (sailors and power cruisers) travel on this sheltered water trail along the Atlantic east coast. Navigating the Intracoastal Waterway from Virginia to Florida, or vice versa, is certainly possible with only a chartplotter, but prudent mariners will invest in this printed backup chartbook to ensure they always know how to find their way along the thousand-mile route. This book is handy, up-to-date, and full of ALL the information needed to pass safely under bridges and anchor safely for the night.
