The most comprehensive and authoritative tidal current tables availableThis will be the ninth year IM has produced the annual tide and tidal current tables, which were formerly only available from NOAA. This is an important navigation publication that provides the times and velocities of ebb and flood currents at thousands of locations, along with information on rotary currents and the Gulf Stream. Most commercial vessels in the U.S. are required by the Coast Guard to carry this information, and recreational saltwater boaters will find it the most comprehensive tidal current information available.
