Tidal Stream Atlases include detailed tidal stream direction and strength information for key locations in North West Europe. This information, when used in conjunction with Tide Tables, enables accurate calculation of tidal stream rates for a particular port when planning a voyage.

Each volume of Tidal Stream Atlases includes:

    ​​​Pictorial representations of tidal stream directions for each hour before and after the reference port

    Information on the direction and rate of tidal streams, including the effect of neap and spring tides on tidal rates

    Neap and spring tidal rates in tenths of a knot to help bridge-crews calculate the tidal stream rate on any particular day
