CURRENT DIAGRAMS 
Georges Bank Explanation  Hourly directions and velocities of tidal currents at 4 stations are shown by arrows. The length of the arrow from the centre of the circle represents the average velocity on a scale of 2.54 centimetres (1 in.) equals 2 knots. The figures at the arrow head are the hours after high water at Yarmouth, the daily predicted times of which are given in the Canadian Tide and Current Tables. The velocities plotted should be increased by 20% when the moon is full or new and decreased by 20% when the moon is in 1st or 3rd quarters. For effect of wind on tidal currents, see the Sailing Directions-Nova Scotia (Atlantic Coast) and Bay of Fundy.
