The Current Screens. The Current screen displays the time of the maximum cur-
rent, its speed, its angle (direction) and the time of the slack water for the date
and station indicated on the screen. There may be more current information
than can be displayed on one screen. You can use the up and down arrows to
scroll through the available data.
You can also view a graph of the current for the 24 hour period of the day you
have selected. The upper portion of the graph represents the current of the rising
tide, the lower represents the current of the falling tide. The horizontal line
through the center at 00.00 represents the slack water. Each peak represents the
maximum current.
