Step 1: Find the times of the slack and max current that surround your desired time, (see Time of Slack/Max
Current for additional help)
Step 2: Build a Table like the one at right and fill in all of the info you already know
Step 3: Find the time difference between Slack and Max Current, the time difference between Slack and
Desired Time, and note the speed of nearest max current.
Step 4: In the Tidal Current Tables, you'll find a Table for interpolating to find Speed of Current
at Any Time near the back. Open up to this page and read the titles on the sides of the table.
Step 5: Using the values that you know, interpolate using the table and find your Speed Correction Factor.
Step 6: Multiply your Speed Correction Factor by the speed of nearest Max Current to find the current
at the Desired Time.
