So if you know that you'll be coming into an area of high current and you don't want to have to fight the current the
whole way in, what do you do? You ride in on a slack or flood. How do you know when those occur? Guess. No, solve like you
did for Speed at Any Time, but in reverse.
Step 1: Solve for the times of the nearest slack and max currents surrounding your desired date. You
should at least know what date you'll be coming in.
Step 2: If you know the maximum current you want, pick the times of slack and max current that would
provide you with the desired current nearest to the desired time.
Step 3: Build a table like the one at right to simplify your addition and subtraction.
Step 4: Divide your desired current by your max current to find your Speed Correction factor.
Step 5: Find the Time Between Slack and Max Current, and note your speed of max current.
Step 6: In the interpolation table in the back of the Tidal Current Tables, interpolate to find the
Time From Slack To Desired Time.
Step 7: Add or subtract this value to the time of Slack to find the nearest time at your desired speed.
To find how long the current will remain that speed, see Duration of Slack.
