Because it never hurts to plan ahead

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.

Time of Slack or Max before desired time
Speed of max or slack (0.0)
Desired Time
Speed at desired time
Time of Slack or Max after desired time
Speed of Max or Slack (0.0)
