  1. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water.

  2. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 1: Dobbs Ferry is not a reference station so we need to look at the index for Table 2 to find the reference number.

  3. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 1: Dobbs Ferry is not a reference station so we need to look at the index for Table 2 to find the reference number. The index gives Dobbs Ferry a reference number of 3671

  4. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 1: Finding 3671 in Table 2 shows Dobbs Ferry as the name. Moving over to the differences column and then up shows the reference station to use is “The Narrows”

  5. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 2: We also see from the table that the time difference is ABOUT + 2hr 30m.

  6. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 3: From Table 1 we see that to be around 1000 we must use the second line of data.

  7. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 3: From Table 1 we see that to be around 1000 we must use the second line of data. A slack water will occur at 0757.

  8. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 3: From Table 1 we see that to be around 1000 we must use the second line of data. A slack water will occur at 0757. A maximum flood will occur at 1023.

  9. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 4: From table 2 we find a correction for slack water of 2 h 30 m

  10. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 4: From table 2 we find a correction for slack water of 2 h 30 m and for max flood 2 h 33 m.

  11. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 5: Correcting the times for slack, 0757 + 2h 30m = 1027. For flood we find 1023 + 2 h 33 m = 1256.

  12. What best describes the condition of the tidal current at Dobbs Ferry, at 1000 on February 20, 1995? A. It is slack water. B. The current has reached maximum flood velocity. C. The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 5: Correcting the times for slack, 0757 + 2h 30m = 1027. For flood we find 1023 + 2 h 33 m = 1256. Step 6: The answer therefore is D. Slack water will not occur until 1027 so the current is approaching slack.

The current has reached maximum ebb velocity. D. The current is approaching slack water. Step 1: Dobbs Ferry is not a reference station so we need to look at Table 2 to find the reference station to use is “The Narrows” Step 2: We also see from the table that the time difference is ABOUT 2h 30m.

Step 5: Correcting the times we find for slack, 0757 + 2h 30m = 1027. For flood we find 1023 + 2 h 33 m = 1256. Step 6: The answer therefore is D. Slack water will not occur until 1027 so the current is approaching slack.
