USCG Exam PracticeTides and currents — predictions and corrections
Slack water is best described as which of the following?
- A. The period of maximum flood current just before the tide begins to ebb
- ✓ The brief period of zero current flow at the turn of the tideCorrect
- C. A sustained period of reduced current speed during neap tides
- D. The interval between spring tide and neap tide when current is weakest
Why B is correct
Bowditch Ch. 9 §903 defines slack water as the brief period of zero flow at the turn of the tide. It is not a sustained period nor is it associated specifically with neap tides.
