🔍 Key Concepts

• Reversing current in tidal waters (change between flood and ebb) • Definition of slack water in current tables and tidal current diagrams • Difference between horizontal motion (current) and vertical motion (tide height)

💭 Think About

• Ask yourself: Is slack water about a change in current speed, water level height, or local wind effects? • Consider what happens to the horizontal flow of water right at the moment a current changes direction between flood and ebb. • Think about why mariners care about slack water when transiting inlets, narrow channels, or bridges.

✅ Before You Answer

• Verify how tidal current tables describe slack water around times of maximum flood and ebb. • Distinguish clearly between current speed (horizontal flow) and tidal range (vertical rise and fall). • Eliminate any options that still involve a noticeable ebb or flood current rather than a near standstill.
