🔍 Key Concepts

• Using a tide table to find tidal height at a specific time • Adding/subtracting tide height to/from charted depth (soundings) to get actual water depth • Understanding interpolation between high and low water times/heights

💭 Think About

• What tidal stage is it at 0731 — closer to high water or low water, and is the tide rising or falling? • How would you estimate the tidal height at 0731 if the tide table only gives you high and low waters at set times? • Once you have the tidal height at 0731, how do you combine it with the charted depth at that position to get the approximate depth of water?

✅ Before You Answer

• Verify the charted depth (soundings) at the exact location referenced in the question • Confirm the times and heights of the relevant high and low waters from the tide table for that date • Check whether the question expects you to use simple proportion (rule of twelfths) or straight-line interpolation between tide events before choosing the closest answer
