🔍 Key Concepts

• Tide Tables give the height of the tide above (or below) the chart datum, not the total water depth • Charted depth on the nautical chart is measured from the same chart datum used by the Tide Tables • To get actual depth of water, you must combine the charted depth and the tide height correctly

💭 Think About

• Ask yourself: Does the Tide Table value already include the charted depth, or is it a separate height that must be applied to it? • Think about a low-tide situation: If the Tide Tables show a negative value, what operation with the charted depth would make physical sense? • Consider what units are involved: If both the charted depth and tide height are in feet or meters, which mathematical operation keeps the units as a realistic water depth?

✅ Before You Answer

• Verify that Tide Tables give a height of tide, not total depth • Confirm that the chart datum used on the chart and in the tables is the same reference level • Make sure the final method you choose results in a realistic total water depth in the same units as the charted depth
