🔍 Key Concepts

• tidal datum as the reference level used on nautical charts • difference between height of tide and depth of water • how charted depth is shown on a chart compared with the water level at a given moment

💭 Think About

• Ask yourself: is the question talking about a fixed value on the chart, or the water level at this particular moment? • Think about what mariners add or subtract from charted depth to find the actual water depth under the keel. • Which term describes a changing vertical distance measured from the tidal datum up to the sea surface at a specific time?

✅ Before You Answer

• Be clear on the definition of tidal datum (a reference level, not the sea surface). • Separate in your mind: (1) depth printed on the chart, (2) water level at the moment, and (3) total depth under the keel. • Verify which choice refers specifically to the vertical distance that can go up and down with the tide, measured from the datum.
