🔍 Key Concepts

• Charted depth vs. actual depth: Understand how to adjust the charted sounding for the actual tide height. • Draft of your vessel: Remember that depth under the keel is depth of water minus draft. • Negative tide height: Know what a negative tide (+ or -) does to the charted depth.

💭 Think About

• First, what does the number shown on the chart represent in terms of depth and reference level? • If the tide is -1 foot, do you add or subtract that from the charted depth to get actual water depth? • Once you know actual water depth, how do you use your vessel’s draft to find depth under the keel?

✅ Before You Answer

• Confirm the charted depth at the location between buoys 13 and 14 on the appropriate chart. • Verify the vessel’s draft used in this exam problem from the reference sheet or earlier in the exam. • Be sure you apply the tide correction with the correct sign (negative tide reduces depth, positive tide increases it).
