USCG Exam PracticeApplying tide corrections to charted depth
A chart shows a sounding of 10 feet. The tide tables indicate the current height of tide is +3 feet above MLLW. What is the actual depth of water at that location?
- A. 7 feet
- B. 10 feet
- ✓ 13 feetCorrect
- D. 3 feet
Why C is correct
Charted soundings are referenced to MLLW (Bowditch Ch. 4 §403). When the tide is above MLLW, actual depth equals the charted depth plus the height of tide. 10 ft + 3 ft = 13 ft of actual water depth.
