- Q192 - Navigation Problems: Chart Plot
9. At 0405, you increase speed. At 0500, your position is LAT 37°06.0'N, LONG 75°41.1'W. What is the approximate depth of the water under the keel?
The depth under the keel is calculated by adding the charted depth and the interpolated tidal height at the vessel's position and time, then subtracting the vessel's draft, resulting in approximately 46 feet (13.9 meters).
