Question 485Navigation General

The correct answer is C) object may cover and uncover with the tide. When slanted letters are used to spell the name of a charted object, it indicates that the position or existence of the object is approximate or doubtful, and the object may cover and uncover with the tide. This is a standard convention used in nautical charts to convey information about the reliability and tidal behavior of the charted feature. The other answer choices are incorrect because: A) the use of slanted letters does not necessarily mean the object is always visible; B) the position is approximate or doubtful, not the position itself; and D) the slanted letters do not indicate the object is only a hazard to vessels drawing in excess of 20 feet.
