BOTH INTERNATIONAL & INLAND A vessel is "in sight" of another vessel when she __________.

A can be observed visually from the other vessel
B can be observed by radar
C is sounding a fog signal which can be heard on the other vessel
D has determined that risk of collision exists
AI Explanation

The correct answer is A) a vessel is "in sight" of another vessel when she can be observed visually from the other vessel. The definition of a vessel being "in sight" of another vessel is based on visual observation, not on radar detection, fog signal detection, or determination of risk of collision. The International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules clearly state that a vessel is considered to be "in sight" of another when it can be observed visually from the other vessel. The other options are incorrect because they do not accurately reflect the regulatory definition of a vessel being "in sight" of another vessel.
