INTERNATIONAL ONLY Which signal is sounded ONLY by a vessel in sight of another and NOT in or near an area of restricted visibility?
AI Explanation
The correct answer is A) One short blast on the whistle.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), the signal of one short blast on the whistle is sounded by a vessel to indicate "I am altering my course to starboard". This signal is only used by a vessel in sight of another vessel, and not in or near an area of restricted visibility.
The other options are incorrect because: B) One short, one prolonged, and one short blast is the "I am operating astern propulsion" signal; C) One prolonged blast is the fog signal; and D) Four short blasts is the danger signal, which is not the appropriate signal in this situation.
