Question 478Rules of the Road90% to pass
INTERNATIONAL ONLY A vessel sounds two short blasts. What does this indicate?
AI Explanation
The correct answer is C) The vessel is altering course to port.
The International Regulations for Preventing Collisions at Sea (COLREGS) state that a vessel altering course to port should sound two short blasts on the whistle. This indicates to other vessels in the area that the altering vessel is changing its course to the left (port) side.
The other answer choices are incorrect because they do not accurately reflect the meaning of the two short blasts signal. Sounding two short blasts does not indicate the vessel's intention to alter course (A, D) or that it will alter course (B), but rather that it is currently altering course to port.
