Question 504Rules of the Road90% to pass

BOTH INTERNATIONAL & INLAND In restricted visibility, which signal shall a vessel fishing with nets sound at intervals of two minutes?

AI Explanation
The correct answer is B) One prolonged followed by two short blasts. This signal is required by the International Regulations for Preventing Collisions at Sea (COLREGS) Rule 26(d) for a vessel engaged in fishing with nets. In restricted visibility, this signal must be sounded at intervals of not more than 2 minutes to indicate the presence and location of the fishing vessel to other vessels in the area. The other options are incorrect because: A) Two prolonged blasts in succession is the signal for a vessel not under command, C) One prolonged blast is the signal for a vessel towing or pushing another vessel, and D) One prolonged followed by three short blasts is the signal for a vessel not under command.
