Question 2646 Deck General

The correct answer is D) U.S. Vessels 26 feet or more in length. According to U.S. regulations, all U.S. vessels 26 feet or more in length are required to display the "Discharge of Oil Prohibited" placard. This requirement is specified in the Code of Federal Regulations (CFR) under 33 CFR 155.480, which states that the placard must be displayed on vessels of this size to inform the crew and passengers about the prohibition on discharging oil into U.S. navigable waters. The other options are incorrect because: A) Vessels less than 26 feet are not required to display the placard; B) Foreign vessels are subject to different regulations when not in U.S. waters; and C) The requirement applies to all U.S. vessels 26 feet or more, regardless of whether they are engaged in commercial or noncommercial service.
