Question 349General Subjects - 1st Asst/Chief

The correct answer is C) 25 nautical miles. According to MARPOL Annex V regulations and 33 CFR Subchapter O, the prohibition of the discharge of dunnage, lining, and packing materials that float applies to vessels operating within 25 nautical miles of the nearest land. This is because MARPOL Annex V designates a 25-nautical-mile zone from the nearest land where the discharge of these materials is prohibited, in order to protect the marine environment. The other answer choices are incorrect because 3 nautical miles is the territorial sea limit, 12 nautical miles is the contiguous zone limit, and 200 nautical miles is the exclusive economic zone limit, none of which are the correct distance for the MARPOL Annex V and 33 CFR Subchapter O regulations on the discharge of floating dunnage, lining, and packing materials.
