Question 1620Navigation General

The correct answer is D) All of the above. Towing vessels of more than 39.4 feet in length must carry charts or maps that meet all three criteria: 1) with enough detail to make safe navigation possible, 2) of the current edition or currently corrected edition, and 3) of the area to be navigated. This requirement is outlined in the Code of Federal Regulations (CFR) for the U.S. Coast Guard. The other options are incorrect because they do not fully capture the comprehensive chart/map requirements for these larger towing vessels.
