Which tank barges require draft marks?
AI Explanation
The correct answer is D) All tank barges.
According to the regulations in 46 CFR 42.13-15, all tank barges, regardless of their gross tonnage, are required to have draft marks. This is because draft marks are essential for determining the vessel's draft and displacement, which is critical information for safely operating and loading tank barges.
The other options are incorrect because they either set an arbitrary gross tonnage threshold (options A and B) or specify a lower gross tonnage threshold (option C), which is not in line with the applicable regulations.
