A credentialed Master of Towing Vessels may NOT serve as the person in charge of which towing vessel?

AI Explanation
The correct answer is D) 349 GRT towing vessel operating between Florida and Puerto Rico. A credentialed Master of Towing Vessels is not authorized to serve as the person in charge of a towing vessel operating in the "coastwise" trade, which includes voyages between Florida and Puerto Rico. This is because the Master of Towing Vessels credential is limited to "inland" and "near coastal" operations, and does not cover the "coastwise" trade. The other options (A, B, and C) involve towing vessels operating in "inland" or "near coastal" waters, which a Master of Towing Vessels would be qualified to operate.
