Question 2534 Deck General

The correct answer is D) U.S. Coast Guard. The U.S. Coast Guard is responsible for administering the load line regulations in the United States. Load lines are markings on a ship's hull that indicate the maximum draft to which the vessel can be safely submerged. These regulations are part of the Coast Guard's broader responsibilities for maritime safety and vessel inspections. The other options are incorrect because the National Cargo Bureau, Lloyd's Register of Shipping, and the Maritime Administration do not have direct authority over the load line regulations in the U.S. These organizations may play supporting roles, but the primary regulatory authority lies with the U.S. Coast Guard.
