Question 1537 Deck Safety

The correct answer is A) coastwise service. Vessels certificated for coastwise service must carry a line-throwing appliance as per the requirements in 46 CFR 199.201. This regulation applies to vessels of 600 GT or more operating in coastwise service, which includes voyages along the coasts of the United States, its territories, and possessions. The other options are incorrect because vessels certificated for Great Lakes service or river service do not have the same requirement to carry a line-throwing appliance, as those operating areas do not necessitate this safety equipment.
