Question 1482Navigation General

The correct answer is D) All of the above. The U.S. Coast Guard regulations allow certain towing vessels to be exempt from the requirement to carry radar, including: 1) Vessels that have been exempted in writing by the Captain of the Port (option A). 2) Vessels used solely in a limited area, such as a barge fleeting area (option B). 3) Vessels used solely for pollution response or assistance towing (option C). These exemptions are outlined in the regulations, which recognize that in certain limited situations, the radar requirement may not be necessary or practical for the vessel's operations. Therefore, all the listed options are valid exemptions from the radar carriage requirement for towing vessels.
