Question 1423Navigation General

The correct answer is A) when a new Master assumes command. The reasoning for this is that according to Coast Guard regulations, the owner or Master of a towing vessel is responsible for ensuring that all tests and inspections of gear are conducted and logged when a new Master assumes command. This is to ensure that the incoming Master is aware of the towing vessel's equipment status and maintenance history, and can properly manage the safe operation of the vessel going forward. The other options (B, C, and D) do not align with the specific Coast Guard regulation regarding this requirement.
