USCG Boat Crew Practice Exam

A tug towing astern is indicated by a specific light configuration which helps ensure other vessels can recognize the tug’s activity and respond appropriately. The proper configuration for a tug that is towing astern consists of a yellow light above a white light. This combination - yellow over white - communicates to other boats that a towing operation is taking place. The yellow light serves to signify that the vessel is engaged in towing, while the white light conveys the additional requirement for other vessels to give way according to navigational rules. Understanding this configuration is crucial for safe navigation on waterways, particularly in preventing collisions between vessels operating in close proximity. Identifying the correct light signals helps crews interpret the actions and capabilities of other vessels, promoting overall maritime safety.
