What is the primary role of Auxiliary facilities during a marine event?

The primary role of auxiliary facilities during a marine event is to act as Coast Guard units under Search and Rescue (SAR) policy. This means that during a marine event, these auxiliary facilities are vital for ensuring the safety and security of participants by providing essential support in case of emergencies or distress situations.

Auxiliary units are composed of trained volunteers who assist the Coast Guard in various operations, especially in scenarios where safety may be compromised. Their involvement includes search and rescue operations, which are critical during marine events where the risk of accidents or unforeseen circumstances may increase. By being on standby, these facilities enhance overall preparedness and response efficacy during such events.

The other options emphasize roles that, while possibly relevant in some contexts, do not encapsulate the main function of auxiliary facilities in relation to marine events, where safety is the foremost concern.
