What is the minimum frequency for sound signaling according to COLREGs for a vessel of 10 meters?

Under the COLREGs (International Regulations for Preventing Collisions at Sea), vessels of 10 meters or longer are required to sound signals for distress and to make their presence known, especially under conditions of limited visibility. The regulations specify a frequency for these sound signals to ensure that other vessels can hear and locate them in case of emergency.

For a vessel that is 10 meters in length, the stipulated minimum frequency for sound signaling is every two minutes. This regulation is designed to ensure a clear and manageable signaling system, allowing vessels to communicate their presence effectively without overwhelming the auditory environment with continuous signals. The timing ensures that other vessels have regular opportunities to detect the sound signal, thereby enhancing safety on the water.

The options that suggest a different frequency do not align with the specified guidelines in COLREGs for a vessel of this size, leading to the determination that signaling every two minutes is the legally established requirement in this scenario.
