Requirement to Have Sound-Producing Devices
In periods of reduced visibility or whenever a vessel operator needs to signal his or her intentions or position, a sound-producing device is essential. The navigation rules for meeting head-on, crossing, and overtaking situations are examples of when sound signals are required.
Use this chart to determine the sound-producing devices required for your vessel.
