Requirements 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.

These requirements apply to vessels operating on Georgia state waters.

• Vessels less than 26 feet long, including PWC, are not required to carry a sound-producing device, but it is highly recommended.
• Vessels 26 feet long or longer are required to have a whistle, horn, or other sound signal.

These requirements apply to vessels operating on federally controlled waters.

• Vessels less than 39.4 feet (12 meters) in length, which includes PWC, must have some way of making an efficient sound signal. Examples are a handheld air horn, an athletic whistle, an installed horn, etc. A human voice is not acceptable.
• Vessels that are 39.4 feet (12 meters) or more in length must have a sound-producing device that can produce an efficient sound signal. The sound signal should be audible for one-half mile and should last for 4 to 6 seconds.
