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 West Virginia state waters.

• Vessels less than 26 feet in length, excluding PWC, must carry a mouth whistle or a power-operated horn or whistle capable of producing a blast that is audible for at least one-half mile.
• Vessels that are 26 feet to less than 40 feet in length must carry a hand- or power-operated horn capable of producing a blast that is audible for at least one mile. The vessel also must carry a bell.
• Vessels that are 40 feet or more in length must carry a power-operated horn or whistle capable of producing a blast that is audible for at least one mile. The vessel also must carry a bell.

These requirements apply to vessels operating on federally controlled waters.

• Vessels less than 39.4 feet (12 meters), 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.
