Sound Signal Devices

A sound-signalling device or appliance is essential in periods of reduced visibility, such as fog and heavy rain, or whenever a boat operator needs to signal his or her intentions or position. For example, sound signals are necessary when meeting head-on, crossing, or overtaking, and in emergency situations. The Small Vessel Regulations require you to carry a sound-signalling device or appliance.

The length of the pleasure craft determines which sound-signalling equipment—a sound-signalling device or a sound-signalling appliance—you must carry.

  • Sound-signalling devices are sound-making devices that are not fitted on the pleasure craft and include whistles, pealess whistles, air horns, etc.
  • Sound-signalling appliances are fitted on the pleasure craft and include whistles, horns, bells, and gongs.
