Sound-Signalling Devices and Appliances
The Small Vessel Regulations require that all boats carry some form of sound-signalling device, such as a whistle or horn. The requirement depends on your type and size of boat. Approved sound-signalling devices and appliances must be audible for a minimum of 0.93 km.
Sound-signalling devices are used to signal distress or your need of assistance, to alert other boats of your position in poor visibility and for navigation purposes.
Types of sound-signalling devices include:
- Mechanical (floatless) whistle
- Horn
- Portable compressed air horn
- Bell (required if your boat is greater than 20 m)
You should attach a Marine Blast Whistle to your lifejacket or PFD so that you’ll be able to signal for help if you become stranded in the water.
