In addition to life jackets being mandatory, you are also required to have a safety kit:
A bailing device to remove water from inside the watercraft. A hand-held bailer can be purchased or made by cutting the end of a bleach bottle.
A paddle or oar to help you control your craft.
A sound-signaling device to help with navigation, alerting others of your approach, or in case of emergency. This could be a portable air horn, whistle, mechanical whistle or bell.
A heaving rope or towing line (15 metres long) that floats to use for rescue or to pull your craft to safety.
Navigation or safety light to be used at night or in poor visibility.
