Categories of waters

You should know what type of waters you will be operating your boat in because that determines the minimum safety equipment you must have.

Read the Marine Safety guide. This includes the type of personal flotation device or life jacket, that you must carry on your recreational boat.

  • non-tidal rivers
  • lakes
