Definitions of waterways

The table and maps on this page detail the three categories of waterway in Victoria.

Both the rules relating to speed and distance from shore change and the types of safety equipment you must carry and/or wear depend on the type of waterway you are operating on.

The specific operating rules for each Victorian waterway are set out in the Vessel Operating and Zoning Rules (VOZR).
