Guide to Low Wave Wake - "Wake Up Slow Down"

Is your boat wake or prop wash causing erosion problems? This leaflet explains how and why it happens – and what you can do to minimise the damage.

What’s the problem?

The soft banks and beds of many Tasmanian waterways are vulnerable to damage from boat wake and prop wash. Easily affected landforms include estuaries, inlets, lakes and lagoons – places where natural wave energy tends to be low.

Banks of peat or mud, shallow lagoons or lakes with muddy beds and sandy deposits in upper estuaries are all areas of risk. Wake striking the banks can cause rapid and severe erosion, exposing the roots of vegetation and causing the banks to collapse. Wake impact and prop wash can also churn up the sediments, degrading the aquatic environment for plants and animals.
