One of the most frequently debated aspects of recreational boating in recent years has been the noise that the boats make. PWs create varying pitch noises that are often described as ‘annoying’. These noises can be exacerbated by certain patterns of use and increase when personal watercraft are used in a small area for extended periods of time and either operated close inshore or in groups.

What can be done?

In recent years the industry has made technological advances that has reduced sound emissions by between 50 and 70%, making modern machines fall somewhere between vacuum cleaners and city traffic (70-80decibels). However, the basic design of small fast jet powered craft, patterns of use and the continued use of older craft put a limit on what can be achieved. Management should therefore try to minimise noise impacts by distancing operations from sensitive populations or areas.

One source of noise that can be tackled is that produced when engines are started onshore prior to launching, and again after recovery to flush the engine free of salt water. This can be achieved by providing facilities at access points, or promoting sites which already have a supply of fresh water and sound baffling.
