The Mc-deM Surf Hazard Rating (SRH) Model was developed by Bond University professionals* in partnership with surf lifesaving as a surf conditions rating tool to assess the prevailing conditions and, particularly when used to assist decision makers, to make informed decisions regarding risk management practices and the use of personal protective equipment (PPE) in events involving the use of surf craft.

A description of the SHR system may be found on the SLSA website.

Detailed usage of the system is located in relevant discipline sections of this Manual.
