The wave wake generated by large vessels has received high-profile research and regulatory responses in recent years. Conversely, recreational vessel wave wake can impact significantly on sheltered waterways, yet the sector receives little research funding and is often regulated with simplistic criteria. Small craft wave wake, comprising smaller waves and shorter periods, can be quantified adequately with fewer variables, opening the possibility for over-arching guidelines that are not site-specific. This paper analyses past small craft wave wake studies, including bank erosion studies, to determine which measures of erosion potential are the most descriptive. Past approaches using a single criterion are shown to be generally inadequate and often misleading. A multi-criteria approach has been adopted to ensure that all the erosive components of highspeed, small craft wave wake are accounted for. A possible implementation method is discussed.
