Abstract
This report responds to the request by the South West of England Regional Development Agency (SWRDA) for an independent review of the work carried out by the Halcrow Group Limited, specifically that which dealt with coastal processes and the impacts of the devices on the inshore wave climate. Of high relevance is the impact on surfing in Cornwall. Other reviewed information was a scientific publication of Millar et al. (2006). Discussions with the industry, through a spokesperson, Mr Andrew Scott, of xx were held to more fully consider the wave height reduction in the lee of the Pelamis. New information and measurements were provided.
