Wave Wake Research AluminumNow's Partners & Colleagues have an ongoing research program into wave wake involving both model and full scale tests. Crowther Multi-hulls ferries have been operating in environmentally sensitive areas, such as world heritage listed national parks, for many years. Crowther Multi-hulls have developed a very low wash hull form over a long period of time, we do not claim a low wash signature as a knee jerk reaction to modern trends. While providing a low wash, the Crowther hull shape has a wide beam, providing a large internal volume. The benefits of this are multifaceted, more space for maintenance of machinery, more space for access during construction and a reduced draft. Crowther Multi-hulls are part of a cooperative research group investigating the wave wake characteristics of high-speed ferries.  We are involved with ongoing research projects that have been undertaken by three independent research organizations: The Australian Maritime College Ship Hydrodynamic Centre.  The Wolfson Unit, University of Southampton, England. The Australian Maritime Engineering CRC Ltd. Typically a  research project includes full-scale wave wake measurement trials and a series of towing tank model experiments. The Crowther hull shape creates a very low wash and meets all current national wake-wash regulations.  Some examples of our vessels successfully operating in environmentally sensitive regions, with strict wake wash criteria imposed, are: The 'Wanderer II' operates on the Gordon River, Tasmania, a world heritage listed region. The 'Te Hukatai' operates across Cook Straight, New Zealand and into a environmentally sensitive sound. The local governing authorities impose a strict international wake criteria developed by the Danish Maritime Authority. The 'Wanderer III' operates on the Gordon River, Tasmania, a world heritage listed region.
