Experimental analysis of catamaran forms with bulbous bows operating in shallow water
Experimental analysis of catamaran forms with bulbous bows operating in shallow water
In recent years fast ferries which are capable of speeds in excess of 40 knots have been operational in water of depth of less than 10 m. As high-speed operations near sensitive shorelines increase, complaints from the public on extensive wave wake or wake wash from these fast vessels have increased. Although the leading waves in the wash are very small in terms of wave amplitude compared to storm waves, they have a very long period and build in height rapidly in shallow water at the shoreline thereby causing substantial surges on beaches as well as breaching sea walls at high tide. This wake wash is likely to have environmental effects such as shoreline erosion as well as endangering swimmers and small boats.

Abstract
In recent years fast ferries which are capable of speeds in excess of 40 knots have been operational in water of depth of less than 10 m. As high-speed operations near sensitive shorelines increase, complaints from the public on extensive wave wake or wake wash from these fast vessels have increased. Although the leading waves in the wash are very small in terms of wave amplitude compared to storm waves, they have a very long period and build in height rapidly in shallow water at the shoreline thereby causing substantial surges on beaches as well as breaching sea walls at high tide. This wake wash is likely to have environmental effects such as shoreline erosion as well as endangering swimmers and small boats.
