Patent

CA 2359532

This invention provides an improved shape of the bow of a high speed ocean- going ship. It introduces a set of inverted and inclined surfaces that enclose the bow from above, and cause the hull to move through the waves rather than over them. These surfaces generate a downward lifting force that counteracts the displacement force. Displacement force causes a traditionally-shaped bow to lift above waves and initiate pitching movement. The new type of bow reduces or eliminates pitching movement and slamming loads on the hull, thus improving ride quality, and enabling designers to specify lighter structure under the existing rules. This in turn reduces the overall weight of the craft, enabling reduction in the power required to achieve the service speed, reduction in fuel consumption, and reduction in the associated capital and operating costs.
