Preface
The search for mechanisms to reduce boat and ship hull resistance is one of the principal challenges of a naval architect, along with creating a shape that is stable in the face of wind and waves. Minimized resistance means minimized power and so maximizing potential payload by reducing the amount of fuel carried, leading also to minimizing operational costs and environmental impact. There is a limit to how much improvement one can make to the shape of a hull. The drag of a displacement ship is primarily due to friction over the immersed surface. Engineers have therefore studied ways to reduce friction since the mid-nineteenth century. The culmination of this work for displacement ships and barges has been successful implementation of systems using air bubbles, air layers, or cavities to reduce the friction over the bottom of large vessels. High-speed planing vessels have quickly developed since the World War II, as the technology for light and powerful diesel and gas turbine engines and lightweight structural hull materials such as welded aluminium alloy and
