The Development Of The Rudder

Far exceeding anything ever before written on the subject, The Development of the Rudder endeavors to unravel the mysteries of the evolution of a vital piece of seafaring equipment. And in the process, Lawrence V. Mott answers far-reaching questions on why some technologies develop and endure, while others are soon replaced. In this first considered historical overview of the rudder, Mott begins his examination in the Roman period, and from there traces rudder development through the middle centuries to the age of exploratory navigation, by which time the quarter-rudder had been replaced by the pintle-and-gudgeon rudder. Throughout, he offers a thorough analysis of the mechanics of these rudder systems, while never losing sight of the human interest that attends the radical changes brought on by innovation. The layperson will find in this unique work a penetrating look into the history of technology at sea - a history that defies the linear cosntructs often associated with developmental and evolutionary theory. Maritime historians, nautical archaeologists, and ship modelers will embrace this book as an invaluable reference, which includes useful appendixes filled with technical data for researchers and scholars.

The course keeping and manoeuvring requirements for a ship are governed by international maritime law. In assessing and predicting the course keeping and manoeuvring capabilities of the ship, knowledge is required of the rudder forces necessary to keep a course or facilitate a manoeuvre. The second edition of Marine Rudders, Hydrofoils and Control Surfaces includes up-to-date data and rudder design techniques that enable the rudder forces to be estimated, together with any interactions due to the hull and propeller. The new edition describes the design and application of hydrofoils including shape adaptive design, and their applications including hydrofoil craft, yachts, and kite surfing hydrofoils. The professional will also face the need to design control surfaces for motion control, such as roll and pitch, for surface vessels and submersibles, and the book contains the necessary techniques and data to carry out these tasks.This book is for practicing naval architects and marine engineers, small craft designers, yacht designers, hydrodynamicists, undergraduate and postgraduate students of naval architecture, maritime engineering and ship science, and the broader engineering community involved in the development of marine craft that rely on the generation of ‘lift’ such as control engineers and aerodynamicists. Describes techniques for analyzing the performance characteristics of rudders, hydrofoils, and control surfaces Includes extensive design data and worked examples for the analysis of rudder, hydrofoil and control surface performance Provides a detailed examination of the design of hydrofoils

The Maritime Engineering Reference Book is a one-stop source for engineers involved in marine engineering and naval architecture. In this essential reference, Anthony F. Molland has brought together the work of a number of the world's leading writers in the field to create an inclusive volume for a wide audience of marine engineers, naval architects and those involved in marine operations, insurance and other related fields. Coverage ranges from the basics to more advanced topics in ship design, construction and operation. All the key areas are covered, including ship flotation and stability, ship structures, propulsion, seakeeping and maneuvering. The marine environment and maritime safety are explored as well as new technologies, such as computer aided ship design and remotely operated vehicles (ROVs).Facts, figures and data from world-leading experts makes this an invaluable ready-reference for those involved in the field of maritime engineering.Professor A.F. Molland, BSc, MSc, PhD, CEng, FRINA. is Emeritus Professor of Ship Design at the University of Southampton, UK. He has lectured ship design and operation for many years. He has carried out extensive research and published widely on ship design and various aspects of ship hydrodynamics. * A comprehensive overview from best-selling authors including Bryan Barrass, Rawson and Tupper, and David Eyres* Covers basic and advanced material on marine engineering and Naval Architecture topics* Have key facts, figures and data to hand in one complete reference book

Marine Rudders and Control Surfaces guides naval architects from the first principles of the physics of control surface operation, to the use of experimental and empirical data and applied computational fluid dynamic modelling of rudders and control surfaces.The empirical and theoretical methods applied to control surface design are described in depth and their use explained through application to particular cases. The design procedures are complemented with a number of worked practical examples of rudder and control surface design. • The only text dedicated to marine control surface design• Provides experimental, theoretical and applied design information valuable for practising engineers, designers and students• Accompanied by an online extensive experimental database together with software for theoreticalpredictions and design development

This volume examines the development and evolution of the war galley known as the Dromon, and its relative, the Chelandion, from first appearance in the sixth century until its supercession in the twelfth century by the Galea developed in the Latin West. Beginning as a small, fully-decked, monoreme galley, by the tenth century the Dromon had become a bireme, the pre-eminent war galley of the Mediterranean. The salient features of these ships were their two-banked oarage system, the spurs at their bows which replaced the ram of classical antiquity, their lateen sails, and their primary weapon: Greek Fire. The book contextualizes the technical characteristics of the ships within the operational history of Byzantine fleets, logistical problems of medieval naval warfare, and strategic objectives. Surviving Byzantine sources, especially tactical manuals, are subjected to close literary and philological analysis.

Drawing upon Arabic literary sources, iconographic evidence and archaeological finds, this book examines trade, port towns, ship construction, seamanship, ship typology and their historical development in the Western Indian Ocean, focussing on the Medieval Islamic period but including earlier sources.
