An Azimuthing Stern Drive (ASD) tug or towboat is a high-performance vessel that is responsive, quick to maneuver and extremely powerful. In the hands of a skilled operator maneuvering these vessels looks effortless and seamless—smoothly spinning around, nimbly shifting position, having pinpoint control, all while the operator's hands move the control handles instinctively and naturally. This book takes the reader through an efficient learning sequence leading to that level of proficiency. Text, illustrations and practice drills create a clear understanding of ASD maneuvering principles and assist the reader in acquiring the intuitive hands-on feel required to operate these vessels. Each chapter covers a basic maneuvering element—steering, managing speed, stopping, hovering, lateral movement—and their application to light boat, barge and ship handling. This book is the first step for a professional mariner adding a new competency to his or her art of towing—driving a Z-drive.

An Azimuth Stern Drive (ASD) tug boat is a high-performance vessel that is responsive, quick to maneuver, and extremely powerful. This workbook is designed to facilitate learning, through both intellectual and hands-on presentations. It teaches a clear understanding of ASD tug maneuvering principles and assists the reader in acquiring the intuitive feel for operating the tug. Text and illustrations provide exercises recommended to build the hands-on knowledge. The book covers the basic elements of maneuvering an ASD tug, through steering, speed, turning, stopping, hovering, and lateral movement. Each chapter provides questions to test and strengthen the skills.

Shiphandling with Tugs, Second Edition is the most comprehensive text available for the mariner who wants to learn how to safely and effectively operate tugs in assisting ships to and from their berths in ports and anchorages. Captain Jeffrey Slesinger used his extensive knowledge of the industry to bring Reid’s original edition, published in 1986, up to date with current technologies and standards, adding sections on the advances made in tug design, and line and winch technology. Shiphandling with Tugs, Second Edition includes a new chapter on ship escort with updated and expanded chapters on today’s tugs, including descriptions and illustrations of the latest tractor tug designs and capabilities.

A wide-ranging work on all aspects of towing, in both inland and ocean waters. Part I, The Industry, gives an overview, followed by descriptions of types of tugs and modes of towing. Part II, Operations, covers getting the tug under way, under way with tow and at sea, and special types of towing. Part III, Towing as a Business, deals with the shore establishment. More than fifty appendices consolidate data helpful to the tugmaster. The text is illustrated with more than 300 drawings, photographs, diagrams, and other visual aids.

They are the small strong ships without which the huge freighters cannot get into the harbour: Harbour tugs. Their versatility and power make them popular replica objects for model builders time and again. In this book, harbour tug specialist Stefan Thienel describes the special features of the great prototypes - and that is far more than just pure power. Among other things, the special drive systems, and the sophisticated winches with which the tugs are equipped to perform their tasks are described here in detail. The construction of a modern harbour tug as a highly detailed model then rounds off this book. The author guides the reader from the construction of the hull, through the numerous details, to the ageing, so that the model acquires the typical working ship character. An absolute standard work - not only for harbour tug fans! From the content: • Development of tugboat navigation • Original technology • Types of tugs • Tug design • Towing manoeuvres • The model • Tractor hull • Drive concepts • Towing winch and towing hook • Superstructure and interior • Paintwork and ageing • Electrics and electronics • Driving manoeuvres

Real-time, interactive ship simulators limped onto the scene, in the wake of flight simulators, some years ago. The maritime industries have a long history of conservatism, but this is now changing rapidly. The information age has also swept over ships and shipping, and has been taken to heart to such an extent that, for example, flight simulators now cooperate with ship simulators and import useful new concepts and methodologies. The more than 50 papers contained in this book show what and why. Although traditionally conservative, the marine world is also traditionally international and this has not changed. The papers in the book are by leading authors from all over the world and provide a detailed snap-shot of the rapidly advancing state-of-the-art, together with pointers to the future. The overall theme of MARSIM '96 and therefore also of this book is: Vessel manouevrability and marine simulation research, training and assessment, and includes original papers on topics such as bridge resource management, distant learning and simulators coupled via The Internet, virtual reality, neural networks, rudder-propeller hydrodynamics, prime mover models, squat in shallow water, and many more.

Core Principles of Maritime Navigation introduces the main navigation concepts required by trainees and professionals involved in maritime operations. The book covers a wide range of subjects from wind, waves and depths to navigational marks and buoys, navigational techniques and equipment, passage planning, duties of the Officer of the Watch, berthing and anchorage. It is not intended to be a technical publication; rather, it aims to introduce core ideas and concepts in an accessible way for general readers, university students, cadets and for the continuous professional development of experienced seafarers.

This set of two volumes comprises the collection of the papers presented at the 5th International Conference on Maritime Technology and Engineering (MARTECH 2020) that was held in Lisbon, Portugal, from 16 to 19 November 2020. The Conference has evolved from the series of biennial national conferences in Portugal, which have become an international event, and which reflect the internationalization of the maritime sector and its activities. MARTECH 2020 is the fifth of this new series of biennial conferences. The set comprises 180 contributions that were reviewed by an International Scientific Committee. Volume 2 is dedicated to ship performance and hydrodynamics, including CFD, maneuvering, seakeeping, moorings and resistance. In addition, it includes sections on ship machinery, renewable energy, fishing and aquaculture, coastal structures, and waves and currents.
