Another title of the Anatomy of the Series - this one is some sort of tribute to Lawhill, the last of those great barques that made a living in the last century. Though the ships in question have almost disappeared from the world's oceans, there are still some of them remaining - they are either moored as museum ships or converted to the sailing ships used for training the future seamen. This collection compiled by three authors - Kenneth Edwards, Roderick Anderson and Richard Cookson, contains so much of valuable contemporary material like records, drawings and images, making this volume a very useful reference book for any naval history enthusiast.

For most of the people interested in marine history, these barques are mostly associated with the famous grain races of the past. The four- and five-masted ships were the ultimate sailing vessels, and the one to which the present book is dedicated, Lawhill, was one of the largest barques. This is definitely the must-have book and one of the most important and informative ones for every naval enthusiast interested in the last days of the greatest sailing vessels. We do recommended it to everyone as we recommend any other Anatomy of the Ship publication.

The present book of selected electronic projects is representing some of the best projects that appeared in the popular "73 Magazine". In this single volume the electronics experimenters will find various interesting projects - note that it will be also interesting to the radio enthusiasts and, in fact, literally anyone having an interest in electronics.

The projects included in this publication are covering all fields of electronics - from receivers to transmitters and from power supplies to testing equipment. The readers will even be able to construct some of the equipment themselves, just following the detailed instructions provided in the book. The authors have even included several simple projects for the beginners. The original intention of the authors was to provide all enthusiasts of electronics with a good compilation of tried, tested and proven electronics projects.

Five major chapters of the publication address power suppliers and power regulators, general testing equipment, special testing equipment, amplifiers, and receivers. Definitely recommended volume to anyone making his first steps in the amazing world of electronics, since it is really dealing with all important areas of electronics - it means that the readers will be given a good chance to apply their theoretical knowledge and may try to do something real.

More than a century ago, B. Helland-Nanses and I. Snadstrom and proposed a method of computing the ocean currents on the basis of the water density distribution. Later, this method became known as the dynamic method for computing elements of the ocean currents, or hydrological data analysis method.

This is the indirect method and fully bases on the theoretical assumption that the coriolis force and horizontal pressure gradient are in equilibrium in the steady state below the mixed layer of the ocean surface. The velocities of the current are calculated by means of the dynamic method. The present volume is the author's attempt to properly justify the method referred to above, theoretically and also to shed some light on the nature of currents calculated/computed using this method.

It also examines the importance of the depth of reference surface and the accuracy of the computations. In addition, the book contains the descriptions of the structure of the gradient component of a wind-driven current velocity.

However, the author of the title does not attempt to provide a thorough treatise on the method in question, but is rather trying to analyze some of the important aspects of the theoretical principles of the dynamic method together with the possible practical applications, using the ocean currents theory. 

This thorough and very interesting study performed by David White has been based on the Admiralty Collection in the Draught Room of the National Maritime Museum. There are about eight thousand detailed draughts in this collection, of which roughly one-quarter relate to frigates. Thirty-eight of these ships belong to the Artois class and, according to the catalogue, ten of them represent Diana. But, we cannot say this is correct. Draught number 1883, the sheer draught, is the original Navy Board copy for building the class and has several projected modifications overdrawn on it-one of them for a thirty-six-gun version.

The inside and outside planking expansions, under the draughts reference numbers 1884 and 1884A, remain mysteries. They are dated 'Deptford Yard 14 May 08' and as far as can be ascertained no ship of the class was ever in the state depicted. Circumstantial evidence in other fields points to them being academic exercises only. Many other channels have been explored and re-explored in order to obtain accurate and authentic information to present it to the readers. Some of the major ones are listed at the end of the Introduction under the heading 'Sources'. To list them all would require a further volume.

The present study was prepared and released with the original intention of its author, Peter Goodwin, to provide the readers with the precise and very detailed info relating to the construction and fitting of the English naval vessels of the period 1650-1850. According to many reviews done by the naval history enthusiasts, the volume is an outstanding reference source for any person with the need for the detailed info on those warships.

The text part of the book has been profusely illustrated with the drawings plus photographs of the models of the vessels as well as of those in physical existence. The author of this title has managed to cover every single aspect of the hull construction and also provided detailed technical description of both internal and external hull fittings. And, particular and close attention has been paid to the changes and developments over the years - they have been provided along with the approximate dates at which they have been generally accepted.

Another unique feature of this book is that it provides numerous extensive data tables as well as the formulas allowing readers to perform the accurate reconstruction of the dimensions of the warships together with the correct placement of the hull components for a very broad range of vessel types and sizes. We would recommend this publication to be contained in the working library of any person with the interest in construction and workings of the English naval ships of the past.

Geometry is the discipline directly dealing with the properties and measurements plus the relationships of the points and their sets. Vessels and other marine structures are really large and usually quite complex objects therefore the final success of their planning and further production mostly depends on proper geometric descriptions of the components they usually consist of, as well as on their positional relationships.

Traditionally, a 3D models of representation are utilized, and particularly at different scales and lesser levels of details in comparison to the actual objects. The process of producing real products commonly consumes large quantities of the material, human and time resources which will of course be considered wasted should the final result of this production process be functioning not in a way it was originally supposed to function.

This volume covers the most important aspects of the ship geometry, such as the geometric modeling as applied to the marine design, coordinate systems, geometry of curves/surfaces, subdivision surfaces and geometry of solid objects, polygon meshes, definition of the hull surface, weight/displacement, form coefficients of the ship hulls, hydrostatic analysis, capacity and arrangement issues including tonnage, subdivision of the compartments, tank and container capacity, decks and bulkheads as well as superstructures and hull appendages...

This nice and captivating marine novel by Peter Tonkin is actually a sequel to his very popular thriller "The Coffin Ship". The characters of this novel book, Richard and Robin Mariner are having a rare vacation and suddenly stumble upon a plot of the terrorist organization to strangle the oil flow out of the Persian Gulf. Some eight years after the previous set of adventures they have all been again caught up in a mystery happening around huge supertankers.

They now discover a "fire ship", i.e. one full of explosive materials and designed with the aim to destroy all vessels around it. In the meantime, their supertanker Prometheus II is under terrorists attack, and Robin's father is kidnapped in the Persian Gulf when he arrives with the clear intention to manage the situation. The vivid and colorful descriptions of the maritime life and the sea by the author, together with the swift pace of the action has made this a really gripping marine novel.

The main characters of the novel have to display their best merit to overcome all obstacles, avoid all bullets, but this has never been a drawback to a really good thriller. An interesting and fascinating story that will be definitely found a great one by all lovers of sea.

Humans have done sufficient damage to every habitat that the bells can always be heard, but we seek to place emphasis elsewhere. How can an audience focus on a drama's denouement until they're invested in the players? Where they live? Who they live with? The conflict and beauty of their lives? Hence our focus on the characters in the oceans, the lives they lead, and the tactics they use to thrive.

We have tried, in our chapters, to bring these characters to life by combining a novel's narrative flair with the scientific accuracy that these subjects demand. And we chose the sea's most extreme life to show what life is fully capable of. We apologize for inaccuracies that may still be present: despite a worldwide network of friends and colleagues, a survey comprising more than 200 topics will never be perfectly accurate while research is ongoing and new results are arriving.

Throughout, we used the scientific literature as the foundation of fact on which our narrative is built—but good storytellers also try to show their subjects in living color, in dynamic movement, and in life and death. And for these elements we sometimes constructed scenes that are fully consistent with the data but may not yet have been witnessed...
