Breaking down the complicated concepts of speed, acceleration, torque, fluid mechanics, and surface physics, Physics of Sailing provides a lively, easily accessible introduction to the basic science underlying the sport of sailing. It illustrates the many ways physics can be used to understand the principles of sailboat propulsion and how a scientific understanding of the boat, wind, and water can lead to more skillful sailing. After a brief but insightful tour of the history of sailing, the book explores the physics involved in making faster sailing crafts for both upwind and downwind sailing, including Newton’s impact theory of fluid resistance and lift and drag phenomena. It compares possible sail shapes, presents measurements of hull smoothness, and describes wind turbulence, the nature of water waves, and the structure of wakes. Using the physics of optics, the author also explains the connection between water’s appearance and the wind. Along with a glossary of sailing terms, he includes many examples throughout to illustrate the concepts in practice. Avoiding unnecessary formalisms, this book skillfully applies the principles of fluid mechanics to sailboat technology and the art of sailing. It should help you become a more knowledgeable sailor.
Throughout history sailing has been instrumental in the development of civilization, affording humanity greater mobility than travel over land, whether for trade, transport or warfare, and the capacity for fishing. Sailing has contributed to many great explorations in the world. In 1889, Knight sailed to the island of Trindade off the coast of Brazil in a 64-foot cutter named the Alerte. He was in search of treasure. In The Classic Guide to Sailing, E. F. Knight, the soldier, journalist and war correspondent, relates some of his experiences and lays down the basic principles of sailing and boatcraft for the budding sailor.

The official learn-to-sail manual of the American Sailing Association and the United States Coast Guard Auxiliary, with over 150 line drawings and photographs. Written by America’s foremost instructional authority, the new edition of Sailing Fundamentals combines the training programs of the American Sailing Association and the United States Coast Guard Auxiliary. The official learn-to-sail manual of the American Sailing Association, it is also used in the programs of many yacht clubs, colleges, and sailing groups. Unlike most introductory sailing books, which reflect the biases and idiosyncrasies of their authors, Sailing Fundamentals has been extensively pretested by ASA professional instructors to ensure that it offers the fastest, easiest, most systematic way to learn basic sailing and basic coastal cruising. This book covers every aspect of beginning sailing—from hoisting sail to docking and anchoring—and specifically prepares the learner to qualify for sailing certification according to international standards. Widely acclaimed author Gary Jobson has won several major races, including the 1977 America’s Cup victory as tactician aboard Courageous. He was head sailing coach at the US Naval Academy, and has conducted sailing clinics across the country.

And who are the mysterious couple with the high powered motor boat who are to busy searching beneath the water to answer his call for help? Tony does some searching on his own. What he discovers leads him on a daring hunt for a 200-year-old shipwreck . . . and a dangerous confrontation with treasure hunters who will stop at nothing to keep Tony from learning their secret.
The Paranormal as Friend and Familiar (Real Life Experiences of a Spiritual Pilgrim)
Author: J. Harold Ellens
Publisher: Wipf and Stock Publishers
This volume presents the narrative of the author's personal spiritual journey, which is marked by numerous constructive life-changing paranormal experiences that can only be accounted for as special initiates of the divine spirit providing intimations and illuminations. These events are set in the context of the rich literature available, which reports similar events in the lives of many other persons, under both normal and extreme circumstances. The author, a clinical psychologist and pastoral theologian, interprets this broad panoply of psycho-spiritual data in terms of psychological science and biblical perspectives. He concludes that the divine spirit is pervasive throughout the universe and present in all the dynamics of life forms, constantly endeavoring to communicate with humans. Thus, the paranormal may well be more normal than the normal human experience and the veil between time and eternity, between the mundane and transcendent worlds, and between life and the life to come is apparently more permeable in both directions than we suppose.

How the Earliest Mariners Unlocked the Secrets of the Oceans
Author: Brian Fagan
Publisher: Bloomsbury Publishing USA
In Beyond the Blue Horizon, bestselling science historian Brian Fagan tackles his richest topic yet: the enduring mystery of the oceans, the planet's most forbidding terrain.This is not a tale of Columbus or Hudson, but of much earlier mariners. From the moment when ancient Polynesians first dared to sail beyond the horizon, Fagan vividly explains how our mastery of the oceans has changed history, even before history was written. Beyond the Blue Horizon delves into the very beginnings of humanity's long and intimate relationship with the sea. It willl enthrall readers who enjoyed Longitude, Simon Winchester's Atlantic, or in its scope and its insightful linking of technology and culture, Guns, Germs, and Steel. What drove humans to risk their lives on open water? How did early sailors unlock the secrets of winds, tides, and the stars they steered by? What were the earliest ocean crossings like? With compelling detail, Brian Fagan reveals how seafaring evolved so that the vast realms of the sea gods were transformed from barriers into highways that hummed with commerce. Indeed, for most of human history, oceans have been the most vital connectors of far-flung societies. From bamboo rafts in the Java Sea to the caravels of the Age of Discovery, from Easter Island to Crete, Brian Fagan crafts a captivating narrative of humanity's urge to seek out distant shores, of the daring men and women who did so, and of the mark they have left on civilization.

Even as airlines provide faster means of travel, ships and boats remain as important as ever in transporting passengers and cargo across the worlds bodies of water. While ship design has become increasingly sophisticated with time, everything including the luxury liners, warships, and sailboats of today owe much to the watercraft that facilitated travel, trade, and war among ancient cultures. This detailed volume examines the development of the different types of water vehicles and the design of related structures, including docks and quays.

Nathan Talbot participated in the 1936 Olympics, as captain of the Tyrian Tempest, representing the United Kingdom in the 6-Meter Class Yachting races. The competition was fierce and even though Talbot was a skilled sailor, he was disappointed with only winning the Bronze Medal, outmaneuvered by the German sailing master Werner Grossman. However, there were other darker issues plaguing the young Englishman once he returned from Nazi Germany. Something sordid and dangerous was simmering underneath all the pomp and circumstance of the new Fatherland. Less than four years later, Nathan's concerns were realized, as Germany plunged the world into yet another war. This time, Talbot took command of a Motor Torpedo Boat (MTB) and this time set sail for combat in the English Channel. Nathan was soon to discover that his old nemesis, Werner Grossman, had been given command of an entire E-boat flotilla operating in the same area. Then one night, while Talbot was sneaking about Occupied France, he literally ran into 19-year-old Elise Dub and it was love at first sight. While taking daring risks to keep the flames of romance burning, Talbot was also assigned to British Intelligence. It seemed that the former yachtsman's first-hand experience with French ports would come in handy for more covert reasons. There was just one problem. It also became obvious that Herr Grossman had also been captivated by Elise Dub's charms and planned to seduce her. Failing that, the German officer had every intention of forcing himself upon her. While the war at sea was often decided with lightning speed and brutal results, World War Two became incredibly personal for Nathan Talbot, who would stop at nothing to rescue his true love.
