This clear and accessible introduction to coastal navigation outlines most of the techniques of piloting that are still fundamental to safe navigation even with modern electronic aids. Step-by-step, the reader is guided from simple to more complex piloting solutions. In addition to dead-reckoning techniques, the author covers tides and currents and explains how to use LORAN C and GPS. There are numerous illustrations throughout the text and practice problems at the end of each chapter. Key Advantages: fully updated new edition, perfect for sail and power, clear layout and instructions, comprehensive overage of all aspects of coastal navigation, review questions and answers, and suitable for self-study and Coast Guard or other similar courses.
This book is primarily intended as a companion volume to a shore-based navigation course where there are no extraneous distractions. The pages which follow work towards making you into the sort of small craft pilot who can pick up any boat, anywhere in the world, whatever the conditions, however strong the currents, however large the tides, and operate it with confidence. Learn all this material thoroughly while you have the chance, then take it afloat and put it into practice. With sound ground work, you will find that skilled navigation at sea poses no problems at all, and that confidence in where you are and where you are going will free your mind to concentrate on the great pleasures of skippering your yacht.
Coastal Navigation for Class and Home Study is based on the notes prepared for students by the author during some 20 years of teaching navigation, initially to private or commercial pilots, and then to sailors and professional mariners. The book is copiously illustrated with graphics which explain chart projections, scales and symbols, and describe lights and other navigation aids. It demystifies the True, Magnetic and Compass Norths as well as problems of time, speed and distances, and explains how to plot courses and take bearings, or draw regular and advanced Lines of Position using the international system of labeling. The book further clarifies the use of vectors to easily determine the impact of a current on the boat speed and direction, and goes on to show how to evaluate tides and currents. The final sections describe the use of GPS and electronic charts, highlighting their limitations. Additional notes and explanations are given in the areas where students traditionally experience difficulties, as well as supplementary examples and exercises. The companion book, Coastal Navigation Exercises, offers all the exercises needed for practice.
Studies of marine ecology have traditionally been approached through lectures and field courses devoted mainly to intertidal and inshore habitats, and it is surprising in these days of increased awareness of man's environmental impact that so little attention has been given to integrated approaches involving the whole coastal zone and including the terrestrial part, which is man's major habitat. The coastal zone has been the subject of extensive investigation, not only because of its biological diversity and accessibility, but also because of its economic and aesthetic importance to man. This book is written with the intention of providing a concise but readable account of coastal ecology for advanced undergraduates and immediate postgraduates. We have adopted a habitat-organismal ap proach because we believe that a knowledge of biota and major features of their environment is the best key to an understanding of both larger-scale processes, such as energy flow and nutrient cycling, and smaller-scale but equally fundamental processes, such as behavioural and physiological ecology. Examples have been selected from polar, temperate and tropical regions of the world. The breadth of the subject has dictated selectivity from sources too numerous to acknowledge individually, but we have included an up-to-date reference list for the main subjects of each chapter.
Ireland is an island surrounded by ocean, with a high percentage of its population living in the coastal zone and has often been referred to as an "island nation". The importance of the coastal zone to Ireland is extremely high, given its economic value from tourism and recreation, fishing, aquaculture, renewable energy, ports and linked industries, as well as its environmental significance. Proximity to the sea has also profoundly influenced Ireland's history, culture and multiple identities. Although there are existing guides about Ireland's coastal geology, physical geography and landscapes, these are fragmented and mostly of a local nature. "Shorelines: The Coastal Atlas of Ireland" will aim to fill this gap by looking at the coastline of the entire island of Ireland as a whole, from the physical, human and environmental perspectives.The Atlas will contribute towards the dissemination and outreach of scientific knowledge about the coasts of Ireland and of the processes that are shaping them, to the broader public, government and decision makers. The Atlas is relevant globally, to all those that are interested in coastal matters and the work is not just about Ireland, but Ireland, as an analogue for many of the world's coasts.Visually stunning, accessible and an academic tour de force, this Atlas will resonate with everybody who has a connection to Ireland and anybody interested in the Irish coast.
There has been a recent increase in clashes between warships asserting rights to navigate and states asserting sovereignty over coastal waters. This book argues for a set of rules which respect the rights of coastal states to protect their sovereignty and of warships to navigate lawfully, whilst also outlining the limits of each. The book addresses the issue of the clash between warships and states by considering the general principles applying to use of force in the law of the sea and the law of national self-defence. It focuses on the right of coastal states to use force to prevent passage of warships which threaten their sovereignty, with particular reference to the specific maritime zones, as well as by warships to ensure passage or to defend themselves. The book also assesses the extent to which the law of armed conflict may be applicable to these issues. The conclusion draws together a set of rules which take account of both contemporary and historical events and seeks to balance the competing interests at stake. Providing a concise overview of the enduring issue of freedom of navigation, this book will appeal to anyone studying international law, the law of the sea, security studies and international relations. It will also be of interest to naval, coast guard and military officers as well as government legal advisors.

Sailing Made Easy is the first step in a voyage that will last you the rest of your life. It is a gift from a group of dedicated sailing professionals who have committed their lives to sharing their art, their skill, and their passion for this wonderful activity. This book, which Sailing Magazine called "best in class" upon its release in 2010, is the most comprehensive education and boating safety learn-to-sail guide to date. It is also the official textbook for the ASA Basic Keelboat Standard (ASA 101). Incorporated in the textbook are useful illustrations and exceptional photographs of complex sailing concepts. The text’s most distinguishing feature is its user friendly "spreads" in which instructional topics are self-contained on opposing pages throughout the book. There are also chapter end quizzes and a glossary to help those new to sailing to navigate their way through the extensive nautical terminology.
There are two types of electronic charts: raster navigational charts (RNC) and electronic navigational charts (ENC). RNC are exact copies of paper charts and their use underway comes naturally to navigators accustomed to paper charts. All traditional paper charts, however, and their RNC are being discontinued by NOAA. Many are gone already and all will be gone in a year or so. ENC (also called vector charts), on the other hand, include much more information than RNC; they allow user-selected display options that enhance safety and efficiency; and they are easier to keep up to date. But they do not look like traditional charts, and they do not behave like traditional charts. Navigation with ENC is fundamentally different from navigation with paper charts or RNC. Electronic charting benefits all mariners, professional and recreational, large vessels and small, power and sail, racing and cruising. The unique information in this book should help mariners in any of these categories master the use of ENC to enhance their safety and performance underway. There are many virtues of ENC, but to take advantage of these, a new approach to "reading charts" is called for. This book explains and illustrates the process. From the Forward to the Second Edition Two primary factors have taken place since the first edition that affect the content of this book. Foremost is the ongoing NOAA program to redesign the layout of all ENC to make them more consistent amongst themselves and with the ENC from other nations. This is a major improvement. The process is called rescheming. The most apparent changes are the shapes and coverages of the individual charts, which, when reschemed, become regular and consistent. Chart scales and depth contour conventions are also improved, plus we get a larger (more detailed) compilation scale for many areas. On top of these changes, the USCG has just completed a call for comments on the proposed new ruling that vessels must have some electronic chart viewer on board to effectively read the official ENC. In other words, we are at the moment when ENC have gone from an optional substitute for paper charts to being a required method of navigation. With all of this going on, we can see why NOAA decided it was time to take on the daunting task of rescheming all of the US ENC. We have added an appendix on rescheming to cover the details of the changes and how we recognize them in conjunction with what we now call the legacy ENC that exist before rescheming. The full conversion will take some years to complete, so we will be using the legacy ENC layouts for quite a while to come. The interpretation and basic use of ENC does not change with the reschemed charts. When a topic comes up in the book that is affected by rescheming, we make note of the changes with a reference to the appendix. There is also a short appendix on the new NOAA custom chart program (NCC); another on Inland ENC, the US Army Corps of Engineers charts for the Western Rivers; and one emphasizing a recommended vessel icon set up for navigation in strong wind or current. An overview of the next generation ENC called S-100 has also been added as an appendix. The second primary factor that has led to updates in this edition was the preparation for and first experiences we have had with our new training course on Electronic Chart Navigation. Many sections throughout the book have been enhanced to reflect the practical experience we gained. Interactions with students first learning a new subject is an invaluable resource we are lucky to have. Topics with more extensive updates include: coverage of the Quality of data object and Zone of Confidence attributes; treatment of magnetic variation; use of safety contour and safety depth; plus a new section on the use of encrypted S-63 charts with a specific example using the newly free ENC from New Zealand.
