This workbook is designed to accompany the text Modern Marine Weather by David Burch (First or Second Edition). It can also be used by those who have learned marine weather from other sources. It provides questions and answers for all aspects of marine weather. This workbook is used in training programs around the US. These are practical questions that every mariner should know the answer to. It is a through overview of the subject. Anyone who answers all of these questions can be confident that they have a firm and practical grasp of marine weather that will enhance their interpretation and...

This Book compliles Current Charts and Tide Prints for Puget Sound. Current Charts show the values of the currents at each reference station. There is one chart for every hour throughout the cycle. They are indexed to the tidal current at Admiralty Inlet. Tide Prints show the flow patterns and how they evolve throughout the current cycle. There is one print for every 3 hours throughout the cycle. They are indexed to the tide height in Seattle. Comparing Tide Prints and Current Charts shows the locations of eddies and bands of current, and how these bands and eddies move and interact as the...

The barometer remains the most important tool for evaluating and predicting the weather. This book explains why knowing accurate values of the atmospheric pressure can improve this process and benefit all applications. Ways to evaluate and calibrate aneroid and electronic barometers using readily available data by Internet or telephone are clearly described. Tactical applications to marine navigation are covered. The book also includes worldwide average monthly pressures and their standard deviations. With the exception of trained meteorological crews, barometers in the past were used at sea...

"Das lange vergriffene Kultbuch von David Burch, einem der weltbesten Navigatoren und Grunder der Starpath School of Navigation, nun auf Deutsch neu erschienen. Kein Survival-Handbuch, sondern ein umfassendes Werk uber die eigentlichen Grundlagen der Orientierung auf See, von den polynesischen Sternenpfaden bis zum Steuern nach dem Wind und nach Wellenbildern. Wenn die Technik teilweise oder zur Ganze versagt sollte der verantwortungsbewusste Skipper oder Navigator zumindest einige der hier aufgearbeiteten Grundlagen um Kopf haben. Ein leicht verstandliches Standardwerk fur alle, die sich mit...

Sextants are used to measure angular heights of celestial bodies above the horizon to find the latitude and longitude of the observer. They can also be used on land with artificial horizons. Sextants can also be used to find the correct Universal Time by measuring the angular distance between the moon and another body along its path across the zodiac. In coastal waters or on land, sextants can be used for very accurate piloting by measuring the horizontal angles between charted landmarks. The vertical angle of a peak above its baseline determines the distance to it, which, combined with a...
