Celestial Navigation in a Teacup

   The original intention of the author of this volume was to prepare a book that would be used as the useful self-teaching instrument for the people having a desire to learn more about the celestial navigation from both academic and practical points of view. The content of this volume will for sure interest the experienced marine navigators who have got tires of "turning the crank" with the navigation tables and who are willing to have some better technical knowledge of the subject. The author has intentionally not covered the old-fashioned methods implying utilization of the sight reduction tables together with the pre-computed solutions, taking into account the wide usage of the electronic calculators and computers. The reference has been made by the author to the H.O. 229 and H.O. 249 methods and the author presented the fundamental background as well as the equations enabling readers to perform their own calculations and come to the correct answers having a proper understanding of the process and using only the calculator, note that the scientific one will be required having the trigonometric and inverse functions. The book starts with the historical overview and some basic information, followed with the description of the concepts of celestial navigation, using the sextant, corrections commonly made to the measurements, sight reduction, lunars, star identification, and other topics considered important.

Pencil, Paper and Stars
   Though the electronic systems of marine navigation are commonly considered extremely reliable, it shall always be taken into account that, should they fail while the vessel is at sea, their repair on board will most probably be not possible at all. In addition, they require constant supply of electricity. What if it fails as well, leaving the vessel with no means of finding the position and chart plotting? Having no means of route planning, how will modern navigators continue their voyage in a safe manner? The present publication has been written in a very reader-friendly manner, providing interested readers, and in the first turn navigators, with a clear and practical yet quite simple to understand description of the navigation techniques which can be utilized in case the electronic navigation systems installed on their yachts fail. The book will demonstrate how to understand the core principles standing behind the techniques they are using, see those techniques explained with no complicated math required, employ these techniques and put them into practice, i.e. use every opportunity to make the passage safe and seamanlike. The content is pretty well-illustrated presenting a variety of classic marine navigational methods the sailors can use and showing how some simple devices can be made by the voyagers.

Lookout Training Handbook - NAVEDTRA 12968-D

   Lookouts are persons detailed to perform the observation of everything falling inside the assigned sector and to reporting of everything they see or hear from the subject sector to the OOD, standing for the officer-on-the-deck and the watch officer of the CIC, i.e. combat information center. Their work and proper reporting is considered critically important for both safety and efficiency of the vessel which is commonly based on the alertness and effectiveness of the people assigned. Lookouts usually perform their work, i.e. observation and reporting, being directly supervised by the OOD; it should be noted, however, that the OOD would usually delegate subject authority to the BMOW, i.e. boatsmain's-mates-on-the-watch who assign the lookouts to the particular sections and ensures that all of them have been properly instructed, duly clothed, well-equipped and relieved. The training of the lookouts is conducted by the CIC officers. Usually, the lookouts are first people to catch the danger therefore it is very important to properly choose the stations for the lookouts to be located and perform their observations. The lookout perform their assigned duties in accordance with the lookout doctrine of their vessel. The number of such stations will depend on the vessel type and whether it is peace- or war-time...

USCG - Celestial Navigation

   The original intention of the compilers of the present pamphlet was to provide readers with the enough practical knowledge they would require to observe and plot the celestial position lines in a correct ways, and also to be able to obtain any technical information commonly needed for completion of the celestial navigation day. In fact, the degree of proficiency that can be reached in the field of celestial navigation, depends on the practical experience of the mariners. However, the present volume provides readers with lots of useful information that can be related as a foundation on which the whole other knowledge shall be built, and using this information, the mariners will be able to make the celestial navigation a much more satisfying experience. Please note that the information n an data provided in this title shall be used for training purposes only. For many centuries, the mariners used the small and big dippers as a sort of guides as they always stayed in a same position. The star that did never seem to move at the sky was noticed to have a constant attitude and the mariners of the past used this to move north and south. We would not consider celestial navigation a dead art at all, even in the age of modern equipment and electronics. It is actually used to update the systems of electronic navigation and also used when there are ni any other means readily available...

Astronomical algorithms

   This volume is an excellent source of practical guidelines intended to be of use for the engineers, programmers and scientists who require to be dealing with the astronomical predictions or associated calculations. The readers are actually expected to have some mathematical knowledge, more than a basical, therefore this is not the best choice for the beginners. This cookbook of algorithms provides a huge number of numerical problems commonly coming up in astronomy. The content makes it easy for the readers to use the presented algorithms for coding. Note that you will have to study more than just one chapter of this volume to get full understanding of the astronomical problems because none of them is easy. The author has focused on the classical math astronomy, though he has also dealt with some of the astronomy-oriented math techniques, for example fitting curves and interpolation, data sorting etc. Astrophysics has not been addressed. Obviously, not all topics of math astronomy can be covered in a single volume so the decision was made by the author to select most important and useful ones for the inclusion in his work. The material is explained in a very clear and precise way helping reader to understand the algorithms.

The Evasion of Tropical Cyclones

   This title is mainly intended to serve as a practical guidance to measures to be taken in order to evade the Tropical Revolving Storms and how to "ride out" with the minimum possible damage in case you have found yourself in the centre or near such storm. This book by P. Vergroesen is intended to provide mariners with all required information. All navigators shall know which exactly information they require; however, it appears to be quite time consuming and also difficult to compile all relevant technical information and draw correct conclusions.  Trying to make this a bit easier, the author of the present booklet has brought all of the information and regular cyclone tracks in one monthly chart for all areas. The mariners can determine both storm track and speed using the results obtained during the consecutive observations. The first part of the book provides general information and addresses preparations to be made in advance, while the second is dedicated to the cyclonic areas, making closer examination of the strategic courses, weather reports and safety matters in different marine harbors. The remaining parts of the booklet deal with detecting/plotting of the tropical cyclones, illustrated divergents, cyclone navigation, defining the distance to and direction of the center, plus provides advice on what shall be done at ports when cyclone is passing.

Squat Interaction Manoeuvring

   As ti is clear from the title, this book is fully dedicated to the squat interaction; the interaction at sea has some resonances with same effects on land. For example, you must have noticed the sway that is usually felt when a car either passes or is passed by a large truck on a road, or the suction that is always created by high speed trains when they are passing through the stations as well as the ground effects usually experiences by the airplanes taking off/landing. In the marine sphere, the interaction is commonly caused at the time of the interaction between the pressure fields around the vessels. All ships on the water are in a state of balance and they are held at rest by the hydrostatic pressures; once the vessels starts moving, the dynamic pressures are added. When the ship is moving through the calm water, the transverse and diverging wave systems are generated caused by the dynamic pressures. When the pressure systems acting over the underwater hull of the vessel are affected in any was, the state of balance will change. The ship may go slower or faster, move off her course, rise on to the surface of the water, i.e. squat, or sink deeper into it. When a vessel moves from deep to shallow water, the closeliness of the seafloor will have direct effect on the ship hull pressures as the water gets more and more shallow...

Navigation with a Pilot

   The pilots are considered the critically important resources possessed by the marine navigators in the harbor approaches - they are professional ship handlers with a truly encyclopedic theoretical and practical knowledge of the local ports and harbor areas. Their presence is in many cases officially required by the local law or regulations. However, they are not formally treated as members of the bridge team; however, again, it shall be understood that they are extremely important specialists. In most cases they remain the advisors to the ship master, who, in turn, are retaining the full responsibility for the safety of the vessel. Note that they have been given full navigational responsibility in Panama Canal and Suez Canal. Pilots are professional navigators and deserve respect and require management. Maintaining the due balance of the above mentioned elements is Captain's responsibility, managing the MPX, standing for the master-pilot exchange. The main objective of the subject exchange is to inform the pilot about the main dimensions of the vessel, condition of the shipboard machinery and navigational equipment, and provide the pilot with all other relevant information that may be important for the safe planning. This publication will provide the readers with some basic aspects of navigating the vessel with a pilot...

Navigating in Ice

   Icebergs and floes are obstructing the shipping lanes; they are delaying the ship transit and creating serious hazards for the vessels and people on board. The above mentioned environmental conditions have already caused several famous maritime disasters, such as the sinking of the Titanic. Sea ice is always dangerous and treacherous. Even though nowadays rescue operations and less risky that they used to be in the past, the wise mariners always treat ice with respect and observe the basic principles of operation in a safe manner in the areas where sea ice is expected in Winter months. This publication aims to raise the overall awareness and also improve the safety procedures associated with the ice navigation. The authors of the book have managed to cover a broad range of issues relating to the ice navigation, including different ice and iceberg types, capabilities of your vessel, preparation to the voyage, working with the icebreakers and ensuring safe passage through the ice. This training package is expected to be of some help to the crew members making them aware of the potential dangers that may be met; it will also inform them about the relevant safety measures to be implemented and followed. The content of this volume will be helpful to all crew members of all vessels sailing into the ice-prone zones. Highly recommended to the Masters as well as to the deck and engineering officers of such ships.
