This edition of the Pub. 151 supersedes all previous releases. The distances stated in the table are in nm (nautical miles). Most of those distances are representing shortest routes and sometimes longer routes taking advantage of the favorable currents. In some cases the increased distances are shown; subject distances are resulting from the navigation routes that have been selected in order to avoid the dangers to navigation, for example the ice.

The ports of departure have been listed in alphabetical order together with the distances to the ports of arrival that have been listed straight below them. The authors have also listed the distances to the appropriate junction points. In order to obtain the required distance, users first have to find the port of departure in the list and then select the port of arrival and distance below. In the majority of cases, the distances in to and return directions are reciprocal; however, it may happen that they differ due to the different routes used taking advantage of weather and currents, as mentioned above.

In order to get the distance over the route passing through the junction point(s) you will have to find and manually add all distances for all of the sections into which the original route has been divided. The book contains charts that show the general routes, junction points in Atlantic, Indian and Pacific Oceans, and conversion tables...

This latest release of the World Port Index, i.e. Publication 150 traditionally provides all interested parties, and mariners in the first turn, with the locations and characteristics as well as the known facilities and available services of the major shipping ports of the world, together with the shipping facilities, oil terminals and other valuable information; the total number if the entries reaches sixty-four thousand.

As always, this release of the Publication cancels the previous one. The selection of the shipping places for the inclusion in the Index is based on the special criteria that have been established by the Agency. Note that they are not random choices. The information about each of the places has been supplemented with the sailing directions and charts, as applicable. The present release of the document includes all information that is currently available to the Agency as of the publishing date.

Taking into account a huge amount of the diversified information and data to be included in the single book, the authors has used some simple codes to indicate certain types of the information contained. All of those code symbols have been explained at the tops of the pages. Needless to say, this publication is there among the top important ones for all mariners regardless of their position.

Obviously, the most serious test of the buoyage systems occur once the mariners have been  directly confronted by the light marking some uncharted danger, for example a recent ship wreck, and particularly it this happens at night or in the conditions of low visibility. That is exactly the time when mariners must make the immediately, correct and positive decisions.

The very beginnings of the uniform buoyage system emerged more than a century ago when some of the countries did agree on marking of the port side of shipping channels with the can buoys of black color; the starboard hands, in turn, were marked with the conical buoys of red color. However, this caused some discrepancy between the ways of using and marking the buoys in Europe and North America. There have been several conferences held on this matter to work out a single buoyage system, however without any significant success until 1936 when one of the proposed systems was agreed.

Again, some of the countries did not become signatory to the convention and developed their own, original and opposite buoyage systems. Long story short, all efforts have finally resulted in the establishment of the IALA system and its wide implementation all over the world. Note that in some parts of the planet the conversion to the IALA systems has not been completed yet...

Though the electronic ship navigation is relatively new area, it is becoming more and more common, and this particularly relates to the commercial shipping. The present title by Adam Weintrit was prepared to offer its readers a real wealth of detailed data and information covering the various systems of nautical charting, showing how they operate and answering the most of the frequently asked questions related to the various electronic charts such as the RNC, ENC or DNC and associated systems like ECDIS and ECS.

This is the very first resource providing so much details covering all facets of ECS and ECDIS and it will definitely service as the true Bible for the users of ECDIS. Note that this publication not only provides required technical information to be used for the training programs but shall also be used by the practicing engineers engages in the field maintenance of the ECDIS.

In addition, the volume will present a specific practical interest to the people required to know about the selection and implementation, as well as the operational use and benefits of the above mentioned systems. The management matters have also been covered in this publication. The authors preferred not to go too deep into the purely technical details of actual construction and working principles of ECDIS.
