Fundamentals of Charts Usage in Navigation

The free online course on the use of charts in navigation, passage plan preparation, and features of the buoyage system.

Publisher: ADU
This free online course teaches you about the use of charts in navigation, as well as how current is steered. You will learn about the procedure for counteracting current and leeway, as well as important terms that are used in current sailing. You will also learn how to collect information for the passage plan, along with how to calculate the distance of the visible horizon of a light, and the distance of the visible horizon of the observer.

Description

The introduction to the use of charts is a free online course that begins by introducing you to the importance of charts as an integral part of navigation. You will learn about plotting positions, transferring position lines, the effect on the ship's course, and important terms that are used in current sailing. The course will introduce you to the concept of tidal stream, the tidal stream information, along with some related examples. You will also learn about the characteristics of the light, types of lights, the geographical range, luminous range, and the nominal range. The course will explain the last sighting distances, extreme range, and dipping distance of a lighthouse. The running fix and the process of running fix with current and leeway will also be covered in this course. The introduction to passage planning and the various aspects of effective appraisal needed to plan a passage will be highlighted. It will outline the division of the international association of lighthouse authorities (IALA) maritime buoyage system, along with the difference between the region A and region B system of the buoyage. The cardinal marks used in maritime buoyage system will be covered in this course.

The course then outlines the various stages in planning passage, the preparation of a passage plan, and how to collect information for the passage plan. You will also learn about the execution process of the passage plan, and the important tactics that can be used for the execution of the plan. The important points to be considered in order to achieve the benefits of the navigational equipment provided in the vessel for position monitoring will be highlighted. The course will teach you the application of the primary seacoast lights, secondary lights, colour of the light, and the sector light. The course will cover the characteristics of the demographical range, luminous range, and the nominal range. You will learn how to calculate the distance of visible horizon of a light, a distance of visible horizon of the observer, and geographical range of the light. You will also learn about the caution involved when making use of the luminous or geographical range of lights for fixing the ship’s position. The steps for finding the raising distance of light when the observer’s height of the eye is provided will also be covered.

Furthermore, this course will help you get familiar with the cardinal system, other buoys, distinguishing flashes and retro-reflecting tapes properties. You will also learn about the isolated danger mark, safe watermark, and special mark. The illustration of the presentation of the IALA system for region 'A' and 'B'. Along with the techniques involved in monitoring a passage will also be covered in this course. You will learn about the process of gathering information relevant to the contemplated voyage, and confirmation of preparation of materials essential for the completion of the voyage. The atlas of pilot charts, pilot charts, process of completing a detailed description of the voyage using charts will also be highlighted. You will learn about the effect of wind current. This course will help you improve your knowledge on how to draw the passage plan on the chart, and the points to be considered for passage planning. The process of the course line design and the changes or deviation in the passage plan will also be covered. This free online course will be of great interest to students, researchers, and anyone with an interest in marine navigation. So, register for this course and start your next learning journey today.
