Chartwork for Oceangoing Navigation

Maritime Chartwork

Lesson Objectives

Develop Advanced Chartwork Competence: Train learners to accurately plot positions, bearings, courses, and tidal calculations on nautical charts, with increasing complexity from coastal navigation (24 NM) to extended ocean passages.

Develop Advanced Chartwork Competence: Train learners to accurately plot positions, bearings, courses, and tidal calculations on nautical charts, with increasing complexity from coastal navigation (24 NM) to extended ocean passages.

Apply International Standards for Safe Navigation Ensure learners can integrate chartwork with COLREGS, international conventions, and seamanship principles, enabling them to confidently navigate vessels beyond 24 NM into open sea and oceangoing routes.

  • How to plan a voyage at sea
  • How to apply the International Regulations for the Prevention of Collisions at Sea (IRPCS) to ensure timely actions are taken to avoid collisions
  • How to use the radar for collision avoidance manoeuvres
  • How to become proficient in using navigational charts, GPS, magnetic compass, radar, and echo sounder.
  • How to speak with confidence on a VHF marine radio.
  • How to interpret meteorological data
  • How to use the principle of ‘’Plane Sailing’’ to avoid total reliance on navigational aids in determining your position at sea
  • How to contribute in Search and Rescue operations
  • How to build confidence as a Sea Captain.

You will be taught plotting positions on charts, drawing True courses, plotting fixes, and conversion of Compass courses/bearings into True courses/bearings by using CADET RULE.

Charts, parallel rulers, dividers, pencils, and soft erasers shall be provided.

You will also be required to do Revision work on your own based on THE SKIPPER’S COMPANION by Captain O.Kishun. The instructors will assist you if you have difficulty answering the Multiple-Choice Questions in the book.

Demonstrate advanced chartwork competence by accurately plotting positions, bearings, courses, and tidal calculations for both coastal (24 NM) and oceangoing navigation.

Have the ability to apply COLREGS in simulated and theoretical navigation scenarios, demonstrating knowledge of collision-avoidance rules. Integrate chartwork practices such as SOLAS requirements for safety of life at sea.

Prepare and execute safe passage plans that integrate tidal streams, variation and deviation, meteorology, and hazard awareness, enabling informed navigational decision-making in both coastal and open-sea contexts

calculation of the height of tides, calculation of sunrise/sunset times

Safety and security on ocean passages. Anchoring of vessels.

Use of radar to determine the true course and speed of a contact, its Closest Point of Approach (CPA), and anti-collision manoeuvres.

Determination of courses to steer and distances to run without the use of charts (Plane Sailing)

Stationary, you might need

Charts, parallel rulers, dividers, pencils, and soft erasers.

Please note that while our theory lessons are designed to provide comprehensive guidance. Participation in these courses does not guarantee passing a skipper certification test or achieving a specific level of skill. The success of each participant depends on their effort, learning pace, and ability to apply the skills taught during the lessons.

Our instructors will do their utmost to ensure a safe and educational experience. However, boating inherently involves risks, and participants are expected to follow all safety instructions and guidelines provided during the lessons.

We encourage all participants to ask questions and approach the learning process with an open mind and a commitment to safety. For more information about our lesson plans, pre-register by contacting us.
