This course covers all aspects of Navigation Rules, starting from the basics and ending with all you need to navigate safely according to the Rules. It is for power and sail vessels, large and small, recreational or professional. The Rules are the same for "...every description of water craft used as a means of transportation on water."
How the course works
Please read the general description of How the Courses work. Those notes apply to all courses. You can sign up for a course anytime the enrollment is open. If the course has already begun, you can still join, but will need to submit the quizzes sequentially.
There are no prerequisites for the Nav Rules Course. There are a few instances where knowledge of specific navigation techniques is presumed, but these will be referenced and explained as they arise. Those planning to use radar on their vessel, will find that our Radar Course is extremely valuable in applying the rules that relate to radar usage, but this is not a prerequisite for this course.

- Know and understand the basic definitions the rules are based upon
- Understand the role and functions of a "proper watch"
- Know who has the "right of way" in an encounter with another vessel and how this might depend upon where you are at the time
- Know what to do when you have right of way and what to do when you don't
