ASA 105 – Coastal Navigation

coastal navigation asa 105

Learn the basics of coastal navigation including piloting and navigation: chart skills, course plotting, and tides and currents.  Whether new to sailing or want to brush up on your piloting and navigation skills, this course is for you.

You will learn piloting and navigation skills in two days of classroom instruction and a review/test session.  Upon successful completion, you will earn your ASA 105 certification if you are a current ASA member.

In addition, an optional follow up day sail on the Chesapeake Bay will be offered ($50) to apply your practical navigation skills. With the completion of this day sail, you will also earn your USNSA Piloting and Navigation certification based on the Navy standards.


The course will cover navigation aids such as buoys, day-marks, and lighthouses; how to read charts; other publications; magnetic and true north direction; checking for compass deviation; how to use a hand-bearing compass and get a position fix based on charted landmarks; how to find the boat’s position on the chart using both the bearings and Lat/Long; plotting courses, deduced reckoning (“dead reckoning”); use of depth sounder and charted depth contours; reading tide and current tables; and impacts of weather, wind, and current on navigation.



The class will be based on ANSA provided materials as well as recommended readings from the following resources.   It is recommended that students use at least one of the following references or sources to help prepare for the course.
