ASA 105 Coastal Navigation

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

We are offering this class over 3 Saturdays, including a review/exam day.  Upon successful completion, you will earn your ASA 105 certification.  Course Fee:  $275

You may take this course as an "auditor" and skip the exam if you do not need ASA certification.  ASA 105 certification is a prerequisite for ASA 106, Advanced Coastal Cruising and for ASA 107 & 117, Celestial Navigation.


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.
