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:  TBD

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.

TOPICS:

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.

PREREQUISITES:

§  The desire to learn navigation and apply the skills in a classroom setting, no other ASA certifications are required

    We will use a combination of Zooms and three Saturdays at the beautiful West River Sailing Club, starting with beginning basics on Day 1 and advancing to more complex plotting and calculations on Day 2.

    Zoom 1 - Jan 11 - Intro, Q&A, schedule, resources

    Day 1 - Jan 21 - Basic concepts, definitions, plotting skills & math

    Day 2 - Jan 28 - Advanced plotting, problem solving, set and drift, danger bearings, running fix

    Zoom 2 - Feb 1 - Q&A, review

    Day 3 - Feb 11 - morning review and practice, afternoon exam

    Day 1 and 2 are optional for experienced navigators, although strongly recommended.  If you cannot make one of the Saturdays, let us know as we have several people already who need a different day and we can add a day or some Zoom's to help cover the topics.

    There are many resources available for studying and practicing marine navigation and in addition some sailors may already have a good knowledge base.  

    Following registration, ANSA will provide our training materials that provide a complete tutorial and guide to all of the navigation skills and requirements, including previous class videos.  However, students are also advised to utilize at least one other reference source as well as additional practice problems to fully prepare for the exam.

    The fee for this class is $275.  In addition students must have a current ANSA membership ($55 - $75), renewed as of Jan 1, 2023. Become a member.

    Depending on the number of students who enroll, we may add sessions to accommodate everyone and provide more flexibility in scheduling.
