This standard requires purchasing a large manual at a cost of $60-$70 from ASA. We highly reccomend you go through the entire manual before you arrive to sail.

- Explain chart symbols and conventions on U.S. nautical charts in accordance with international terminology
- Identify a source of official U.S. Coast Guard navigation publications
- List the publications and instruments required for prudent navigation in the local area including ASA minimum requirements
- Use the tide and current tables to find times/heights of tides and direction/rate of current at reference and secondary ports
- Convert courses and bearings between true, magnetic and compass
- Check compass deviation by means such as a transit bearing
- Plot a dead reckoning position on a chart using speed, time and course to steer
- Allow for the effect of current and leeway to plot the estimated position
- Determine a course to steer which takes into account known current and leeway
- Determine current given the course steered and speed and two observed positions.
- Plot a chart position from terrestrial objects using various types of bearings, transit range and distance off the object
- Use the above techniques to chart a course of at least 20 miles and 3 course changes.
- Explain the terms and characteristics used for lighted navigation aids
