Coastal Navigation Standard (105)
General Description: Able to demonstrate the navigational theoryrequired
to safely navigate a sailing vessel in coastal or inland waters. There
is no Sailing Skills part to this Standard and practical application of
this Sailing Knowledge is found in the Advanced Coastal Cruising
A Certified Sailor has successfully demonstrated his or her ability to:
- Explain the chart symbols and conventions on U.S. nautical charts in accordance with the terminology of chart #1.
- Identify a source of official U.S. Coast Guard navigation publications.
- List the publications required for prudent navigation in the local area including the following ASA minimum requirements:
- Large scale charts of the area and chart #1
- Federal Requirements for Recreational Boats
- USCG Navigation Rules
- State small vessel regulations
- Local rules and regulations, if applicable
- Local sailing directions
- Tide and current tables, if applicable
- List of lights, buoys, and fog signals
- Radio aids to navigation (if using radio or RDF)
- List the instruments required for prudent navigation in the local area including the following minimum requirements:
- Steering compass and deviation table
- Handbearing compass and / or pelorus
- Protractor or parallel rule
- Depth sounder or leadline
- Pencil, eraser, and notebook
- Watch or clock
- Log / Knotmeter
- Describe the purpose of "Notice to Mariners."
- Use the tide and current tables to find:
- Times and heights of tides at reference and secondary ports.
- Direction and rate of current at referenced and secondary stations.
- 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:
- Two or more bearings on different objects taken at one time.
- Bearings at different times (i.e. a running fix).
- One bearing and transit range.
- One distance (i.e. a sounding or dipping a light) and one bearing.
- 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.
- Explain the significance of shapes, colors, and lights used in the buoyage system.
