Coastal Navigation (ASA 105)
This course is designed to help you navigate within sight of land in coastal waters. This is one of the most important courses you can take. If it takes an additional 10 minutes to get from point A to point B, nobody cares, hit a rock - everyone is going to get excited.
The course is taught in two ways, 1) using traditional instrumentation, but not GPS and 2) as if you have lost all electricity on the boat, so there is no GPS and for that matter no knotmeter, no depthsounder - only a compass! We even teach how to create an emergency sun compass!!
Topics covered are:
- Definitions of navigational terms (Domestic & International).
- Pro and Cons of different types of necessary navigation equipment.
- Symbols, abbreviations and conventions for U.S. Hydrographic Charts.
- Symbols, abbreviations and conventions for International Hydrographic Charts - they are different.
- What to look for (navigation wise) when approaching a foreign harbor.
- Usage of all the government publications - light list, coastal pilot.
- Applicable Rules of the Road, both U.S. and foreign.
- Thorough coverage of the use of Tide and Current Tables.
- Understanding of compass errors.

- Plotting a dead reckoning position.
- How to use a danger bearing.
- Quick calculations for Speed Of Boat (no knotmeter) and distance away from a light.
