Coastal Navigation Standard
OBJECTIVES
To be able to demonstrate the navigational theory required to safely navigate a sailing cruiser in coastal or inland waters. The concepts are practically introduced in the Intermediate standard and practically tested in the Advanced standard. The standard is recommended to be completed prior to the Intermediate standard.
PREREQUISITES
None.
This is one of the standards required by CYA as a prerequisite to taking the Advanced Cruising Standard. You can attain this standard by passing the CYA Coastal Navigation Examination.

1. Course: The direction in which a vessel is steered or is intended to be steered (direction through the water).
2. Course to steer: Course to steer to counteract current and leeway
3. Heading (HDG): The direction in which the boat is pointing in any instant.
4. Course To Make Good (CTMG): The course for planning purposes that indicates the intended track from departure to destination.
5. Course Made Good (CMG): The single resultant direction from the point of departure to the point of arrival at any given time.
6. Speed (S): The speed of the boat through the water.
7. Speed Made Good (SMG): The speed of the boat achieved over the CMG line.
8. Set (Set): The direction in which the current is flowing.
9. Drift (DFT): The speed (in knots) of the current.
10. Total Drift: Distance between the DR position and Fix for the same time.
