A nautical chart is the primary tool used to plot a course and navigate safely on the water.
Bearing refers to the direction from the vessel to another point, usually expressed in degrees.
A marine compass is used to determine and maintain the vessel's heading.
A waypoint is a predetermined location or point along a navigational route used to help guide the vessel.
A fathometer, also known as a depth finder, measures the depth of the water beneath the vessel.
A green can-shaped buoy indicates the port side of the channel when returning from sea (Red Right Returning).
A red and white vertically striped buoy indicates safe water all around it.

To convert from magnetic north to true north, you add the local magnetic variation (also called declination).
If unsure of your position, stop the vessel and take bearings from known objects to re-establish your location.
A radar reflector increases the visibility of a small vessel on other vessels' radar screens, improving safety.
The first step in plotting a course is to accurately determine the vessel’s current position on the nautical chart.
