Basic Navigational Concepts

Coordinates and Bearings

Understanding latitude and longitude is critical for effective navigation. These coordinates create a grid system covering the earth, helping you pinpoint your location.

• Latitude: Measures how far north or south you are from the equator (ranging from 0º to 90º).
• Longitude: Measures how far east or west you are from the Prime Meridian (ranging from 0º to 180º).

Bearings indicate the direction you should steer your vessel. Expressed in degrees, they help you maintain your course relative to true north. Use terms like “true bearing” (referring to the earth’s poles) and “magnetic bearing” (based on magnetic compass orientation).

Triangulation: Locating Your Position

To locate your position using traditional methods, follow these steps:

1. Identify Landmarks: Look for three identifiable landmarks that are marked on your charts and are easily visible.
2. Take Bearings: Using your compass, measure the bearings to these landmarks, noting each direction in degrees.
3. Plot Lines on the Chart: Use parallel rules to draw lines from the bearings on your nautical chart. Where these lines intersect will indicate your location.

This process of triangulation ensures that you know exactly where you are on the water, a crucial aspect of safe navigation.

Navigating to Your Destination
