Navigation

Navigation, along with piloting, is the science of safely moving a boat from one place to another. Safe navigation includes marine chart reading, course plotting, and position finding underway. It takes into account tides and currents, an understanding of the maritime Rules of the Road, and correct interpretation of weather data. Understanding the capabilities of a specific boat in a variety of wind and sea state conditions is a vital part of safe navigation and piloting.

Integrating Radar with Computer Charting

Fog can be quite common in the summer here in the Puget Sound, often in thick patches in the channels between the many islands through which we cruise. And the fog can be quite dense, although often the layer is only 20 feet thick. It’s…
