How to Use a Chart
Charts provide information essential to your safety afloat.
Even with GPS and electronic navigation, the chart is needed to tell you
what is around you and between you and your intended destination. A system
of symbols is used by cartographers to tell you what lies below the surface
of the water and the depths of water. There is key information about visible
landmarks and navigation aids to help you navigate your course. The chart
also is your link with the GPS via its grid scale, compass rose, and distance
scales. A brief introduction to latitude and longitude provides insight
to the operation of GPS receivers.
The NOAA Chart No. 1 is the quintessential reference to
chart details, but is very difficult to understand. This seminar walks
you through what you really need to know in an entertaining and interesting
fashion, and provides you with a Maptech Waterproof flip-fold waterproof Chart
Symbols and On-the-Water Guide to take along on the boat with you.
In addition to showing you all about your chart, this seminar walks you
through the essentials of laying out a safe course, and the steps to measure a
course with the USPS plotter.
