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.
The time needed to make a new nautical chart depends on how many pieces of the puzzle are in the box.
