Nautical charts depict the configuration of the shoreline and seafloor. They provide water depths, locations of marine obstructions, aids to navigation, and other features.

Many mariners carry on the traditions associated with navigation by plotting a position and a course on a paper nautical chart. They accomplish this task using traditional marine navigation tools, including: compasses, chart dividers, rulers, protractors, sextants, chart plotters, binoculars, chronometers, star finders, and more. It is good seamanship for mariners to know how to use these nautical tools work and to pass on that information to the next generation. High-quality modern nautical tools also make great gifts for anyone with a love of maritime history.

Choose from a worldwide selection of country flags, pennant flags, numerical flags, and signal flags needed for flag state compliance for vessels sailing. These flags are used to identify the flag state a vessel is sailing under and to communicate with other vessels under the provisions of the International Code of Signals.
