Different types of marine trackers include cruise ship trackers, tall ships trackers, Great Lakes shipping trackers, oceanographic research vessel trackers and worldwide ship traffic trackers. The trackers provide location data for various types of sailing vessels that can be viewed online at SailWX.info. The site features an interactive map that indicates the exact location for various types of vessels based on reports transmitted by the trackers. It also lets users search for individual vessels by name.
Marine trackers use global positioning satellites to determine the locations of various types of vessels and to report the location of tracked vessels at regular intervals. The cruise ship tracker provides an interactive map along with a list of the names of more than 100 cruise ships, along with the exact latitude and longitude of each ship. The tracker also reports the date and exact time of the report according to Greenwich Mean Time and the radio call signal of each ship.
The tall ships tracker tracks the location of vessels designated as tall ships by the Sail Training International organization. These vessels, which are located in ports around the world, gather annually for races, regattas and other events held in various locations periodically. The Great Lakes Shipping tracker provides similar information for cargo ships scattered throughout the Great Lakes, Saint Lawrence River and the Gulf of Maine.
