Abstract: A microprocessor controlled device and method utilizing an information database concerning harbor attributes and a collection of harbor maps and images, together with algorithms that determine which harbors are appropriate for shelter against certain weather conditions to guide a specific yacht to an appropriate harbor in various weather conditions; or other relevant harbor location issues that may concern a mariner. It integrates with GPS technology to determine the location of the vessel. The invention provides a convenient graphical interface allowing the user at each stage a dialog to reset the various parameters and a graphical, and narrative presentation of the various features of the selected harbors, filtered specifically to the weather conditions, the vessel perimeters, the harbor attributes and the needs and interests of a particular vessel and it's mariner.
