Abstract: The invention includes a marine telematics system comprising a satcom unit on a boat, a user interface for the satcom unit, a web-based user interface for the telematics system, and a land-based center of operations. The land-based center of operations receives signals from the satcom unit on the boat about the location of the boat and sensor responses to detectable events. The marine telematics system is customizable through a web-based interface, allowing boat owners to provide information and instructions to the land-based center of operations for handling particular situations that may arise while the boat is in use or at dock. The web-based interface further allows boat owners to plan voyages by setting series of waypoints, and the land-based center of operations may assist the boat owners by providing feedback during their voyages based on the waypoint information previously provided by the boat owners.
