Marine information system
First Claim
1. A marine information system comprising first and second spaced radar transceivers positioned along a dock for directing radar signals to a ship hull and receiving return signal from the ship hull, first and second spaced mooring tension sensors mounted on a dock for connecting to the ship by moorings and determining tension on the moorings, a water movement condition sensor contacting the water near the dock, a wind speed and direction sensor mounted on the dock for sensing wind direction and speed, a flowmeter mounted on the dock for sensing fluid flow between the ship and the dock, power sources connected to the transceivers and connected to the sensors and communication links connected to the transceivers and to the sensors for receiving information from the transceivers and sensors, and a complementary receiving communication link on the ship for receiving transceiver and sensor information.

Abstract
A docking information system for assistance in the docking of vessels uses sensors providing information indicative of the relationship between a ship and a reference, such as a dock, a coast line, a river bank, docks, bends and docking areas. A computer coordinates the information. A wireless transmitter associated with the computer transmits signals indicative of the information. A portable receiver and indicator carried by the captain of the vessel has a receiver for receiving the transmitted signals and an indicator screen to display the information. The remote receivers also include fixed monitors on the ship and on shore, and telephones on the ship which communicate with the computer and into the telephone link with shore-based communications.
