1. In a programmable microprocessor based tidal information calculating the displaying device, having memory for storing program code and tidal information input means for entering data and selecting functions, and display means for displaying at least port and tidal information, a custom port tide prediction method comprising the steps of:

  • pre-storing in the memory a data base of known tide data for a plurality of ports, at least one of which ports is adjacent to a desired port;

    inputting with the input means observed or measured tide offset data for a desired port, the offset data being relative to said at least one adjacent port of said plurality of stored ports, said offset data being at least one of a time of a high tide at said desired port relative to said adjacent port, a time of a low tide at said desired port relative to said adjacent port, a height of a high tide at said desired port relative to said adjacent port and a height of a low tide at said desired port relative to said adjacent port;

    producing with the microprocessor and storing in the memory, custom port data for said desired port as a combination of said tide offset data for said desired port and the tide data associated with said at least one adjacent port; and

    producing with the microprocessor using said custom port data stored in the memory and displaying on the display means, tidal information for the desired port, in response to inputting with the input means a request for tidal information for the desired port.
