TIDAL CURRENT INFORMATION DISPLAY DEVICE

A tidal current information display device (1) for a movable body (11) includes a position measurement module (151) to detect a position of the movable body (11), a geographical information selection module (152) to determine geographic information to be displayed on a display screen (16) based on the detected position, a tidal current information receiving module (153) to receive and store tidal current information based on the detected position, a tidal current information display module (154) to generate display data for displaying a first graphical user interface (GUI) (202) for displaying the tidal current information corresponding to a predetermined position on the geographic information displayed on the display screen (16), and a voyage time calculation module (155) to calculate an estimated time for the movable body (11) to reach the predetermined position. The first GUI (202) is configured for showing at least one of: the estimated time and a direction and speed of a tidal current at the estimated time.
