A leash and information system assembly includes a flexible strap, a flexible tether cord, a data processing module, and a display module. The flexible strap and the flexible tether cord connect a water sports vehicle to a user of the water sports vehicle. The flexible tether cord is connected to the flexible strap and the second end is configured and dimensioned to connect to the water sports vehicle. The tether cord width is substantially less than the strap width and the tether cord length is substantially greater than the strap length. The data processing module is mounted within a water-proof enclosure and positioned along one of the flexible strap, the flexible tether cord, and the water sports vehicle. The data processing module is configured with logic to receive, parse, process, and output data generated by a source external to the data processor. The display module is mounted within a water-proof enclosure and positioned along the flexible strap and in electrical communication with the data processing module. The display module includes a plurality of display symbols representing at least one of time, atmospheric weather conditions, water conditions, and global positioning. The display module is configured with logic to receive, process data communicated from the data processing module to convey the data to the user by activating at least one of the display symbols.
