Abstract: A water skier tow bar assembly includes a tow bar handle and control actuators that can be actuated by a user and indicative of a desired skier condition. A housing is connected to the tow bar and includes a wireless radio transmitter operatively connected to the control actuators for generating wireless radio signals of desired skier conditions or generating wireless radio signals indicative of a skier down condition. In one aspect of the invention, a wireless radio transmitter is contained in a housing formed as a float assembly and has an aperture through which a tow rope passes to permit the housing to be carried by a tow rope. When a skier falls, a water actuated switch initiates transmission of a wireless radio signal indicative of a skier down condition.

Abstract: A water skier tow bar and float assembly includes a tow bar handle, control buttons on the tow bar handle and a float assembly connected to the tow bar handle. A wireless radio transmitter is mounted within the float assembly for generating wireless signals indicative of desired water skier conditions based on water skier actuation of the control buttons.

Abstract: A water skier alert system is used with a boat towing a water skier via a rope and tow bar handle secured thereto. A radio receiver is adapted to be positioned on the boat towing the water skier for receiving wireless radio signals transmitted from the tow bar handle in response to a skier down condition or water skier actuation of a desired water skier condition. A display is operative with the receiver and has indicia on the display that are actuated by the wireless transmitter signals and indicative of the skier down condition and each of desired water skier conditions. The tow bar handle includes at least one battery and a pressure sensor positioned at the grip portion and sensitive to hand and/or finger pressure exerted by a water skier. Control actuators are positioned along the grip portion and indicate a desired water skier condition.

Abstract: A marine instrument includes a housing, a processor for processing an input signal comprising vessel navigation information, a substantially water resistant display connected to the processor, the display having at least one control switch extending outwardly from the display, a removable face plate having a window, a front surface, and a back surface, the removable face plate having at least one substantially flexible raised portion along the front surface forming a complementary concavity along the back surface, the face plate positioned on the display so that the concavity matingly receives therein the control switch, and so that the display is visible through the window, and a bezel connected to the housing so as to hold the removable face plate in place.
