Abstract: A motorboat is controlled by a following water skier, when he or she is solo waterskiing, without the assistance of any driver. Optionally, a driver may operate the motorboat while towing a water skier, and an observing passenger is viewing the water skier. Optionally, a driver may operate the motorboat, with or without a passenger, and not towing a water skier. Motorboat operational controls, located both at the control center of the motorboat and on the skier's tow handle include: start and stop the motor; increase or decrease of throttle settings; select cruise speeds; turn left or right; actuate horn; automatic switches to stop engine when water skier removes his or her hands from tow rope handle and/or falls. The control signals are transmitted via electronic circuit wires extending throughout the center of a tow rope assembly and beyond. Optionally, control signals are transmitted by ultra high frequencies and related signal equipment.
