Abstract

An retractable tether device is used to alert the driver of a fallen athlete and to return the athlete, primarily a wake surfer, back to position behind the watercraft. The tether consists of a coil spring with a storage reel for the line and an audible alert notification. When a wake surfer falls off the surfboard, the tether will pull out from the device. Simultaneously, the boat stops and the coil spring will retract the tether to reposition the wake surfer behind the boat. As the tether is reeled out, an alert such as an audible noise and/or vibratory signal will cue the driver that the wake surfer has fallen. To further ensure safety, each end of the apparatus would have break away clips. The safety break away clips would release in the case where the driver did not stop the boat. The tether could be connected to the tower, pylon or back of the boat'"'"'s towable hook. As a result of this device, the surfer can efficiently engage in an increased number of wake surfing sessions.

Claims

1. A wake surfing tether system attached to a boat comprising:

a. a rotational device attached to the boat, the rotational device having a power spring;

b. a tether attached at a first end to the rotational device with a first breakaway clip;

c. a second breakaway clip attached to a second end of the tether and configured for attachment to a user;

d. a damper attached to the power spring, the power spring being configured to hold the tether with slight tension when attached to the user while in a surfing position and the damper controlling a speed at which the tether is returned;

wherein when tension of the tether is increased due the user falling into the water from the surfing position, a resistance is created causing the tether to pull out of the rotational device until the boat comes to a stop or one of the first or second breakaway clips breaks away or the resistance applied to the tether due to the fallen user is otherwise lowered;

once the resistance is lowered, the power spring pulls the tether and reels the tether in to the boat.

2. The system of claim 1 further comprising an audible alert device attached to the rotational device, wherein the audible alert device is activated by reeling out of the tether.

3. The system of claim 1 further comprising a vibration alert device attached to the rotational device, wherein the vibration device is activated by reeling out of the tether.

4. The system of claim 1 further comprising a wireless device attached to the rotational device and an alert device visible by a driver of the boat, the wireless device being configured to actuate the alert device based on reeling out of the tether.

5. The system of claim 1 further comprising an actuator device in communication with an engine control module of the boat and configured to reduce an engine speed based on reeling out of the tether.

6. The system of claim 5, wherein the actuator device reduced the engine speed to an idle speed based on reeling out of the tether.

7. The system of claim 1 further comprising an actuator device in communication with a transmission control device and configured to disengage a transmission of the boat based on reeling out of the tether.

8. The system of claim 1 further comprising an actuator device in communication with an engine control device and a transmission control device, wherein the actuator device is configured to reduce an engine speed and to disengage a transmission of the boat based on reeling out of the tether.
