A safety tether for providing a user with a connection to a vehicle includes a substantially rigid, elongate handle graspable by the user and a flexible line extending from one end of the handle and being attachable to a vehicle. An opposing end of the handle is free to move relative to the flexible line. The flexible line is elastically extendible from a relaxed configuration having a relaxed length to a taut configuration having a taut length, the taut length being greater than the relaxed length.

The present disclosure provides a flying water-ski device which enables a person to float in the air and fly in addition to gliding on the water in waterskiing. The flying water-ski device may be equipped with an airfoil having an outer form of a simplified triangle whose top faces toward the front. A flap section which has right and left flap axes may be placed at the back-end of said airfoil and right and left flaps, each of which can rotate around said right and left flap axes. A suspension support section may be suspended from said airfoil, and a harness section fixed to the suspension support section. A first tow rope may be coupled to the airfoil, and a second tow rope coupled to the harness section.

Disclosed herein is an aquatic towable device comprising a body, a towline connector, a rudder fin, and a steering apparatus. The towline connector is placed at one end of the body and above a waterline of the body when the device is occupied by a passenger. The rudder fin is attached pivotably to an underside of the body and placed toward the towline connector and positioned so at least part of the rudder fin will be underwater when the device is occupied by a passenger. The steering apparatus is attached to the rudder fin that pivots the rudder fin and is accessible from a top side of the body.

A tension device for securing a floating structure includes an elastic member, first and second end members, and an inelastic member. The elastic member is stretchable under tension from an unstretched length to a stretched length. The first and second end members are carried at first and second ends of the elastic member, respectively. The inelastic member is secured to the first and second end member and limits the stretched length of the elastic member.
