摘要:
For use with towable airfoils used to supply lift to a towed rider to assist with jumping in sports and recreation, a handle system having one or more control lines for coupling to the airfoil, and a line for coupling the handle to a tow vehicle, the one or more control lines and line for coupling to the tow vehicle being coupled together by a tension translation mechanism that divides the tension from the line for the tow vehicle to the one or more control lines by a predetermined factor, which typically would be other than 1:1. The handle system may further include an engagement mechanism for engaging the one or more control lines to lock or brake a line.
