ABSTRACT:
A towing system, especially useful in wake boarding is described. Using a beam mounted to a tower and a carriage that travels over the beam, a towline attached to the carriage of one variation of the system offers a rider more air time and eliminates certain burdens created with the towline/rope. Further, more room to gain speed and set up for the wake jump, more air and natural feeling during the air time due to the elimination of rope tightening otherwise experienced. A number of other possible system variations and options in addition to the basic beam and carriage configuration are also disclosed. Preferably, the beam and carriage are configured to offer a virtual pivot point for the tow rope that is pushed forward of where the beam is mounted.
