Abstract:
1. A device comprising: a pivot coupled to a water craft; a lever arm pivotally coupled to the pivot at one end; a tow spool coupled to the lever arm at an end opposite the pivot, the tow spool configured to provide an attachment for a towline; and a pneumatic shock absorber coupled to the water craft at one end and coupled to the lever arm at the opposing end, the pneumatic shock absorber adapted to store energy as a towing drag force is applied to the tow spool to cause the lever arm to move from a first position to a second position and to provide a restoring force to cause the lever arm to move from the second position to the first position as the towing drag force is reduced, the restoring force being pneumatically adjustable by a pressurized air line.
