Yes, the "ledge" the motor is sitting on is the motor bracket (it connects the motor to the transom of the boat). My harness is exactly 12 feet from connection to connection and just barely clears the motor (which I think is better than having extra room to get hung up on stuff). And it is Airhead. I believe that our boats share hulls and brackets, or ledges, so our dimensions should be the same. Hope that helps.
