A temporarily mounted towing device for towing a water sporter as part of a water sporting activity. An elongate towing member is stowed within a storage housing temporarily secured to the bottom of a watercraft. The storage housing extends upwardly from the bottom of the boat in a nominally vertical direction. The towing member remains in a vertical orientation to operate as a pylon towing device. To stabilize the pylon, front and rear nylon tie downs or similar removable bracing devices are used on both sides of the towing vehicle.
