Abstract
Abstract A ski tow arrangement having a start up section wherein a skier is gradually brought up to the speed of the tow. The start up section generally comprises a roller bearing section above which extend a pair of moving handrails. By gripping the moving handrails while standing on the roller bearing section a skier is brought up to the speed of the tow. The roller bearing section is adjacent a conveyor belt type tow. The conveyor belt tow and the moving handrail move at approximately the same speed. A second roller bearing section is positioned adjacent to the opposite end of the conveyor belt tow to aid in the exiting of a skier from the tow. The tow can be covered by a hood to protect the tow and skier from the weather.
