Dragging this thread up again, as I am getting set to build myself a "perfect pull" substitute. I am looking for the dimensions of the device that used to be sold, made out of metal with long legs that went out on the dock at an angle, with a metal plate angled like a slalom ski on edge to stand against, and the handle going over a rubber "pulley" sort of thing down to be secured at the base. The handle line folded over the pulley pretty low.
At one point, I had a line on a used one, but shipping made it prohibitive to obtain. So, will build my own out of wood, secured against posts supporting my carport, once I can figure out the correct edge angle, anchor point for the line, distance between edge of the "ski" and the actual handle, and height at which point the line will go out to the handle. I will try to figure out a way to mimic the rubber pulley to give it some give. EDIT: After reading through the rest of the thread, I am going to see if I can figure out a way to make the angle "across the wake" in relation to the pull of line adjustable so it is not 90 degrees across as was the case with the Perfect Pull. My goal in doing this is to make something where I can experiment with and find a taller, more leg extended lean (not pull) away from the boat, with my balance stacked better over my feet. I do not plan on spending hours on it statically, but just as an aid in finding some physical feedback in my feet and body so I can then take that out on the water and do some whip drills and other things to work on it out there. Getting a better posture without separation between hips and handle, and more efficient lean using that better posture, is my primary goal this year.. Though I will not achieve this goal fully on dry land, I think for a guy with limited water time, it at least can be a tool on the path.
If anyone has a Perfect Pull and can give me some measurements, let me know. It is a starting point.
