That might work, I would imagine that the secret to this device working is the leverage and length of the pole. I'd also take steps to make the pole so that you can walk out on it as well as modify the end of it so that it doesn't chew the heck out of your boat, which is why I'm sure people used the lexicon rather than sheet metal.
Good luck,

Right, exactly. It was just something I came across today. For what it's worth, I'm seriously considering using a 7' length of 2x2 x1/4 wall" aluminum square tubing for the pole (with non-skid glued on) and having an iron worker weld on maybe a 6" "T" lengh of the same material at the bottom to bare the righting weight against the hull. This stuff is light and strong.

Once the pole part is built I would use a stainless steel hinge to connect a fold-able dagger well insert to the "T". This "T" is what really bares all of the weight, and you want it wide enough to eliminate any side to side movement. Glue some neoprene padding on the bottom of the "T" section where it contacts the hull. A hole for the cross beam line could be drilled through the upper end of pole and you could epoxy in nylon bushings like you have on the rudder assembly to keep the line from fraying on the bare aluminum holes. The question is would I need 1/4" wall aluminum for the pole or would 1/8" be enough to support a 220# man? This is the direction I'm currently going in. The end that rests on the boat (once welded) would look something like this, only solid boxed in all the way around. Dagger insert Hinge would be screwed into the bottom...
