[Finster]

I am not sure of the buoyancy of the single for the 20, but I would think it be in the neighborhood of 350lbs +- at the water line, at a guess. At that the weight of a 200 would be fine.
I understand well what Dunk is saying, it's like haveing a 3.4 liter merc, weighing 575lbs sitting on a Gill bracket with no floatation....Not recommended! Though the boat didn't sit as low in the stern as thought.
I know the Don's brackets have 800lbs of buoyancy for a twin, 500 for a single for the 23's and as I said I am just guessing at the 20. But even if it was 250lbs buoyancy it would still work fine.
How's that for a fine Finster editorial!
