I don't see how it would be possible. A 21' boat like that upside weighs
more than the strength of four guys NOT standing on solid ground to turn
it over. How could you get leverage?

Hanging on ropes over the hull tied to the opposite gunnel, with feet
braced against the bottom. Get it rocking until you can pull it over.
Probably impossible with this type boat, but sailboaters do it.
Of course they have a centerboard to stand on, but also a mast working
against them.
I googled a bit about it, and the best I could find was a guy who had
singlehandedly righted his 13' Boston Whaler when it turned turtle.
No mention of what motor was hanging on it.
Coast Guard has a procedure with a bridle tied to the off gunnel and
then pull under power. Boat "naturally" rights.
What made me think about it was the amount of boat shown above water
in the Coast Guard video. Looked like maybe 10% of the boat.
For that boat maybe 400 lbs.
So it might seem you only need that much force to right, since the
boat was almost neutrally buoyant.
On reflection though, as the opposite side rises from the water and
sheds it, it will increase the weight that has to be overcome.
Like I said elsewhere, it was just a thought.
Mostly because there were 4 exceptionally strong and heavy guys.
