I've never read the process ... but I've done it with a 19 footer and
smaller many times.

1. get a lot of jackstands.

Me too. Then I;

2. Back the boat up to something stout... like a large oak tree.

3. Tie lines from the lifting rings to the oak tree.

4. Drive/pull the trailer out from under the boat while at the same
time, sticking jack stands underneath as you go (tell the driver to
drive slowly LoL!) Helps to have the forward set of stands not to far
forward (you'll see why when you're putting it back on the trailer)

To get it back on, you don't need the tow vehicle. Use the trailer's
winch to pull itself back under, removing the stands as you go (don't
forget to keep the boat tied to the oak tree).

It's no trouble at all with a "winch on" type trailer. I've never
tried it with a "float on" type though, there might be a problem
there. Obviously you have to go slowly and carefully (helps to have
good accidental health insurance).
Try it with a small boat first, maybe a skiff. A larger boat works the
same way, it's just not as forgiving of error.
