Well Mary, I never tried this firsthand, but was out overnight once (solo, turtled and dismasted), and as soon as the mast came free, I gave up trying. I've told lots of people that story over the years, and several have told me that it's far EASIER to right a boat from turtle without a mast (less resistance from the sails, etc.).

I would think that the procedure is the same as righting a cat in general, especially with a power boat. With the mast missing, one would tie onto the dolphin striker (yes, this will probably bend it depending how it is tied, but that's a problem to be dealt with after you get the mess back to shore).

And to clarify a few comments about righting with a power boat, the best procedure that I have seen is as follows. Get the capsized boat perpendicular to the wind. Tie one end of the tow line to the mast base / dolphin striker, run it out under the deck of the windward hull (which is under water), run it across the bottom of the turtled boat to the power boat (which is setting up on the downwind side of the capsized boat). On the power boat, run the line around a cleat 1/2 TURN, and have the power boat crew HOLD the tow line, but DON'T TIE OFF. The idea here is, you want the cleat to help the crew hold the line so they aren't pulled overboard, but they need to be able to release it instantly. Have the capsized boat's crew sit or stand on the leeward hull, holding the righting line.

The power boat slowly goes down wind to get the slack out of the line. When the slack is out, everyone needs to brace for action. Apply power directly downwind to pull on the line while the crew is pushing the leeward hull down with their weight. As soon as the boat starts coming over (the windward hull is vertical and coming downwind), the power boat crew releases the tow line, and the capsized boat is now righted.

Obviously, it is essential that the tow line be free of knots, shackles, caribiners, thimbles, etc. so it doesn't get hung up when it needs to be released. If the line isn't released, the boat will re-capsize downwind because you can't relieve the power fast enough with just the engine, especially if the waves aren't working in your favor (been there, done that).

Hope this helps, it sounds more complicated than it really is.
