Welcome to the turtle club. That stunt doesn't happen often because to do it usually requires one to be in heavy winds that make sane Hobie sailors get off the water.
Go
here for righting instructions.
Congratulations on correctly figuring out how to bring the boat from a turtle to a capsize position. There are different systems to right your boat, but they all have one thing in common - from a capsize, the righting line goes over the hull in the air. I suppose you were able to right the boat from a capsize without throwing the line over the hull in the air because of strong winds combined with enough weight and good technique.
Turtling the boat is usually caused from high winds pushing on the tramp or a leaky mast (or someone staying on the sail and their weight pushing the mast down). Since you were able to get the boat to a capsize position I suppose your mast is properly sealed, so it must have been high winds that turtled the boat. High winds and good technique lessen the need for weight in righting - in 30 mph winds I was able to completely right my turtled 18 solo, and I weigh 220.
