Narrative:

During the takeoff run of about 1000 ft or more, the aircraft started to lift off. The aircraft would not climb out of ground effect. Realizing I would probably stall way beyond the airport, I let the aircraft go into the soft marsh off the end of the runway. There was no wind at the time of takeoff roll. I think a tailwind developed just at liftoff.
