Without tearing up the exisiting subfloor, which is structurally sound, how can I level the sagging which has taken place between the supports? The supports are about 3 ft apart and span approx. 10-12 ft. The sag is about 3/4" deep and inconsistant between each set of supports.

The house boat is over 35 years old.

You'll have to take up the support to increase the support beneath it.

support. Can you jack up off the hull??? below?? If glass 2X4 on edge under it and long screws down into them???
