New subfloor in older houseboat

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.
