Update Du Jour . . .
I'm into Day 2 taking the rear seat assembly out. IT weighs a lot . . . I'm guessing 500 lbs. Anyway, it is hinged at the rear with 2 hidden hinges. 4 bolts per hinge on the engine side, and I assume the same internal to the swim deck. The bolts are about 1-1/4", so to clear the bolts the seat assembly has to move forward. The only problem is that there in not clearance at the rear or the front to clear the seat assembly from the bolts. The best I can figure is that the front of the seat assembly would have to be raised up to a point where it can clear the obstructions. Not sure if the is 45˚ or more like 60˚.
So, I was planning to lift the thing more level than tilted. . . . got to re-think things.

Front edge of seat assembly, the wetbar prevents forward movement.

My 'tip of the hat and a hearty handshake' to anyone with some ideas on how to get this thing free of the hinge bolts. I do plan to cut the bolts down upon re-installation so things won't be as difficult.
In other news, I finished the hardwood floor that I've been working on for the past month. So, the Honey-Do list is pretty short now. The boat is becoming Job 1.
