Center Console Boats And More

How can I get a beached houseboat into the water without waiting for lake to rise?

The boat is 48 feet with steel pontoons. It needs to go sideways about 10 feet. Any ideas appreciated. Please no smart asses.
Thing is its really heavy and muddy my bobcat wouldn't lift it more than an inch. I was going to use mobile home rollers but couldn't get it high enough even to slide them under.
