Beached Boat, Need idea
Sorry to hear about your misfortune, which I''m certain has been a common event along the Atlantic & Gulf waters this season. The obvious method of course, is to hire a mobile crane with a long enough reach to lift the boat up with straps & extend out to water, deep enough to float it.
You may risk damaging the hull by other methods, such as sliding back to the harbor. This can be done by jacking up the boat enough to secure lateral planks to the hull side resting on the beach. Then slide the boat down the beach on greased timber tracks with the assistance of a cable secured to either a powerboat, or tow-truck onshore. The truck cable of course, needs to transverse the water by being routed through a block secured to a distant fixed object. The geometry may or may not work, depending upon the shoreline contour.
Perhaps a line brought ashore from a secure anchor, set to the bottom with your dinghy, can be used with either your boats'' windlass or a vehicle mounted winch. Wait for a moontide to reduce the travel distance.
Good luck in whatever method you decide upon and keep us posted with the results of your efforts.
