A steel cable and winch might do it...
Most rope has an elastic/stretch nature to it. The longer the rope the more stretch.
Once the stretch is taken up , you're committed to the force being applied. Releasing tension means something has to give. In my case , the boat rocks. Though tension controls the amount.
I've had a boat gunnel pulled to the waterline almost in shallow water (a dozen feet maybe) pulling on too much weight....Felt like a large engine block kind of weight. It held fast. And likely remains there....
