Buddy of mine is a salvor. He got called to free a 48 footer stuck on a shoal a few years ago. He showed up at high tide with all his air lift bags and gear. He got on the boat, put the boat in full reverse, hit the bow thruster alternating port and starboard. After a couple minutes of wiggling the bow back and forth, the boat backed off the shoal. Never used the salvage equipment.
Similar to the trick with a dinghy pushing on the bow. Dennis C. Touche' 35-1 #83 Mandeville, LA
