This has been floating around the internet for a few days. I am not buying it...I think it's a hoax, good photo editing.
First off why would you send 2 cranes to do the job 1 can do? Second, come on, this is unbelievable...you think the insurance company would allow this?. Tide comes up, boat goes out, on it's own or with a good tow....why crush it.
Photo 1, 2 dark lines close to the stern hanging down...photo 2, no lines....plus the canvas in gone in subsequent photos...come on, are you really going to take the canvas if they are going to crush your boat...probably not. Take a closer look at the series of photos..in some there are 'thing's' on the boat and in some there are not. From photo 1 to 2 all this stuff appears on the boat.....
