There are right ways to do things and wrong ways to do things. Here is the very wrong way to pull a boat out of the water.
You have a large boat, it's basically yacht sized. The boat is on a trailer. The trailer is attached to a small tractor that cannot pull it out of the water on its own. The tractor is attached to another truck to help pull it out.
Right at the beginning you can tell that this isn't going to end well. It doesn't.
How the people on the scene thought that this would work is beyond me. Maybe they wanted to believe it would succeed so badly that they ignored all the obvious issues right from the start? That must be what happened.
