Hold that boat.

Watch as a man detaches his boat from an SUV and then holds onto the boat as it gets away from him.

Apparently, the guy parked on an incline and when he detached the boat from the vehicle the boats weight carried it downhill.

Well, the guy wasn't going to go down with a fight. He held onto his boat until it came to an abrupt stop on the street.

It doesn't look like the guy wasn't severely injured here, but he sure did put up a good fight against gravity.
