I don't doubt the picture. This isn't a very big car.
A lot of the weight is still balanced on the dockside.
The boat is listing a little but keep in mind the weight on the side of the boat might be + or - 1000 lbs. That would be the weight of 5-6 men.
A big boat like that wouldn't list that much with 5-6 men standing on the side.
The only thing I would doubt if the driver is really the person pictured.
