Bus being transported on four small boats - GIF

[Hoosiersmoker]

With the inner sides of the boats touching the underside of the bus, there would be little room for movement independently, the bus is the binder for this, I just hope the brakes hold! That's not 4 hp, that's 4 MAN power! so about 1/4 to 1/5 hp or less! Not sure why they don't just use on of the other boats to tow it and let the 4 guys just steer?
