As long as we are guessing I will say the boat came unhooked from the ball of the tow vehicle
T'were my 1st thunk.
My guess....the trailer is still hooked to the truck, ( you can not see the truck ) said driver dynamited the breaks, back of boat not tied down, front of boat pitches forward lifting the back of boat, inertia of boat swings to the right..over the guide rail and trailer fender...bam..hello pavement.
