As above the master of the vessel is ultimately reponsible for vessel and passenger safety. Any negeliance or obvious oh&is that's overlooked will be to his/shipping lines detriment. Not my rules just the way it is. Just like the common carrier rule with TNT etc all T&Cs to cover their arse to the moon. Keep pushing when your parcel is lost by them and eventually common law over rules and they are at fault cause they promote themselves as "carriers"
Jim is 100% correct. The skipper is to blame, legally. .....
FFS, You're driving a vehicle onto a boat off a beach, onto another beach. There's no yellow lines painted on the sand and the last outgoing tide took all the safety signs with it.
If you can't safely PARK a vehicle, let alone one on a moving vessel, then hand your licence in, if you have one.
At the end of the day, the Skipper is responsible. Had the ramp been up, the vehicle moved and killed a kid, again he's responsible. If it moved and hit the car in front of it, the owner of that car belted the clown who didn't park his vehicle correctly, again he'll no doubt legally be held responsible.
Take me back to the 80's please......... When not only cars were cool, but people were actually accountable for their own stupidity.
Of the last million vehicles on that barge, how many fell off? So it's a ? In a million chance.
Some people should not touch a motor car, let alone drive them.
