That doesn't look very safe! Nice ship though.
When the old Queen Mary was bringing back American servicemen after the war they all wanted to see the sights of home entering harbour and crowded over to one side causing the ship to list. They had to be ordered back from the rail.
Also, when PS Waverley does a round the Isle of Wight trip and is fully booked, everyone wants to look at the view on the landward side which causes the ship to heel so that the paddles are not evenly immersed and the ship moves crabwise through the water.
