Mrs. Allworthy puts lip rouge and a beauty mark on Moll. Moll wipes off the lip rouge walking down the stairs but not the beauty mark. When we next see her face, the beauty mark is gone.
The motion of the ship below deck is unrealistic. At 0:32:00 and 1:50:00 the scene inside the cabin shows rocking along one axis only - side to side - when the ship was in a storm. Anyone with practical experience with boats and ships in the rough weather depicted would expect pitching fore and aft as well, and violent crashes from bashing into waves, creating a corkscrewing roll that contributes so much to seasickness. Also at 1:50:00 an exterior shot of the ship in the storm is accompanied by a command "reef the mizzen mast" but the sails are hanging limply; the heavy roar of the wind suggests they could not be in the eye of the storm.
