Continuity mistake: Between the time the Professor is put into the trance and waking up, his mouth mouth goes from agape, and head turned to the left, to mouth closed, facing forward.
Continuity mistake: The professor is put under a trance, referred to as "zombiefied." When it first happens, the professor is looking to his left. Later on, he's looking straight ahead.
Answer: Hungarian-to-English translation aside, Erika's log-book entries were utterly meaningless. When the radio interviewer expresses confusion, Erika even reads entries from the log: "You take a left at a big, beautiful, pink tropical flower, then pull over and park," and "After the storm, we backed up and made a U-turn," etc. Her directions were scatterbrained, to put it nicely. Additionally, Erika's yacht was forced to leave the island during a tropical storm, and they lost their bearings for several days before the Navy found them. Given that Erika was such a scatterbrain, we might also assume that she didn't hire the most competent yacht crew, either.
