Corrected entry: When the scientists go into the black lagoon, their boat is named Rita. Their lifeboat is also named Rita. All boats are given different names, so it would be impossible for the lifeboat and the boat to both be named Rita.
Correction: There is no law requiring boat owner to give each craft a different name. I bought a boat off someone who named the boat their mother's name. The new boat that replaced the one I bought was christened with the same name. And we were at the same lake.
Correction: The lifeboats on the Titanic also had Titanic on them. It is simply to show where the lifeboat came from.
