Continuity mistake: When Tom Hanks is in the dinghy by himself, the outboard motor has no cover. He falls into the water and the dinghy circles him several times. One of the shots shows the motor with its cover in place. (It is an Evinrude motor).
The government finds out that Madison is a mermaid, and she is hauled off to live in a lab tank for studies. Her boyfriend Allen and his brother Freddie (both human), disguise themselves as scientists and sneak Madison out of the lab. Madison and Allen then go to the ocean, thinking about either releasing her back to her ocean life or staying human and living with him, but they must make a fast decision because they are surrounded by the people who captured Madison. Allen then jumps into the ocean with Madison, and they swim around down there together, choosing to stay together forever.
Guardsman: Hey, you! Move that cab out of here, right now.
Vinny: Up yours, Gomer. I'm waiting on a fare.
Trivia: Darryl Hannah had to wear a specially designed synthetic hair wig for the underwater shots. Notice that her wavy hair stays wavy underwater; real wavy hair goes straight underwater.
