Factual error: Most uniforms in this movie are worn incorrectly. Between wearing belts incorrectly, not wearing ribbons on dress uniform (shore patrol), female hair regulations, shoes, and having ribbons in the wrong order it's like they didn't even try.
Factual error: Sometimes when we see the USS Stingray sailing south we see land to the east which would mean this would be on the west coast instead of the east coast (The original ship was the USS Pampantino which sailed off California in WWII).
Character mistake: While the engine room is flooding, Stepanik tries to put a jubilee patch on the pipe by walking towards and deflecting the water. While it looks cool for the movie, it is definitely not the correct way to apply this type of patch.
Answer: Dodge says "We live to fight another day, Captain." suggesting that the photo is of the previous captain of the Stingray.
