The Beast is a really good movie.

The master of sea terror, Peter Benchley, returns with another salty tale of aquatic mayhem! Rocked by mysterious deaths and disappearances, a small fishing village looks to Whip Dalton (Emmy nominee William L. Petersen) to get to the bottom of it. Little do they know that the hungry beast that hunts their waters is a blood-thirsty giant squid.
