Factual error: As the two fast boats start heading up river towards the finale shootout, one boat has its navigation lights on incorrect. It has a red light on the starboard/right side, and a green light on the port/left side. It should be the other way round (the lights on the other boat are correct).

Continuity: In the series of shots when Crockett and Tubbs have phoned headquarters there are several large red LED clocks in the background. The clocks jump ahead a few minutes with a few seconds on the phone but the funniest clock change is at the end when the minutes showing actually go backwards from 49 to 48.
