Continuity mistake: When Bligh is pumping the patch up on his inflatable boat, when it shows a close-up of it, there are empty black hooks underneath it. Yet when the patch bursts, there is now white rope running through the previously empty hooks. (01:19:25)
Continuity mistake: When the shark is attacking the catamarans with the teenagers aboard, in one shot you see Andy fall backwards, still on the catamaran, and he is barefoot. He is then knocked in the water, and when his friends pull him back out of the water on, he now has white trainers on. (01:20:10 - 01:21:15)
Continuity mistake: Just before the shark knocks Doug off his boat, the sea is somewhat rough, with a wave line behind, but in the next shot, as his boat capsizes, the sea is much calmer and the wave line disappears. (01:23:35)
Continuity mistake: When Brody is out looking for the teenagers on the police boat, he is shown approaching the lighthouse while passing a buoy on the left of screen. When we see Brody and the police boat from behind the top of the lighthouse, there is no buoy anywhere. (01:23:55)

Continuity mistake: Brody has a hold of the large power line, and the shark is gliding along straight for it. In all the shots of Brody holding the power line, the green jacket he wears has wet splashes on it. One patch of water on his right shoulder briefly disappears for one shot, the reappears in the following. (01:46:45)
Continuity mistake: When the kids are drifting around, a heavy rain shower comes. Seconds later, in the shot of Sean on the upside-down sail boat, you see reflections of sunlight and a large part of the boat he is sitting on is completely dry.
Continuity mistake: When Brody and his wife are driving towards the harbour just after the diving accident, the sky is overcast. When they get to the harbour the skies are clear. When they sail away in the police boat the sky is overcast again.
Continuity mistake: In the scene when Chief Brody, his wife & deputy come across the sail boat named "Tina's Joy", they find Tina in it, and during this scene Chief Brody's jacket is placed on Tina's shoulders. The Chief then leaves the sailboat in search of the other teens. Later scenes show the Chief wearing this jacket when in fact he left it with Tina.
Continuity mistake: At the end of the movie when the Chief has killed the shark, you see his son Shawn cheering, with his hair completely wet and messed. By the time the Chief paddles over, Shawn's hair is now perfect; dry, and combed neatly...
Continuity mistake: When Brody is out looking for the kids, and he sees Mike's boat approach - the sky in the background is overcast. When they meet, the sky is clear.
Continuity mistake: In the close-up scenes at Cable Junction, with water, the sky is clear. But in the scene where Brody is climbing on to the cable, the sky in the background is completely gray - and actually looks like a studio wall.
