Pirates of the Caribbean Compass Continuity Errors
Continuity mistake: After Carina tells Jack and the others that she's an astronomer which has nothing to do with donkeys, when Jack threatens to kill Henry in the shot facing him he's holding his left hand up pointing at Henry, but in the next shot facing Henry it's Jack's right hand up pointing at Henry.
Super Grover 
Continuity mistake: Near the beginning of the movie, when the young adult Henry attempts to stop the British Captain from sailing into the triangle, Henry is subdued by the Marines. The British Captain accuses him of treason and rips both of Henry's sleeves down from the shoulders. The next camera view is from slightly further back as the British Captain commands the Marines to take Henry below and Henry's sleeves are still intact.
Continuity mistake: After Barbossa releases the Black Pearl to her former and rightful glory, when it cuts to Jack and the others running on the beach the closeup and next long shot are flipped shots. Note that even though they're flipped shots Barbossa still has a right wooden leg, thanks to the CGI. (01:23:30)

Continuity mistake: When the sharks attack Jack and Henry's rowboat, one bites a chunk of the stern and the hammerhead bites a chunk of the bow. In following shots the bow bite vanishes as the shark leaps over Jack and Henry when it lands in the water, and the damage at the stern not only changes, but it also vanishes when the shark imitates Bruce from Jaws and lands on the boat.
Super Grover
Continuity mistake: After Jack uses his spyglass to watch Will and Elizabeth reunite, when it cuts to Gibbs shouting, "Make way, Captain Jack Sparrow on deck," the shot of Gibbs and also the next six shots are all flipped shots, until Jack reaches the helm. In the first two flipped shots of Jack the beads and bone that are at the top of his head have been digitally altered to the right side of his head so the shots appear normal, but everything else is backwards.
Super Grover
Continuity mistake: When we see Jack inside the bank with the vault, there are three windows in the wall at the back of the room, but when the back of the building is seen with the pirates and horses, there is only one small window high up on the wall. (00:16:45)

Continuity mistake: The cross like scar next to Jack's eye looks completely different in this movie to how it looked in "Stranger Tides"
Continuity mistake: Jack's knuckle tattoos on his right hand read "Jack" and the knuckle tattoos on his left hand read "Jakc" with the "k" at his ring finger and the "c" at his pinky. The ink intensity and letter style of his tattoos keep changing, and during the scene in the bank the "c" and "k" tattoos on his left hand have switched places, with the "c" at his ring finger and the "k" at his pinky.
Super Grover
Continuity mistake: When Carina escapes from her jail cell, just after we hear Mayor Dix dedicate the Royal Bank of St. Martin, in the closeup we see the locked shackle around Carina's left wrist and the hanging links with the other shackle dangling. Then when Mr. Swift sees Carina handling his telescope, in this closeup we see the shackle links are hanging the opposite way, revealing that the locked shackle around her left wrist had been the dangling shackle from the earlier shot.
Super Grover
Continuity mistake: At the end when they board The Black Pearl from the anchor chain, all of the characters are virtually bone dry despite being soaked and submerged by the sea. Henry's sleeves are blowing in the wind.
Continuity mistake: On the guillotine platform, when they strap Jack to the bench which will support his body, we see the double prong buckle is attached to the short leather strap beside Jack's right arm, and they slide the long strap with holes through the buckle frame. However, in following shots when Jack is on the ground the double prong buckle is actually attached to the long strap, and it's the short strap with holes positioned within the buckle frame.
Super Grover
Continuity mistake: While the Pearl's crew are battling Salazar's men, after Mullroy asks Carina if she's found what she's looking for and she shouts that she's trying, when it cuts to Barbossa fighting it's a flipped shot. Also, note that even though it's a flipped shot Barbossa still has a right wooden leg, due to CGI.
Super Grover
Continuity mistake: While Jack is being dragged behind the bank during the robbery, there's a closeup of Jack as he tucks his rum bottle away, and a few shots later when the Royal Marines are running from the right side of the screen to the left, this shot is flipped. Note the direction of their distinctive crossbelts and tricorne hats.
Super Grover
Continuity mistake: After Jack and his crew take Henry and Carina prisoner to lead them to the Trident, when they're aboard the Dying Gull, Jack pushes the two ladders to the ground, but when the line is cut to release the ship the ladders are still leaning up against the vessel.
Super Grover
Continuity mistake: While Jack argues with Gibbs during his rescue from the guillotine, in a wideshot Jack falls over two caskets which have a distinctive shape, but their direction faces the opposite way in the next closeup.
Super Grover
Continuity mistake: After the bald witch walks towards a wall with stars painted on them, there's a shot of Henry threatening Jack with his sword. The grip on the sword and the position of the arm are not continuous between shots.

Trivia
Trivia: The ship we see Jack on in Salazar's flashback is called the Wicked Wench. This is a bit of an in-joke for PotC buffs, because that was the original name of the Black Pearl before being sunk by Cutler Beckett and raised again by Davy Jones. It's fully explained in a deleted scene of At World's End.

Questions
Question: At the very beginning of the film, young Henry boards the Flying Dutchman to speak to Will. When Will looks behind him, he sees the shadows of several crew member starting to make their way towards him and he suddenly gets frightened that the crew will see Henry. Why would he react this way? Since he's captain of the Flying Dutchman, if his men saw Henry, Will could order them to leave Henry alone.
Answer: He's probably worried that either the crew will attack or at very least frighten Henry. Or he just doesn't want Henry to see how horribly the curse can affect people.

But because Will is ferrying souls to the after life, like Davy Jones should have done for the full time, he was captain of the Dutchman. There is no curse that would make the men look like sea monsters. They only started to look like that because Jones denied his duties after 10 years of service, when Calipso didn't show up. So the crew would look like normal men, so Will being worried that Henry will be frightened by them, can't be the reason he started to panic.
