In the Pirates of the Caribbean series, the ships have magical properties. Do these properties affect their speeds? That is, do they travel faster than equivalent real-world sailing ships?
But for the most part, no.
There's a total of 4 notable ships that we know of:
The Flying Dutchman
This ship can sail through the water and also ascend. It is almost always with the wind and because of this, it is usually always faster than other ships including the Black Pearl. Unless the Black Pearl has the wind and/or the Dutchman doesn't, the Dutchman is faster.
The Black Pearl
This was raised by Davy Jones himself after it got sunk as The Wicked Wench. As part of the deal Jack made to Davy Jones, The Black Pearl became the fastest ship, so besides the Dutchman with the wind, The Black Pearl is the fastest ship and is because it got risen as the fastest ship-this could be interpreted as using magic for its speed, I however do not as it's more of a passive thing and doesn't actually use magic at all, it's simply one of Davy Jones' powers.
The HMS Endeavour
This ship was the ship of Lord Cutler Beckett and did not use any magic whatsoever. It simply was built well and had a lot of firepower.
The Queen Anne's Revenge
A good ship, and seems to be able to be controlled by a magic sword, also known as The Sword of Triton. When near other ships, if the user decides, they can control the masts and ropes and everything about the ships. This ship was under the command of Blackbeard who could and did use the sword to speed up the ship. It is now under the command of Barbossa who also used the sword for the same purposes.
So do ships get a speed boost from magic? Answer:
Only when the Sword of Triton is near and is wielded to speed it up.
Otherwise, all ships rely on how they're built for their speed, but the Black Pearl and/or The Flying Dutchman remain the fastest ships.
The Black Pearl is said to be faster than most ships in the series, except the Flying Dutchman against the wind.
The Black Pearl was in its earlier life the Wicked Wench until Davy Jones saved it and Jack Sparrow from the depths and gave the resurrected ship magical speed.
