Maybe there could be curses for ships that are unlocked simultaneously to their pirate equivalent.
Megalodon curse: makes the inside of your ship look like the whale scene from Pinocchio. The exterior keeps its livery but it becomes scaly. The turning thingy on the bottom resembles a shark fin.
Ghost curse: makes the accents on the livery glow blue (by accents I mean the planks that are the gold part of the golden sailor hull)
Skeleton curse: makes accents white with a bone-ish texture
Legendary curse: adds a glowing Athena symbol on the side of the ship
Ashen curse: makes the spaces between the boards appear orange
Sunken sorrow: puts coral sticking out of your ship’s side
Lightning curse: gives the figurehead a lightning effect similar to the effect it gets in hourglass.
Stone curse: makes the ship stone
Curse of the order: makes the deck covered in kraken ink
