Why can Davy Jones stand on land only once every 10 years?

Davy Jones can only stand on land once every 10 years due to a curse tied to his role as the captain of the Flying Dutchman. This curse forces him to serve the ship and the sea, preventing him from fully enjoying terrestrial life. The decade-long interval acts as a binding condition of his pact, reflecting the themes of duty and sacrifice prevalent in the lore surrounding his character. As a result, his limited time on land underscores his tragic existence as a cursed sailor.
