The Ghost Ship

Ahoy you landlubbers.

I see you want to join our pirate crew. It's not as easy as you think. You have to complete a risky task. Legend has it that a cursed ghost ship sails in the depths of the sea. Every 100 years, on the third full moon of the year, the ship appears and the cursed crew can go ashore. However, there is one treasure that is not cursed. You have to get it for me to become part of our crew.

The sailors of the ghost ship are currently on land to get a new supply of rum for the next 100 years underwater. It won't take them more than an hour to do it. So you have to hurry so you don't end up on board when the ghost ship sinks again and makes you scrub the deck as cursed slaves for the rest of your lives.
