How do I operate this ship~?

Ships are unlocked starting at level 29. Clicking on your ship at the dock and upgrading it with ingots will give you benefits like reduced time and increased rewards. Make sure to manage your resources efficiently, hmm!

Ships are unlocked when they reach a certain level. If you send a ship from the dock, it will bring back fruits after a certain amount of time. You can upgrade them slowly, but I'm not sure about the exact level, so I'm just giving a general explanation.
