The chance of receiving goods varies. You can load ingots onto ships while preparing them to increase your chances of receiving rare goods and treasure chests. Tap a product on the island screen to see whether its drop rate is low, average, or high. Ingots are twice as effective when using the Favorable Voyage booster at the Laboratory.

You can also speed up a ship’s return using T-Cash if you don’t want to wait.
