Translated ... In order to reach the cement factory, 3rd level ships are needed.
There are 2 ships in level 3 in the fleet. But I can't get to the sea. The fleet is full.
How to bring these ships into the sea?
Remove 3 sailing ships by tapping the purple down arrow to remove them to drydock. A 3rd level ship takes up the space of 3 sailing ships.
To add both level 3 ships, you will need to remove 6 sailing ships.
