The Main Dock is a building that increases the number of slots for ships in the fleet. The more slots you have, the more (or bigger) ships you can place in the fleet.

When the Main Dock offers 8 slots, it means that I can put in the fleet for example: 8x 1-slot ship or 4x 2-slot ship, or 1x 8-slot ship.

If you don't have a completely full fleet, the game shows you the possibility to manage ships at the dock.

It is one of the three buildings that is outside the construction grid and cannot be moved.

UPDATE March 3, 2025

We've added a system for increasing fleet size to better align with the rest of the mechanics we've added along with the 9-slot ships. We have now set the size increase to 12-slot ships. We will monitor this system and inform you of any changes.
