By pressing the [Dock] button in the NPC conversation window when talking to the dockyard owner, you can move to the dock to build and tune your own warship. Building a ship is simple - just make sure you bought or found the essential parts. Follow these steps to build your own warship.
 

Step 1: Place [Frame] parts at the available dock slots.
Step 2: If you register a [Frame] part at one of the dock slots, you can start to compose your warship. Right-click on the desired warship parts in your inventory to add them to the "Parts" window.
Attention! You can only construct ships with parts of the same class and level. It is not possible to combine various ship types. Please keep that in mind before purchasing ship parts! Step 3: Once you have finished the construction, press the "Tuning" button to complete your warship!
