how I sell a ship. I do not need some ships
pixel_player843949237 museum! But be careful, once in you can’t get them out! I put my entire sailing fleet in the museum and then a game update add it map exploration and had to invest in an entire sailing fleet of 1 slots. Very costly and time consuming.
You can't. You put them in the museum.
You don't. You put ONLY the ones you will NEVER use again in the museum otherwise you keep them in drydock where they don't bother anyone.
