My decks are shortly approaching the point of a ship upgrade. I was hoping to keep my ship size at it's current stage for a little while. What I'm wondering is will my race bonus of '+10% ship size' count towards my ship upgrade, or will my ship size be based on the decks listed in the 'Ship Crew & Size' tab?

The "Space" indicator, and the number listed in "Ship Crew & Size" are two different numbers. What I'm meaning to ask; is if the "Space" indicator, that shows the amount of available decks that can be used(after adjustment from the Sillixx 10% bonus), has any bearing on the size of the ship?

For example: When the amount of decks in the "Ship Crew & Size" tab reaches 44. The "Space" indicator - which is described as "The amount of deck space available on your ship to install modules and weapons", will be at either 48 or 49. What I'm wondering is; if the "Space" size were to be increased to 50, by bringing the amount of decks listed under the "Ship Crew & Size" tab to aprox 45 or 46. Will the amount of 50 - indicated next to "Space", cause my ship to upgrade from a Scout to a Light Frigate?

When you are NOT Sillixx, the true number of decks you can use is equal to what it shows in the Crew manifest. As already stated by someone earlier in this thread, get away from Sillixx ASAP. The later you switch, the harder it becomes. You either have to uninstall equipment from your Sillixx build until you meet the unadjusted deck total, or you need to stockpile enough ship bots and/or rank points to make up the difference.
