Ship Improvements

Ship improvements are improvements you can buy for your ships in the game. These typically are somewhat expensive, but cost less than hiring specialized staff. Ship improvements are located at the bottom right of the screen and can be applied simply by clicking on them and purchasing them. Each one gives an additional passive benefit to your ship. (the exact extent of each one is unknown)
