Holds are the amount of cargo space your ship has, the more holds you have the more
cargo you can carry, it is advised that you max out your cargo holds as soon as possible
in the game to make more money. Your current amount is shown in yellow,
and the maximum in white.
Hold upgrades can be purchased from the Equipment Dealer at any station,
remember that the more holds you have on your ship, the more you will have to
pay for an upgrade!
