Margarite's Occator now has rigs and can hold 35 K cargo now.
The most expensive parts to building cargo rigs are the armored plates. Margarite bought the amount she needed to build two rigs for her Occator. The Occator was a planned ship a long time ago and of course her tractor beam business plan supported it. In the end it is more likely that what actually paid for this Tech II transport ship and now the rigs she just built are her corporation production wages. At any rate her number one transport can now carry 35 K of cargo up from its previous 26K..
