Note: Legs' comment about not having to compensate for tides is inaccurate. The layout of the ship DOES allow for a simpler artificial gravity system, with one result being more available power for maneuvering and shielding, but during any sort of maneuvers the gravitic drive will produce tides that must be compensated for.

This is what the Drivetide Compensation Inertiics (DCI) are for. It's a tightly-networked system of small gravitic generators in the decks and walls that compensates for the tides generated by the gravitic drive of the ship. The DCI is a critical component -- without it, the incredible accelerations of combat maneuvers would exceed the Roche limit of the crew.

Addendum to Note: 21st-century astrophysicists understand the Roche limit to be the orbital distance at which a satellite with no tensile strength will begin to be tidally torn apart by the body it is orbiting. 31st-century DCI engineers understand it to be the point at which drive tides will exceed the tensile strength of individual crew members.
