Sure make me go read the various iterations of Pilot and Shipsboat. The biggest difference is in handling.

Note in one of the early adventures air/rafts in zero g required Shipsboat skill to operate.

Also note the skill acquisition tables pilot generally on the advanced education table (edu8+)

Shipsboat also talks more about aerospace operations, while Pilot briefly discusses atmospheric flight, it primarily allows the operation of the Jump Drive..

Evyn.
