The stats page and ship info list the Starfarer and Gemini as having the same weapons, engines, and mass. Is this an oversight? If they haven't yet been determined, it's ok to tell us, it would be a lot less confusing.

This is an oversight - the Gemini has one size larger turrets and engines. Because the models are very similar and components have not been finished, it's not possible to measure a more accurate mass yet.
