Of course, StarTrek ships are tiny compared to Culture ships which are measured in kilometers - the largest StarTrek ship could be displaced into just one bay of a General Service Vehicle ... StarTrek ships are also much slower using ancient warp tech. Then again, StarTrek ships use obsolete computers to run them, while Culture ships use a self-aware Mind(s).
