Wonder if Cape Air guys can answer a question for me.

I'm long removed from the 135 world, but my son has about 100hrs and is finishing college. We were talking about the new 121 time requirements and the paths available to logging 1500 hrs. He mentioned that Cape Air had 402 F/Os and I was surprised at that, I thought they were single pilot. So, the question is, can Cape Air F/O log SIC time? Are there no autopilots in the aircraft, thus requiring a F/O. I once flew a B-99 as F/O and that was how I was allowed to log SIC time.

Thanks
