They are below deck plotting a raid on a certain man from Mars.  If you would notice 5 out of 6 of my ship images have at least one crewman visible.  hrump... you been itching to use that chair again? 

I do agree with your observation and I considered adding some peeps to this latest image but there was ony one place that they would be visible, near the bow, because the crow's nest is obscured from view. Otherwise, men would not be aloft if the captain was not preparing for a manuever.  Soooo, I hereby declare this captain was on an easy down wind run with clear water ahead and the crew was hung over from drinking rum.  Whew.  Cardinals from Mars...
