You went ahead and posted almost the entire story here in one go. I've found that when posting in a forum like this, it is more beneficial to post in segments. This way you stand a better chance of getting constructive feedback and avoid the risk of the story dropping off the front page too soon.
Having said that, I've really enjoyed what I've read so far up to Chapter 6. We don't often get to see a fire and brimstone type captain who sounds more like a drill sergeant than a refined gentleman. It an interesting approach and certainly appropriate considering this crew misfits and under performers.
I'll try to catch up with the rest of this tale, time permitting.
