It sounds like Marc is making decisions that I think ignores any warnings from his Captain and crew otherwise I don't think they would be stuck now if Marc heeded the crew advice. Devlin even pointed out flaws in Marc's actions there's this exchange
“Oh, I don’t like the sounds of that, sounds very unsafe,” I commented, “I must admit, it will be a new experience for me too, but since Rebecca and the boys safety is at hand, I decided that it was worth taking the risk,” Marc stated. Why don’t we just find a small cove somewhere, that is easier to get in and out of just in case we are discovered, since there is no means of escape if they do find us?” I commented. On better reflection, you may be correct there, but we may be a bit too late now,” Marc commented
I appreciate that Marc is doing things to make Rebecca and the boys safe and harder for the bad guys to find but putting the ship and everybody aboard it at risk is not the way to go about it.
I was surprised that Devlin found a place on the yacht where nobody could find him.The 2nd officer eventually found out and promised to keep it to himself.I'm worried at a future time Devlin will be hiding there while something is happening to the yacht and the 2nd officer won't be able to tell them where he's at because something happened to him
