Alex has made a point often unseen by those not involved in accident investigations. I've been involved with a bunch over the years in one capacity or other and the most common reason an incident occurs, is a skipper trying to meet a schedule. The push out into weather they shouldn't, because they need to be someplace at a particular time and the weather isn't cooperating, but they go anyway. Some try to out run a system, for the same reasons, not wanting to lay off for a half day, waiting for it to pass, etc., etc., etc. Compliance and overconfidence are big players too. We lost the Bounty replica to these reasons recently. Mix this into a tight schedule and the sea floor is littered with the results. An experienced skipper can recognize this and makes an appropriate decision, but you do need to have considerable time, farther from shore than you can swim back to.
