People who cruise boats are independent and are fine with the concept of being self-sufficient by their nature. Otherwise they would not be comfortable in cruising, let alone find the experience appealing.
That bleeds over into confidence. Which bleeds into strong opinions. Nature of the beast.
Not always right, but never in doubt.
And in the practical REAL world, off-line with no web page debates, running a boat, that's not bad. At all. I watched one video done by a recognized name, and the "host" asked a skipper how he trained fresh guest-crew, especially in docking. The answer was "there is only one right way, and its my way". The host was taken a bit aback and the skipper explained. When one later has to come on deck in weather in the dark and adjust something, there ought not be fumbling around. One Right Way, and you know what it is and what has to be done. He said there may well be better ways, but His Way made for valuable consistency. He had a good point. I wouldn't do it His Way myself, but I would on his boat, and for his reason.
