In defense of the crew member he did disagree (albeit very vociferously) after executing the manoeuver. We then spent something like 20 minutes "debating" it, mostly with nobody including myself able to get a word in edgewise.
It seems like there's a definite consensus here so far. Thank you all for confirming my thoughts.
I do think it's a good point puddinlegs and jaschrumpf make. From now on there's a new rule on my boat, these debates are reserved for shore. I don't mind people asking why I want something but disagreeing with the skipper in front of crew and guests is not good for anyone.
