The concern was that if the boat needs to be turned upwind to ease pressure and drop sails/reef/furl/etc that there could be a risk of broaching as you turn through the following seas and winds.I thought others were saying that while running downwind that if you were moving too fast that you ran the risk of ? broaching? Not really sure if that was the risk or maybe I was just misreading it.
This could be applicable for me if I am running to harbor on the MS coast and there are no natural inlets to break the wind and waves--just miles of straight beach line. I'd just come screaming into the harbor entrance which is a man made dog-legging funnel with tight jetties on either side, and right there the chop kicks up in a nasty way. Other traffic at same time? I might be better off if I could come about and drop sails before entering harbor inlet.
But the OP's assumption of really snotty conditions makes coming about a potentially unsafe maneuver.
Hmm, glad someone brought this scenario up!
