This story really hit home for me because one day during in our early, and less experienced, days of sailing my spouse and I were blissfully traveling down wind when we had an unintentional jibe in high winds. While I was at the helm of our Hunter 285 that we owned at the time the boom flashed across the cockpit narrowing missing my ”first mate’s“ head. In fact it went through the hair on the top of her head so it missed her skull by a fraction of an inch. Ever since then we almost always rig a preventer, only not doing so during a series of short jibes, and when we do call out for a jibe we also add the phrase, “Mind the boom!”
