Jerry's absolutely right, unfortunately, phrased in a way that's hysterical, IMHO!
The Cliff Notes version (uh oh, that may send some to Father Google) is we were on port tack, double reefed and headsail furled (a bit) in 18-20 knot wind on lumpy/sloppy Lake Michigan 4'-6' square waves. We were saling to, or beyond, our polars in these conditions at @ 6+knots Those that have experienced these waves and conditions know they are not fun. There was no excessive weather helm, inducing a bit of spray as we punched through the random wave crest we couldn't avoid. Late afternoon/early evening July overcast sky daylight.
At 6:45 PM CDT, with 5 of the 6 working the boat: (3) on the rail, (1) running mainsheet, (1) on the helm and 1 below deck resting...the rig came down, on starboard, perpendicular to the boat. In less than 2 seconds, with no loud bang or pop. Just went.
The crew member below deck came up, all crew in pfd's. The boat, eventually, stopped. We marked our position as a MOB, called a Pan Pan on the handheld VHF and began to assess. The 1st item, all (now) caught on GoPro, which someone had the sense to turn on, was to warn all crew 'do NOT put yourself inside shrouds, halyards or running rigging, just in case the rig goes over the side unexpectedly.'
We disconnected the forestay/furler, detached the backstay, saving the Navtek adjuster. The boom was disconnected and put to the side. There was no chance of saving the mainsail or the headsail. The mast sheared off @ 6" above the partner and was probably bent/fractured at the top spreader, probably the result of a failure at D2. We'll never know for certain, unless someone dives the lakebed and retrieves the rig. Not happening...
The base of the mast was the most dangerous component, the lumpy/sloppy waves causing it to flex, torque and move. It's movement was somewhat prevented by the jib halyard and 2 of the port side shrouds. We freed up pieces and parts sequentially and carefully, until it "came time", with the forestay and furler thrown off, followed quickly by the pin holding the turnbuckle of the final port side shroud pounded out. The rig at this point was almost free, just the jib halyard holding it in position, which was frayed and taught, incredibly taught. The knife barely touched it and it went 'Ping!' and the rig was free, kicked over the side without touching the hull. The vang, the last item to go, was initially snagged, then cleared and thrown off. The rig sank out of sight in less than 5 seconds. Gone.
We waited @ 5 minutes for 'it' to sink some more and also allow the boat to drift away from the event area, verified that were no halyards or lines visible, perhaps said a silent prayer and then engaged the tranny to begin a 4 hour slog home in quartering/wallowing/lumpy waves @ 6.5 knots. Ugh.
The CYC Race Committee was called as soon as cell connection was available (@ 10 PM), 'cuz the rules state you've got to call them to announce your retirement. The RC member that answered, a very comforting voice to hear, eventually stated "we were expecting this call, cuz we were monitoring your YB track". Funny.
There's still some Mac paperwork to complete, and then the mountain of other paperwork. Ugh. The numbness is subsiding.
