Even funnier! Two morons in one post.
Name calling is not a very appropriate response to a couple of posts meant in good humor. Chill out a bit and give it time and you'll get your answer. The two other guys DID NOT throw personal attacks at you they made light humor yet you respond with personal attacks and name calling..?
You really need to be careful with this type of name calling behavior & personal attacks as it will get you banned on some sailing forums.
As for the goose neck there is no one single answer as it depends on a lot of variables. End boom sheeting, mid boom sheeting, rigid vang, soft vang, loose footed main or bolt rope foot, where are the reef lines led, cunningham, out-haul tension at the time of failure...etc.
I have had a goose neck fail while close hauled in about 20-23 knots. Because the boat was mid boom sheeted, with a rigid vang, and had reef lines attaching to a cleat on the mast near the goose neck, with one in use and under load, nothing really happened and I did not rip or tear the sail. The boom at the goose neck end merely went to leeward by about 5" and back about 3". My first sail slide was about 14" up so allowed for this. The vang was pushing away from the mast and the mid boom sheeting helped balance the load somewhat and did not force the boom forward or back enough to tear anything.
I simply rounded up, dropped the main and then fell off using only the genoa. I then pulled into the next port and fixed the goose neck and was back underway in about an hour...
After dropping the main and once back under way, and while still at sea with approx 4-6 foot seas, I slid the boom back onto the goose neck and then lashed a line around the mast securing the boom by pulling it "into" the goose neck to keep it there for the time being.
A failure of a goose neck will be slightly different on every boat depending upon how it is set up, what point of sail you are on etc. etc.. Some failures may rip the main or at the least pull sail slides off some won't. Not a exactly cookie cutter answer..
I'll have to try an find some pictures of the failure. The failure was a piss poor design by the manufacturer, IMHO, which I addressed and changed that winter.
Found the pic.
Removing the booms end casting:
Failure mode (cotter pin used for hole was to small and a poor/weak design to boot):
Working the repair in port (the red line dangling over the port genny sheet is what was used to lash the boom around the mast at sea):
