Lost both shrouds overboard upon disconnect from top of mast so I could not exaime for damage.
I need you to help me out here. The shrouds are attached to the hulls with anchor pins, twist toggles, adjusters, and clevis pins with ring dings. At the mast, the shrouds are attached to the mast tang with a large shackle and pin. This results in three attachment points.
You state that you lost the shrouds overboard, so I am guessing that all three attaching points failed. This must have been an extremely violent demasting.
I have demasted after having an anchor pin break, but I did not loose any shrouds due to the other connections. But the only thing that broke was the anchor pin.
I am tending to wonder if you had the boat rigged correctly with the correct hardware. You state that you lost both shrouds, but did you loose the forestay? If not, did you check to see if it has any damage at the top where it connects to the mast with the shrouds? Have you checked the mast tang for damage? Finally, you state that the starboard shroud let go due to the additional stress. There should not have been any additional stress as the leeward shroud always goes slack. The stress applied to the starboard shroud would have been normal stress.
I guess I just need a little more information to help you out.
