I had a shroud break on my 5.2 when landing on a beach in about 4ft surf, 15knt winds, so not crazy at all. Anyhow, i was upwind but no complete close-hulled. The mast came down violently. Luckily it fell away from us, but i think that a person on that side of the boat would have suffered significant damage. the only damage to the boat was a very patchable hole in the mainsail where the dagger baord punched through it, and of course i replaced all my shrouds.
