I not saying anything about boats seaworthiness
In fact even with everything that happened, the boat was still mostly intact and floating, which says something.But, this is a valid discussion. What I am commenting on is that even with a rigging failure, by means of the loss of a single stay or shroud, a more conservatively rigged and keel stepped boat has an infinitely better chance of keeping his mast, which might be the only thing getting you home if you are way out there. I know of an 18 year old C36 Hull # 206 (they are up to about 2200 of them now) that had a major rigging failure which happened in about 7-8 foot seas at 2am in 20 kts of wind. They were racing offshore when it happened. The stem fitting broke letting the furler and sail fly off into the wind. With a little quick work they were able to save the mast and still get back to port safely. (see http://users2.ev1.net/~barr/c36rigfailure.htm for pictures and story) I believe they were able to save the mast, even with a catastrophic failure like they had, due to the fact that this is such a conservatively rigged boat. This was due to the boat being keel stepped but *also* because this boat has both a forward and aft spreader stay. Even with the total loss of the forward stay this boat still has the forward spreader stay which helps keep the mast from falling backward. Compare that to the Hunter's B&R rig . It has no forward spreader stays, it achieves the forward "push" on the mast from compression on the angled spreader with the side stays (shrouds?) . I really doubt there is a skipper out there that can keep a mast from coming down on this boat if it loses a stay out on the water. (One exception to this logic, though, is if you actually roll the boat 360 degrees, then I would rather have a deck stepped mast and have the rig come off completely than potentially rip a bigger hole in the deck, but this is even a lot less common than having a rigging failure)Don't get me wrong, there are advantages to the B&R rig, the backstayless design allows for a bigger mainsail, it also allows for a smaller diameter mast which helps reduce weight aloft, etc. But if you lose a stay or shroud out on the water, you are in trouble. It has been said many times before. Every boat is a compromise, this is one of them.BTW Obviously there was a defect in that particular boats stem fitting and I know of no other failures of this type and anyway the newer C36's have a completely different design these days. But anything can happen out there, and its nice to know and be ready for what can happen.
