A roof taking out the rig must be considered a rare event offshore and I am sure the designer didnít consider it as a mode of failure to investigate when designing the rig. At least I know itís not a condition I ever looked at when designing a rig. I think it might be difficult to find an answer to a question like this if you fall back to discussing specific examples. You can always find plenty of good examples to support both sides. I think a more abstract view is a better way to go because the answer is an opinion and not something that can be calculated or defined.
To me itís simple; if you tie the two together you have a chance of dragging one mast down with the other. If you keep them separate then they are each unaffected by what happens to the other. Of course if you do something global to the boat both spars are on the same boat so if you sink the boat both will sink or more realistically if you roll the boat you might lose both no matter what the configuration is. But if they are separate at worst they will fail separately or at best one will survive.
You said in part, ďI'm not sure theres a definitive answer here except that the triatic wouldn't be there is the designer didn't feel it was necessary for the particular design of a specific rig.Ē and I think thatís very true. You can design a boat that needs one and you can design a very similar boat that doesnít but if it was considered necessary by the designer then you can be sure he wanted it and you should take care and think carefully before changing the design of the rig.
All the best,
