Ummmm...wow. Was there some major event that led to that damage? That looks pretty serious to me. That bulkhead is responsible for distributing the load from the main beam evenly to the hull which then carries the load to/from the shrouds and bow chain plates. It can experience both compression and tension depending on what the boat is doing. I'm no expert however. The question would be what kind of ultimate failure scenario would result and my guess would be that the hull would collapse with a potential for taking on water and/or dropping the mast.
