Personally, I was very disappointed when I first saw that they were removing the stacks.
Those are THE iconic feature of that ship and it would be cool for those to be your first sight of it on descent and your last view of the wreck as the diver ascends
While I agree that would be cool, it would put the deck of the ship near the limits of recreational diving and the vast majority of the structure outside of those limits. The stacks are 65 feet tall. The ship needs to have 50 feet of clearance from the surface. That would put the deck at 115 feet. With the funnels removed, the deck will be at 50 feet, leaving way more of the ship available for recreational divers to explore. I think it is worth the tradeoff.
