struggle to understand how wreck trained and apparently experienced dives enter a wreck without a guideline.
I know that wreck quiet well, I visited it at least 15 times.
It is basically a concrete barge with two large compartments. As the ship is laying on its keel, these compartments can be visited very easily, by the large top openings, these are meters wide, on the deck. Just sink in, and get straight up again. It is like a hole with some overhanging at the sides and more ceiling in the front and back. I'm not saying this practice is safe, but it is easy. Most divers don't do this, but many do, taking a quick look. The ceilings are full of life. It is considered overkill to use a reel for this. But I'm not saying this is wise.
But, there is a third compartment, beneath the wheelhouse. The small opening is backways from the back cargo compartment, it is full of beams and fine silt. I never considered entering this place, but a trained cave/wreckdiver (I'm not) can of course. Then, there is the wheelhouse itself. It is a small house with a door and quiet large windows. Again, nice to swim through, but technically it is entering a wreck.
I don't know where the two unlucky divers were found or what they did before they died, only thate they were found 'in the back'. But being found inside the wreck says not much about the risks they took or what happened. One can assume, as they were not immediately found, one or both were well hidden in the smaller compartment. But if you don't know the place as a rescue diver or marine diver, you are reluctant to penetrate even in the larger compartments. As visibility is often low (1-4 m typically), it is very dark at 25m depth.
In one way or another they took a wrong decision, and payed a high price for it. I took decisions like that as well and probably often without knowing. As long as everything turns out well, we even don't realise it.
