We have done the Spiegel on two occasions. The first time there was zero current. We were told the current could change on a dime and went down and up the line accordingly. The second time, last summer, I was the first person off the boat and had not been warned that I was jumping INTO a fairly strong current. I did my giant stride at the back of the boat, and the line I needed to swim to was perpendicular to the boat (I found out AFTER I was in the water). A younger, quite strong dive guide jumped in and pulled me to the line. Going down the line we were like flags in the water. By the time I got to the wreck I was exhausted and frankly, should have called the dive. But once I saw the first entry point to the wreck I calmed down and was fine. Going back up there were people climbing over me on the line to get to the surface. Very uncomfortable, but by this point I was ok with my skill set and not exhausted, so all ok. I was more worried about the yahoos climbing over me to get to the surface.
If this 67 year old man experienced what I did - and jumped in away from the line leading him to the line down to the wreck, I can understand why he would be stressed and panicked. If I were not in as good of shape as I'm in (and it ain't stellar!), I wonder how much more difficult that could have been for me.
The Spiegel should not be 'sold' as 'just a wreck dive'. It's not the Kittiwake! If the current is 'sporty' it will be difficult for those who are not in great shape or whose health is compromised. I won't do it again. I'm too old and/or not in good enough shape to fight that current.
Condolences to the family. Tough all the way around.
