Sailor Steve has mentioned on more than one occasion that the engine upgrades (superchargers for the diesel engines) are not historically correct and will allow your boat to go faster than any historical one did.
As far as
when upgrades become available, I believe that these are accurately modelled in SHIII. This is where I see the good side of the "renown" system. I believe that it was either luck, or "knowing someone who knew someone" that allowed you to get the newest upgrades as they became available.

Not quite. From what I've read, Alberich was an experimental rubber type coating that they hoped would absorb some of the ASDIC signals, as well as insulating the inner noises of the U-boat. Only a few boats actually were treated with it (I just found one source that said less than 10 total) since it was found that the adhesive they used to secure it to the hull was flawed and pieces of the coating would come loose and flap as the boat traveled along submerged, actually creating more noise instead of dampening it. Later in the war, an improved adhesive was devised and all later boats built were to have it, but...well, we all know what happened in 1944 and 1945
