About periscope up speed damage

Playing Dangerous Waters there is a limit (I think 5-8 kts) that the periscope can be raised while submerged/surfaced without suffering damage. SH 4 or other SH do not have this feature. If this is the real thing on WWII boats as well can we modify some files to simulate this?

Well modern subs can go way faster than 8 knots when submerged so there is a need for an speed limit to raise the periscope.
Fleet Boats and U-Boats couldn't go faster than 8 knots while submerged so there is no need for such a limitation.

On the other hand there is anecdotal evidence that raising the periscope at more than 3 knots would cause enough vibration to render the image unviewable.

I got damage at 8 kts in DW or a bit faster so I thought raising the scope while submerged at 9kts in a Balao would do damage as well....I was just curious as if in a real WWII boat they would go from ahead full to 1/3 submerged to prevent damage to the scope.

As I said, it's my understanding that damage wasn't the problem so much as not being able to see anything due to vibration. That said, I really don't know the exact parameters and problems.

I always slow down to use the periscopes, but that may just be me.

Yep. That's common sense. I'd do that too.
