Diving times...........

Rockin Robbins · 09-12-07, 03:45 PM

Actually the American boat's slower dive time is a non-factor with radar. As long as you time the dive properly, it doesn't matter if dive time is 120 seconds. Modern boats take even longer to dive, at least the boomers do, from movies I watched on You Tube. German boats' dive time was a survival skill. It is not on the American sub.

Ducimus has made dive time about 45 seconds for Trigger Maru and I like that a lot better than stock.

I've read it was 50 seconds in WW2, coming from an ex Requin sailor.

You really have to qualify this when you discuss absolute times.

There is a book procedure for diving a boat, and then there is the "combat zone" procedure used by many of the experienced skippers and crews.

The former required, for example, a green board before any vents were opened, and other operational safety-first considerations.

The latter, on the other hand, included such irregularities as opening the vents while the conning tower hatch and the main induction were still open, and running on the surface, as a matter of course, with the negative tank already flooded... both of which would get you canned for sure during peace time.

But during war time.... that shaved the dive time (from dive order to sheers under) from 100 seconds or more to under 40, as I understand it.

I timed mine from Flank Speed To parascope level from the time I gave the order was 2 min 12 seconds.

Most of the books I have have them aiming (with US fleet boats) for under 40 seconds.

They did mid-30s most of the time on crash dives. Stock is too long. Not to mention the crew didn't have to run forward

Unfourtunatly the boats speed does not seem to effect diving times in the game.

In fact it has been revealed that the boat dives FASTER at a dead stop than at flank speed. :hmm:

I dont see that much difference and dive at flank anyhow, would rather have the manuvering speed available to me.
