Regarding "Dive Time"

Graf Paper · 10-21-08, 03:29 PM

Using the Type VII boats as an example...

The dive time given is defined as the average number of seconds, at a speed of 10 knots, that it takes for a fully surfaced u-boat (running at a keel depth of ~5 meters for the Type VII) to completely submerge once dive procedures are initiated, in optimal conditions.

A u-boat is considered completely submerged once the conning tower (turm) no longer breaks water and the keel passes a depth of 10 meters (the height of the Type VII from keel to bridge being about 9.6 meters.).

So the dive time, measured in seconds, is how long it takes during a normal dive to achieve a depth of 10 meters running at 10 knots in speed.
