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

I'm currently reading Wahoo by RAdm Richard O'Kane and it seems like 40 seconds seems to be the average dive time. draw you own conclusions.

That being said. US boats were bigger than the german boats. Displacement of a Gato is 1526 (surfaced)/ 2424 (submerged) were a Type VIIC is 769 (surfaced) and 871 (submerged) both are in Tons (imp.) Think about this for a second the Gato has to take on 1000 extra tons to get under water and the Uboat and extra 100. Whats going to take longer?

Some other things that would help a Uboat get under quicker is the placement of the dive planes. With the american boat they are place about half way up on the hull when extended so there is no immediate use from them until the can get into the water enough to bite and help draw the boat under. The Uboat on the other hand had the dive planes on the bottom of the hull, providing an immediate benifit of helping pull the boat down.

All this being said the dive times in SH4 are a little off. I belive 1.3 stock a sub adrift will dive faster than a sub going flank speed ahead.
