1 meter per 20 seconds!?

applesthecat · 05-02-09, 11:49 PM

What is a normal descent/ascent rate for a type vii sub? I find that my sub goes up or down by about 1 meter every 20 seconds and perhaps only a little faster with blow tanks or crash dive.

Is this normal? The sub had a nose down attitude of only about 5 degree when descending. Also, is there a way to manually manipulate the dive planes, like on silent hunter I to dive faster?

I also found I could not rise with my engines off. Shouldn't blowing ballast rise the sub regardless of forward speed? Don't subs rise by positive buoyancy?

I had no damage to my dive planes.

Thanks
