Can someone give me some pro's and con's for having VBT's either inside, or outside of the hull? (besides the obvious fact that if it's outside, there's more room inside.)

Also, about using small VBT's in specific locations to provide normal trim, or for purposefull offset trim. Has anyone done this? Does anyone recommend it?

Thirdly....
If a diver leaves the sub via diver lock-out...the sub has just lost that person's bodyweight in ballast. Any comments on my idea of using a VBT which has been carefully measured and marked on the outside, with some type of magnetic float on the inside, running along a vertical composite track so as not to stick to the side of the VBT, which moves a marker on the outside of the VBT so that you can take on a *specific* weight in water, possibly to negate the effects of a diver leaving the sub.

Thanks to any replies,

Ken
