Brian, I meant to say the K-250 boats generally have short VBT just under the pilots seat, inside. But some like the Great White K-250 have removed them so they can have two people inside. I still don't know exactly what they replaced it with. I'll have to ask Greg Cottrell, or Scott Cassell.

Hi Brian, The K boats generally have a short VBT just under the pilots seat. You might also consider using a bladder type that you can let water into with a valve, and then either just dump it out when at the surface, or better yet have a high pressure electric pump that can empty it for you at depth. Another version of this is a box tank, like was used in the S101 that you operate just like the bladder with a pump. The box tank can not take internal or external pressure, it is just a holding tank. Here is a drawing of the S101. The holding tank is just behind the conning tower, and taking up the lower half of the hull.

Hi All,
I'm contemplating puting a hard ballast tank inside my pressure hull. Do any of the Kittridge subs have this same set up ?
