Alec, Are you venting the saddle tanks with a valve on the conning tower like the for and aft tanks?
Please post some pictures.

The saddles are about to go in the water for the first time, so I’m not sure I have a standard procedure yet, but yes, that’s how I was thinking they would operate. I’ve eliminated the VBT and will be riding a bubble all the time, so I expect it to be easiest if I use the saddle tanks for the bubble. Of course if there’s a trim issue, one can blow a little into the standard tanks too. But saddles will be the primary means barring exceptions with the trim.

AS: I’m aiming for neutral buoyancy, and the way you know you’re there is by the waterline. When the surface touches the apex of a K250 dome, you shut off the valves. This is also a reason for the tiny viewports on the top of a steel hatch, they’re not just for looking out of but for knowing when to stop flooding your tanks.
Alec, is your procedure to firstfully flood the MBT's (at which point you're still positive), then achieve neutral buoyancy by partially flooding your saddles?
