RE: [PSUBS-MAILIST] Inflatible Lift Bag System on Sub

[Brent Hartwig <brenthartwig@hotmail.com>]

In another post, I mentioned a boda bag for wakeboarding boats. I've discovered they are now called fat sacs. Here is a link to an integrated bow fat sac made out of the same material as inflatable river rafts. I think it could be used as an inflatable lift bag inside a soft tank and/or externally for emergency flotation and/or surface stability. You would likely need large check valves on the sacs to let out air as you ascend from depth.

Did you guys see the 2 – 1,000 POUND EMERGENCY LIFT BAGS (1 FRONT & 1 REAR) installed on the Great Lake's Sub for sale on ebay? They are installed on the inside of the soft tanks.
