[PSUBS-MAILIST] PSUBS in Islamorada FL

[Private via Personal_Submersibles]

Hi Hank,

The MBTs are flooded at the
same time. I wouldn't say the pitch forward is sudden though. I know it isn't a free surfaces issue, because it's lots of small tanks. We're thinking of restricting the lines from the forward tanks.

Best,

Alec

Shackleton has an issue that I will be trying to resolve doing canal tests, making use of the calm water, davits, and brain trust on hand. I suspect the issue is that some tanks are flooding faster than others. She takes a nose dive on submerging. I'm not sure the issue will be resolved, but the test location and friends on hand make it worth the trip. R300 will be there and is all systems go, but Cliff's challenge will most likely be habitability given the temperatures, so he'll try to do tows and transits submerged just to keep the cabin conditions manageable.
