[PSUBS-MAILIST] Nuytco visit

[Private]

Heh, I'd emailed Hank off list offering the loan of an "auto surfacer" for his depth test. It's a device that blows your ballast when either a timer reaches it's setting or water is detected in the bilges. 

Best,

Alec

Dr Nuytten was kind enough to spend the better part of the morning showing me DW's and some mature subs as well.  I had a great time listening to fascinating stories and seeing how the big boys do things.

I would like a back up, some way for a timer to tell Gamma it is time to come home.  Any ideas would help, I have never tried putting a backup together.
