[PSUBS-MAILIST] G.L. Submersible Classification

Wed Nov 27 14:07:08 EST 2013

My thoughts for going through the G.L. classification pdf
is to build as close as possible to certification standard.
I won't be certifying the build I'm starting.
I may abandon some of their requirements, but at least I'll know what
these are. 
   I could go ahead with my build & buy all my electronic communication
equipment & life support etc, & find that if I'd payed a few bucks more or
made the right choices I would be compliant & could say I conform to 
classification standards. This may be helpful when dealing with authorities
at a later date, or selling the sub.
Cheers Alan

Thank you Carsten, I appreciate your input. It seems that certification is such a chore (and comes at such a high cost) that it probably isn't worth doing for a recreational submersible.   

I think Hank really nailed it on the head about testing. Proper testing builds confidence in everyone's minds. But to those who are willing to go forward with the arduous and costly certification process, I salute you. ~ Douglas S.

Assuming I am building a single (as in, quantity: 1) submersible that I don't plan to sell or give to anyone else, what is the big advantage/motivation to having my sub classed by any of these organizations (excluding the prestige)? That's a lot of money to throw at a certificate or whatever (that could be used to build a submarine!).

Patent’ – dirt  cheap, and protects you for 12 months or so )
