[PSUBS-MAILIST] G.L. Submersible Classification

Douglas, there is no advantage to class a such sub.
 
Classification is required if you like to insurance the 
boat or do commercial operations with payed crew or pay-guest.  

If I ride with guest or even own crew - the have to undersign a paper that they 
known that the boat has no insurance, and they take a risk on there own responsibility. 

A other good reason for certification is if you like later to sale the boat. 
A boat with a certification can be use commercial and get there fore a much higher price. 

A other reason can be maybe that you are unsure what you are doing. 
But in that case you should not build a Psub anyway.. 

A good compromice for Psub builder is maybe to collect all material 
certificates, building documentaion, construction pictures and test etc etc. 
and build the boat strait according to the rules. 
This gives you a chance to certificate the boat later. 

Nemo100  boats for example have a hull only certificate from GL 
and a saftey building certificate from Swizz Lloyds
and the insurance company / flag state accept that.

I have a question. 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!). 


If you plan to carry passengers for hire and need insurance, or are trying to procure commercial work of any sort, I understand completly. But for the average joe submersible builder, what's the big draw? ~ Douglas S.

RE: cost of sub certification - If you do all the test documentation, plan approval docs, FEA’s, Von Mises, construction drawings, electronic schematics, piping diagrams and sub-system drawings, yourself – figure about $50,000.

BTW, putting a patentable idea out in the ‘public domain’ most certainly doesn’t safeguard against anyone copying it – in fact, it may well be the exact opposite! ‘Public Disclosure’ may well prohibit the ability to engage the patent  process, period. (Not trying to chuck cold water, but check the US patent act and that’s what you’ll find . . . if you intend to disclose prior to patenting, then at least apply for a ‘Provisional Patent’ – dirt  cheap, and protects you for 12 months or so )

Hi Jon,
someone may have more knowledge on this but I think that
because you have put your idea out in the public domain
it may be regarded as "prior art work" safe guarding you against
anybody patenting your idea.
Can anybody have a guess at what classification for a boat similar
to a K350 would cost in fees to an agency, aside from all the additional
costs in getting together all the documentation etc.

And nobody better steal my idea until I patent it.
