In the US there is a tendency to sue for anything.yes
In EU less, more because the same suit would take decades before it gets
finished but
basically it is the same laws but access to the courts in the US is much
easier.
In France it took me 7 years to win against a manufacturer

This is true.

this is true

So what ? If - your - sign is under all drawings of CSSX - and I build

depends of the cause of the explosion:
if you installed a non ignition proof electric device in your sub, you are
responsible, not the manufacturers  of the tanks of H and O2. in that case
a spark can ignate residual gases around
if H tanks ruptures, manufacturer is responsible. Storage of H2 is strickly
regulated, if something hapens because in the chain of design something was
overlooked, the one who failed to comply with existing regulations will be
responsible.
If a battery box collapses and somebody gets hurts because of chlorine gas
due to sea water and acid mixed, the manufacturer of the battery box is
responsible, not the battery manufacturer.
If someone drawns because the emergency hatch is stuck, the manufacturer of
the hatch is responsible.
most of the time if parts and equipment installed in a submarine are already
certified and are put to work within their specifications, the manufacturer
of these equipment will not be responsible. It is true that they will be
sued anyways but claims will be dismissed.
The designer who puts together all these equipment must verify that nothing
can go wrong.
if something can go wrong , it will (Murphy).
Now if you realease volontarly  in the atmosphere propane or H , and if
somebody gets hurt you will go to prison, US or EU. Tanks manufacturer is
not responsible for the use of its equipment.
It is most likely the builder of the sub to be liable in case of accident,
not the manufacturer of parts and equipment.
The user is liable if he operates the sub beyond the specifications or if he
fails to maintain his sub.
Sometimes people forget that USCG inspections are not to restrict
manufacturers but to ensure that users keep their vessel in compliance with
manufacturer specs. otherwise
users to save money would skip battery or tank replacements.


Through the remarkable design of your sub, I can see the time and the money
you put in your work , probably reviewing 1,000 times all safety factors and
failure simulations.
But I have also seen passionate psubers that are forgotting basic rules in
order to build cheap or sell a sub  and achieve their dreams.

A submarine is a life support vehicle, caution is a must and liability is
the guarantee that keeps off hazardous designs.
All manufacturers carry liability insurance, when a design is approved to my
experience it costs about $500 per mini sub or  rebreather.
a liability insurance covers you in case of a law suit, but it doesnt mean
you are going to loose.
In the us they sue you for burning your tongue in a coffe cup, imagine the
explosion of H in a marina !!
I agree that you are responsible for what you sign the point is that
plaintif will chalenge the understanding of user in order to sue ALSO the
manufacturer. The buyer alone is responsible only if he made a mistake. for
instance
There is a doctor here in miami he got 50 years in prison for a collision
with his speed boat, he killed 6 people, he was drung at the helm at 60 mile
per hour! he got what he deserved, you just cant harm others without
impunity. The boat manufacturer was sued as well, but case was dismissed.
