I have personnaly dived in a 40 sits tourism sub-marine in monaco , the sub hull was totaly made in a transparent resin (very thick), so i see no reason why a sub could not be made in a plastic material.
---it is probably cast acrylic. As far as I know exists no clear resin.
Clear resins do exists , i use it very often to built housing for my diving électronics, of course I don't know if it could be used to buit a sub .
On the other hand i could note that this kind of building requires bigger means than the traditional stell hulls, it cant' be done in a small garage, requires big moults , amtmosphere control (humidity and temperature).
Steel or GRP; I think the same workshop space is required. but you dont wake up the neighburs with the angle grinder.
no in my opinion big construction in fiber glass require more space to store and use the big mobines of fiber , and also the tempreature and humidity must be controlled.
Personnaly i am really interrested in the result cause i would like to built an un motorized sub five meter long designed to welcome divers for 4 days with the possibility to reduce the pressure up to surface pressure at the end of stay.
--Do you have a drawing?(post to moki) what hull diameter. It schould have some comfort for a long deco stay.
the drawings are not yet postable but will be soon, the hull will be cylindric , 2 meter diameter and 5 meter long !!!!, it will be confortable enough to host 2 divers for 4 days,
we are at the time playing with a fuel cell , and won't begin construction until we have mastered this technology for we want to be independant from surface.
the energy needed will be used to power the co2 scrubber fans the deshumidification system and the ligth.
for the moment we have no solution for dehumidification , what do all of you do to avoid humidity ?
there will be no heating system and the life conditions will be simpflied as mutch as possible.
I have personnay spent 6 hours in a deco balloon at 6 meter and it gave me the idea of building a module permitting to enhance this time to a couple of days.
of course all breathing gases will be managed in close circuit .

or maybe am I a stupid newbie dreamer that has nothing to do here ??????
--No
