Hi P-subs.
Can someone please give me a steer on acrylic hatch
suppliers. I am wanting to build / design a 2 man twin hatch, saltwater,
1 atmosphere, 250 ft depth sub. I live in New Zealand. So don’t have
the access to suppliers easily.
So far I have spent about 2 months on design and have found
the forum great. Had to change the design a couple of times after getting
PVHO, and some of the requirements of ABS.
The worst one was the 30” from water level to hatch
opening. I cant go very far until I have a supplier for the acrylic
dome. Was wanting a 30” OD flanged design and have emailed various
People to find out where I can buy 2 domes but had no
responses. Tried Reynolds, Cadillac and some others. I would prefer to
get an existing mould design and thickness and this will then dictate the rest
of the hull options I can use.
I have bought K-350 plans and Stachiws acrylic handbook
to help me understand what works but I am at a standstill til I sort out
the Domes. So far the weight is about 5200 lbs and I am struggling to get the
weight down.
I want it to be easily trailerable inclusive of a docking
vessel and max weight for towing by car is 3.5 tons including trailer.
Another question is has anyone done a sub in Stainless steel?
Best regards,
Hugh Fulton
