Thanks Jon & hi Brian,
Brian, the hull is similar to Graham Hawkes
"Aviator" wich was made out of cast aluminum.
I'm trying to make this as small as possible so
that I have the convenience of launching it off
the beach etc. The shape is too complex for me to
make out of steel.
I'm designing this using a simple pressure program
& a large block of polystyrene that I've carved out
to fit me & the subs internal componentry. once
finalized I can contour the polystyrene exterior to within
.5" of the interior & just fiberglass over the
outside.
The small dimentions make it more suitable for
using fiberglass. Mostly I'll be about .5" thick (apart from
reinforcements)
& this will give me a 1000 ft crush depth for
an operating depth of about 250ft. However this will be confirmed
once my final design is analyzed. The composite
engineering program will also come up with a laminate lay up plan.
Regards Alan
