Re: [PSUBS-MAILIST] American Sportsman Submersible
Hi Steven -
Vance is right - the twin Tower boat is even in my sources
the 300 version.. but Busby told that Brazosport owneds a 600
with a single tower..
May you can meassure (sounding) the hull tickness with a
magnetic indicator - most yards and bigger steel companys
have such a unit.
Take the measuring all 1 foot in all directions and label the
numbers with a pen direct on the spots on the hull.
Special attention to areas which are difficult to maintance
- like the bilge ara, hull to sidetank weld connections areas..
Vance can may better explain on which spots you have to take
the meassurings on this boat.
If the figures on some spots is differnt (smaller) than the
given one - be carefull - maybe it is nessesary to recalculate
the hull dive deep. If the hull tickness is still okay
a modern recalculation would also very helpfull..
Maybe you get more or less deep than the given figures -
note your calculation is over 40 years old and from
a unkown type ..
According to good shipbuilding practice - shell hull
should be replace if they lost more than 10 % of there
thickness..
Is the 8 inch diameter conical and 1 inch tickness
window of a flat or a dome type ? Is 8 inch the
inside clear view ?
Like this ? :
---------------I flat window I---------
----------------I 1 inch strong I----------
-----------------I 8inch here I----------
If this is true (flat type) it is according
to the GL Rules good for a dive deep just in the
40 m (130 feet) range ..
With a little raised 60° dome type good for about
450 m (1470 feet).. but need drawing for final cal..
Dive deep for 300 is given with :
operational workdeep : 90 m (295 feet)
collapse deep : 305 m (1000 feet)
hull tickness : 9,5 mm (37,4% of an inch) A36 steel
for the 600 is given with :
Op.workdeep : 185 m (607 feet)
collapse deep : 460 m (1509 feet)
hull tickness : 12,7 mm (1/2 inch) A36 steel
Some pictures of your sub would be very nice..
.. were do you live ?
