Subject: [PSUBS-MAILIST] Another semi submersible
Date: Thu, 10 Nov 2005 04:42:06 -0500
Here's another semi submersible that works on the same idea somewhat as the
yellow submarine link in my previous e mail below.
For those members who want to get underwater but don't want to worry about
ballast, tanks, buoyancy calculations, etc,
this is another one that would be safe to learn on before maybe later going
to a completely submersible sub. At only 40
inches underwater the pressure isn't too much to worry about.
I had a similiar idea of using 3 large tanks connected to each other with
pivoting booms and the middle tank would have viewports and
be weighted on the bottom and heavier than the other two tanks which would
act as buoyant surface pontoons while the middle one would
submerge and that would bring the two outer pontoon tanks together side by
side as buoyancy tanks on the surface that held the
third underwater tank's submerged weight, then blow third tank ballast to
be on the water surface level with and between the other two pontoon tanks.
Of course you would have a long stove pipe style hatch going all the way to
the surface so you could climb out of the submerged
middle tank hull to the surface whenever you wanted. So although the third
tank in my idea would be submerged, there would be a
chimney so to speak always going above to the surface. I would make the
pivoting booms so when the middle tank was submerged
the "chimney hatch" would always protrude above the water line and have a
small freeboard decking around it also.
With a large enough tank and enough weight to take her under, my 3 tank
semi sub would make a nice underwater lounging cabin. Not a true sub but
not bad either! Imagine you and your cabin mate looking thru the portholes
with lights installed outside and then hopping up the chimney ladder to the
surface
to catch the sunset over the ocean and then spending the night below in
your portholed submerged cabin. Can you see it? Engines could be in the
topmost
pontoons or the submerged one. Snorkel to the surface would supply engine
air if engine in submered tank. Possibilities.
This fellow has used a similiar principle but with a smaller cabin.....

Subject: [PSUBS-MAILIST] Who makes this semi submersible?
I found this every interesting semi submersible at Nautical Niche at
this link.... http://www.nauticalniche.com/undersea/yellowsubmarine.htm
I tried to find out more about it but there doesn't seem to be anything
else about it on the net. Does anyone here know who manufacturers it?
Is it made by nautical niche or someone else? I e mailed nautical niche
but no answer yet.
Even though the upper hull never submerges, doesn't she just scream out
to have someone make
this design into an ambient sub? I get ideas just from looking at her.
Imagine if she could be converted to be an ambient sub and then you could
have enough room at the top for 4 people or lots of room for two people
on the surface, then just take her down shallow for a two person ride.
Modifications would have to be made first of course. Makes one think
though doesn't it? A boat AND a almost pre made ambient?
If anyone knows more about this semi sub boat please let me know.
Thanks,
Bill.
