No - the called it just : the U-Boot

No.1 was never build because the Lorry with 
the material to delivery was burn down by sabotage. 

No.2 was also never final build because the
workshop was blown up by sabotage..

No.3 was secretly build and sucessful tested. 
It was later stolen.. but find later the way back
to Spirou - but the mainwaterpump for the drives
was destroyed by sabotage. Later this boat 
was destroyed by explosion (also sabotage..)

No.4 was build and tested and the only boat survived. 

No.5 was destroyed during construction by sabotage. 

No.6 has the same fate as No.5

I get the comics before starting work with Sgt.Peppers
and they give me some inspiration.  Special the prone position
and the small size. But Spirou's boat is a ambient wet boat.

In which way you want to navigate on the surface ?

I have exact this done. A flood vale (1 inch) on top with a rubber pipe
snorckel 
part inside and a very short extension outside. So I can brease on the
surface - 
to save oxygen and CO2 absorber run time and flood the boat on the
bottom if nessesary and let still the compressed air in. But maybe for a
flood vale a little to small - 1,5 to 2 inch would be better - flooding
time is a important factor in deeps greater 90 feet.. 

I just thinking that you will first drop your dropweight container
and for the reason of the graphity center after drop - a flood vale 
on the stern endcap make some sence. You can flood the boat - and leave 
after ambient pressure in the boat with the dome over your head as dry
bubble. 

The orignial idear of Sgt.Peppers was quite simillar - using the 
battery to trim the dome over the surface - secure the boats bow on the 
kai and go in and out this way. But was to expensive - so I did'nt build
the
moving trim battery .. But you can do the same with the snorckel vale 
- and a rubber pipe extension - maybe the better way because no need 
for a remote controlled - or foot controlled valve.

I have three lights - One spot beam light outside (50W), another flood
(wide angle) fixed beam light (50W) also outside. And also a hand held
movable spotlight (also 50 W) inside. To prevent reflexion it is in a
plastic cylinder casing - the front of the casing is about 2 inch longer
than the light and has a soft rubber (neopren) seal - so I can contact
it direct to the inside of the dome to prevent reflections. I use the
inside search light normaly just for
very short time to search for points outside the light area of the both
outside lights. So for this reason there is no heat problem. If I found
something intressting I switch the inside search light off and turn the
boat in that direction.  

You can make first some test with a strong pocketlamp. Maybe you catch 
reflections on the inside of the outside dome.. If not you can build in
the 
searchlight later in .. 

During the first dive and drives Sgt.Peppers has no top hatch. During
this time I need a radio remote voice control on the surface to find the
way home..  

"Submarine from Alpha Groundstation - turn 20 degree left for 1 minutes
than 45 degree right - awaiting final landing instruction" 

- funny for the visitor people around our Alpha station (a car with the
trailer) - not so much for me..   .. special not if children or boring
people found the VHF channel and give other commands or just make
nonsens. Later we make some secret commands to change the channel. And
now the sub has a top hatch.. 

But you can shift sometimes the battery aft and have a look..
