Can you tell a little about the sub? knots surfaced/submerged, diving mechanism,max depht etc.

I am a bit fascinated by this stuff, its been a childhood dream of mine to build something like that, but i guess money would be a partypooper lol.

Sure, ill tell you what I know.

Kraka is a diesel/electric sub with a snorkel. The snorkel design is actully a ripoff from the german WWII subs.

Shes 12,6 meters long, can reach speeds of 7 knots on the surface and 4 knots submerged..

She has 4 balasttanks. 2 forward and 2 at the stern.
She has forward diveplanes, but none at the back.

She has an onboard compresor, so when the diesel in running she can build up compressed air for diving.

Max depth is about 20 meters.

At the bottom she has a diving hatch so divers can enter at exit the sub even if its submerged.

She has a digital periscope, as you can see in some of the videos.
