Excellent progress on Kreideseesub (what does this name translate into in English)! Nice design. Can you tell us some design specifications. I can't read German but it looks like the design depth is 250 km. Is this correct. With the design being for 2 or 3 persons, how are you going to handle the ballast difference between 1, 2 or 3 persons, +/- 70 kg per person, i.e., removable fixed ballast or extra large variable ballast tank? What is the hull made out of? Are you going to design for extended dives with CO2 scrubbing and O2 makeup? What is the main propulsion bus voltage? Are you planning on classing the boat? How do you plan to launch and retrieve the boat? What is the displacement and reserve of buoyancy?

Keep up the pictures.

Cliff

Hi,

The last 2 week I did 90% of Kreideseesub hull.

A professional welder did the welding.
