based on 1938 patent of German dentist from Berlin
build Prototype around 1941 and tested

after Author Richard Lakowski in "U-Boote Geheim". from HEEL-VERLAG (picture also)
the union of German sailors demanded life insurance of 100000 Reichsmark

A possible relative of the somewhat spurious "Submersible Tragflügelboot Projekt" described on http://www.german-navy.de/kriegsmarine/ships/fastattack/index.html ?

thank for link
but on page i found this
Another project based on Wendels initial small fast attack boat design, was a submergible hydrofoil. Equipped with a Schnorchel and periscope, the small vessel should have been able to set itself on the ground of the sea in shallow waters.

The operational pattern behind this idea was the following:
With a target approaching this position, the hydrofoil should surface by blowing its dive tanks and make a fast attack on the enemy ship. After that it should disengage at top speed.

There are not detailed technical data available, but it is almost certain that this project should have had a similar size, armament and performance than the other Wendel fast attack boat designs.

None of these vessels was ever build.
from Picture they build one vessel
and the grafic is wrong, with long Stern
you see cleary that Prototype has long bow!

"It appears to be a semi-submersible along the lines of the Confederate David spar-torpedo boats of the US Civil War."

And reading the reports, it even was similar dangerous for the own crew ...
On full power it was said to have a bank angle of about 15°

There are two pages about the boat in "Geschichte des deutschen U-Bootbaus", Band 1, by Eberhard Rössler - pp. 189f.

Much of what I read here seems to be 'inaccurate'.

The boat was proposed as an alternative to submarines if the efforts to immunize teh subs under water would fail.
It was meant to attack at the surface at night - conventional subs proved to be capable in this even despite their slow speed - and would survive due to being a small target and very small.

It was a project of 1937-1941 mostly, and was recognized as needing too many bucks for the bang.

Torque was a big problem, and the test boat was only 250 tons.
Production ships would have been 600 ton ships, probably with armored superstructures.


question: I could scan two pages (German language) and upload to imageshack, would that be OK?
Some forums are hyper-sensitive about this.

It was not meant to dive regularly, but to sink itself to the sea bottom for hiding - no underwater movement.
