Yep, new one on me too. Impressively whiffy entrance though:

What's a 'sprengboot' then? Google translates it as 'Busting Boat'........

Explosive (charge) boat.
Sprengstoff = dynamite.
Sprengen = to burst/ force. blow open.

Captain or crew of a "sprengboot" would not be a good long term career move.

Just shows Google Translate's spelling limitations.

What a cool looking beast ! Nice to see the kit, but it looks like it would be easy enough to scratch....

Ummmmmmm ...... Is that a pluse jet on the back like a V-1

?

It sure looks like a pulse jet- that is the first thing I thought of. Guess they won't be sneaking up on anyone with that ?

Wonder if the vanes on the bow push it under a ship and it drops a charge of some sort?

There's some (not too well) translated info at the bottom of this thread http://www.histomil.com/viewtopic.php?f=211&t=14265 - the engine was indeed an Argus-As-014 as used on the V-1, while the floats came from the Ju-52.

The "vanes" are the triggering device for the explosives. The idea was that as it approached it's target the crew locked the rudder and bailed out onto rafts. The boat kept on going and when it hit the hull side of the ship the bars set off an electrical trigger which exploded the explosives. The Italians had a similar system for their motorboats and the Germans for various other explosive boats they were developing as the war ended.

There is a different description how the "Tornado" works in this article. The floats were the explosive loaded devices and some 2000 meters before the target they had to be jettisoned and reach the target alone, just because of the initial inertia

. The crew had to return in the boat (or whatever remains from it

). Since only the floats were to be destroyed, the project wanted to save materials, not using expensive torpedoes.
I'm really not sure how the whole thing could work?

That is very interesting. I think I have everything in my stash to make one ... !!!!! I'm going to have to check into this .......

Something just occurred to me, just how did this boat go fast enough to make the pluse jet function

? Aircraft had to be launched by rocket or carried aloft. Hummmmmm.........

Do it ! It looks so cool on that boxtop

No, it would just need enough air flow to start the fuel burning process inside. Once ignited, the pulse frequency and flap mechanism keeps the process alive, unlike a ramjet engine that needs the high airflow speed. I just doubt somehow that a single Argus pulse engine would get that thing to decent speeds? I have read about bomb ships with an Argus on the back ("Wasserlinse", IIRC), but these were supposed to be small boats, reminiscent of speed boats?

As a side note: the kit appears to be pricey - found one from a German dealer. Not certain if photo etched parts justify more then EUR 30,-...

After checking out the links,I think I have everything I might need to do one. The only major problem I see is that all the drawings and photos are different in detail. In addition,there was to be a "command boat" included in the three boat kite or attack group. More to the point, that spring loaded frame is the first detonator and I'm not sure it would be found on the command boat

? One thing I am sure of is that this was duty for the politically incorrect .... !!!!! I've also found different descriptions of just how the attack worked,too. It seems that the crew were to jump out of the boat about 2000 m from the target and swim home or back to the command boat

? Another version had the crew section detach and go home under it's own power. There were several kinds of boats of this kind some unmanned others manned. More on this later after I dig in my spares box........
