- The Schnellboot, or S-Boot (meaning "fast boat") represents a class of fast attack craft employed by the German Kriegsmarine during the Second World War.
The main wartime production boats, from S26 onwards (but often designated the S100 class), were very seaworthy, heavily armed and capable of sustaining 43.5 knots and could travel at up to 48 knots for short periods. These boats were armed with torpedoes and Flak guns; typically one 37mm at the stern, one 20mm at the bow with a twin mount amidships, plus machine guns. Armament varied and some S26 class boats substituted a 40mm Bofors or, less commonly, a 20mm flakvierling quad mount for the aft 37mm cannon.
The S26 class boats - which provided the bulk of the wartime deliveries - were 34.94 m long and 5.38 m in beam. Their diesel engines provided a range of 700 to 750 nmi, substantially greater than the gasoline-fueled American PT boats and British motor torpedo boats.
As a result of early war experience of combat against the fast and powerful S-boats, the Royal Navy created its MGB force and later developed better-matched MTBs, using the Fairmile 'D' hull design.
The design of the S-boot was tailored to the expected theater of operations being the North Sea, English Channel and the Western Approaches. The requirement for good performance in rough seas dictated the use of a round-bottomed displacement hull rather than the flat-bottomed planing hull that was more usual for small, high-speed boats. The shipbuilding company Lürssen at Vegesack, Bremen, overcame many of the disadvantages of such a hull and, with the private motor yacht Oheka II in 1926, produced a craft that was fast, strong and seaworthy. It was also extremely seaworthy and very light, being constructed of wooden planking over alloy frames. This attracted the interest of the Reichsmarine, which in November 1929 ordered a similar boat but fitted with two torpedo tubes. This became the S1, and was the basis for all subsequent Schnellboote.
After experimenting with the S1, the Germans made several improvements to the design. Small rudders added on either side of the main rudder could be angled outboard to 30 degrees, creating at high speed what is known as the Lürssen Effect. This drew in an "air pocket slightly behind the three propellers, increasing their efficiency, reducing the stern wave and keeping the boat at a nearly horizontal attitude". This was an important innovation as the horizontal attitude lifted the stern, allowing even greater speed, and the reduced stern wave made Schnellboote harder to see, especially at night. The rounded wood planking hull helped reduce weight, and flattened at the stern area, the aft section area was reduced at high speeds, it allowed more hydrodynamic lift.

Stunning footage. Just seeing the amazing construction technique of these boats was something else. But the amount of labour involved, in building that latticework of the outer hull supports, let alone sanding down the hull planks? That's just amazing to watch. The workmanship involved in building these boats was incredible. I think this footage alone earns you some more coffees! Enjoy!
That was very schnell of you, thank you very much :D
@@hw97karbine 😂 Smooth...
Agreed. The man-hours involved there! It would be interesting to see an equivalent for a PT boat or MTB. Edit The IWM film ADM 5022 on the Fairmile for example shows a similar hand-built approach.
Our PT boats were also made from wood with LOTS of hands on wood working ! I love these Boats these Schneel boats are the best and 1 reason for that is the much safer Diesel engines !
My favourite boat! Thank you for sharing this!
great video, what a beauty, thank you for uploading!
Wunderbar! Danke'.
I love these little boats, the most fun I ever had in War Thunder Naval battles was when I used take one of these, sneak up on a battleship or dreadnought, and send 2 torpedoes into its hull hopefully hitting a turret or something else that explodes, all while listened to Das Schnellbootlied on repeat.
Woah, whatever they are using to drill that hole next to what looks like the prop shaft is super cool. I assumed you would use an electric motor or an overhead belt drive on the implement itself, but the fact it's remotly shaft driven with a differential is super cool. And I assume that shaft is telescoping and leads to one of those two for power. I'm into vintage machinery, and I can't belive I havn't seen more examples of PTO like linkages.
Jesteś gospodarzem wspaniałego kanału! Jak Ty to wynajdujesz ? Dziękuję za pracę! A ten film - palce lizać! Serdecznie pozdrawiam!
Operating at night in littoral waters - these things gave the Allies fits.
Whoa i thought they were Made from metal sheets
Talented more back then also better working conditions as I restore large cruiser Yacht’s they actually do have better conditions lol
Very labour intensive!
Yes but a labor of Love ! lol !
Только немец поймет,как красиво и слаженно работает немец.
Kevin Wheatcroft owns the last surviving Schnellboot and he is going to begin restoring her in earnest later this summer, should he get all the permits he needs.
A pesar de la censura
The difference between a schnellboot and a PT boat?
PT boats burn easier.
who enjoyed watching slave labour quite a few judging by the comments shame on you glorifying war
