correct friend, the Allies called the boots E meaning enemy.

I think the whole concept of the German S-Boot being developed because of the Versaille treaty and what they did with them was quite awesome. To me they were great boats.
 
The E boat/S boot was definately the best of the WW2 small attack boats the MGB's MTB's and PT boats did not match the E boats in general sea kindlyness even JFK of PT 109 / the US president fame admitted that he thought them a far better boat on a vist to one in Germany.
 
There was a lot more designing and planning involved with the S-Boots. They were designed to be able to take on large ships at Sea but were small as limited by the Versaille Treaty. Quite genious actually there design.
 
I would have to look but the AA armament for the small boats were rather large, up to a single 4cm weapon. 2 torpedos later 4, with 2 rearward firing.

hope the next image works as it is the predesessor of the WW 2 type, from ebay.de

The S-Boats were superior in design to the MTB but I certainly wouldn't say "far superior" plus the Royal Navy developed a better system of MTB and MGB support.
Plus the MTB gave the German merchant vessels a lot of trouble in the North Sea, and little could be done about them.
 
I think the S-Boots were the best of there type. There were several similar types of boats that were very good and close to it but I think the S-Boots were a true example of great engineering adn thought.
 
Here is why the S-boots were better at sea than the MTBs - the Lurssen Effect

OK, basically, the center rudder did all the steering and behaved exactly like a normal single-rudder set up, so the S-boats were, in effect, single-rudder ships.

The two outboard rudders were 'trim rudders', designed not to assist with steering, but to affect the angle of the hull as it goes through the water.

At low speed, the two outer rudders would remain parallel to the line of travel. Once the vessel got up to about 25-26 knots, they would be turned outward, away from each other, until they were pointed 30-degrees out from the line of travel. This caused the water to be pushed ahead of them, instead of passing cleanly around them. Because this zone of water traveled along with the hull, the screws were kept in a zone of water that was moving more slowly past them than the actual speed of the ship. The propulsive force of the screws is increased, allowing them to push the vessel along at a slightly higher speed (about 1 knot) without increasing RPMs; basically, instead of spinning the screws faster to keep up with the water rushing by, you have slowed the water down to allow the screw to push against it at the same RPM.
The biggest benefit is that the stern of the vessel gots pushed upward, leveling the boat, which eliminates the 'rooster tail' stern-wave and also cuts down on drag. The rising stern forces the bow back down, and the 'white water' bow wave disappears. So now you are going 27 knots instead of 26, making less noise, and showing very little wake.

Of course, you want to go faster than 27 knots, but the drag of the trim rudders angled out 30 degrees prevents this. But here is the cool thing...once the Lürssen effect kicks in, you can slowly bring the trim rudders back towards the centerline as you increase speed, without disrupting the effect, until they are at just a 17-degree outward angle. Now the speed increase is on the order of 5%, so you can go 42-43 knots on the RPM for 40 knots, and you are still making very little 'white water' wake. So you have no white-water wake to betray your presence at night, and you are making less noise than you enemy...does it get any better for a night attack?

The Lurssen effect also gave better acceleration and the single centre rudder and two aerofoil shaped outer rudders gave better maneuvrability than the MTBs

Because the S boot was quite level even when speeding at sea, a Luftwaffe gun turret could be placed in the nose, with 360 rotation and 90 elevation without the bow of the Sboot pitching up and blocking the view like on MTBs

Well I know of one Cruiser the HMS Charybdis that was sunk by German torpedo boats. The rest of these are not capital ships but destroyers. But the Cruiser is a Capital Ship.
