Schnellboot Type S-38
Italeri

E-boat was the Western Allies' designation for the fast attack craft (German: Schnellboot, or S-Boot, meaning "fast boat" ) of the Kriegsmarine during World War II. The most popular, the S-100 class, were very seaworthy, heavily armed, and fast – capable of sustaining 43.5 knots (80.6 km/h; 50.1 mph) and briefly accelerating to 48 knots (89 km/h; 55 mph).

These craft were 35 metres (114' 10" ) long and 5.1 metres (16' 9"') in beam. Their diesel engine propulsion had substantially longer range (approximately 700 nautical miles) than the gasoline-fueled American PT boat and the generally similar British Motor Torpedo Boat (MTB).

As a result, the Royal Navy later developed better matched versions of MTB's using the Fairmile 'D' hull design.
