Linsen: One-man explosive-boat. Always employed in a team of 3, 2 explosive-boats and one command boat. The explosive boats each had 1 pilot, the command boat (without any explosives) had a pilot and and a team leader. They were 5.75 metres in length and 1.75 metres in width with a 3.6 litre Ford V8 petrol engine producing 95hp. They had a maximum speed of 32 nautical miles per hour with a range of 12 nautical miles. In operation the command boat led with the 2 explosive boats closely following staggering from port to starboard. The explosive boats are then piloted within decent range of the target with the pilot jumping off safely and the boat remotly controlled the remainder of the way from the command boat by a Goliath device. As it hits the target the front hull ruptures, the engine sinks with the aft section and the 300kg explosive. The explosive is detonated 2.5 to 7 seconds after depending on the setting. The Command boat picked up the pilot of the explosive boat.
