Torpedo net

Torpedo nets were nets made of steel rings that were in the form of a crinoline around the lying still warships, especially battleships and armored cruisers, hung to protect the hull from contact by torpedoes.

On moving ships, the torpedo nets were not deployed because the flow nets would then lifted to the surface and they would have been dragged. Since the explosion of the torpedo is only harmful when it takes place closer than about 3-6 meters from the ship, they had fixed the torpedo nets at the ends of a number of horizontally from the hull protruding and about 4-7 meters long spars ( sticks), so to be about 6 feet deep vertically hung in the water. In this case, a torpedo old design would be ineffective depend on the torpedo protection net.

During the naval battles of the First World War, it was found that the torpedo nets when they were shredded by shrapnel, as far as hung into the water and dragged the ship were that there was a danger that the networks fell into the propeller and these blocked. To avoid the risk that a ship is thereby unable to maneuver, renounced the Imperial Navy after the Battle of Jutland on these networks and let them expand on all ships.
