Wie hält ein kleiner Anker dieses gigantische Schiff fest?

How does an anchor hold a ship that weighs as much as a city? A container ship weighs two hundred thousand tons—as much as a medium-sized town made of steel. It's held by a piece of iron that weighs less than thirty tons. The trick isn't the weight. An anchor holds because it digs into the seabed like a plow—and because the chain, which is heavier than the anchor itself, distributes the pull along the bottom. Even more surprising: The size of the anchor isn't calculated based on the ship's mass, but rather on the wind that presses down on its superstructure. ... This video explains: why an anchor holds by digging in, not by its weight how the anchor chain acts as a catenary and a spring, keeping the pull horizontal why the equipment ratio is calculated from displacement and windage area – and why mass plays almost no role which weak points are built into the system and why the seabed always gives way first what happens on deck when the chain is running – and what the "bitter end" is why an anchor is not a brake and cannot stop a moving ship how dragging anchors have severed gas pipelines and data cables where the limits of anchoring lie: poor seabed conditions, great depths, protected seagrass meadows One of the oldest inventions in seafaring – and one of the most thoroughly misunderstood.
