When a warship is sailing, no matter how rough the wind and waves are, it will not capsize. What can keep the balance?

First of all, the length of the anchor chain must be greater than the water depth, but the water depth in the ocean far exceeds the length that the anchor chain can reach. The anchor chain of a large ocean-going ship is at most 300 meters long, which is nothing compared with the deep sea.

In order to keep balance in the deep sea, the ship must first keep power drifting. It's not reliable to stop, you must move, and the bow must break the wind and waves, otherwise it will be easily overturned by the wind and waves. What we are talking about is riding the wind and waves with this attitude, and we must bow against the waves.

At the same time, in order to improve the seaworthiness and seakeeping of ships, designers have designed various ship anti-rolling devices, which generally reduce the rolling of ships and avoid capsizing. The most common is the bilge (bi) keel, which is the cheapest and most cost-effective balancing device and can be seen on almost all ships.

On large ships, there is usually an active fin stabilizer at the front end of the stern keel, which can be telescopically hidden inside the hull or stretched out like a wing to fine-tune the ship's sway.

Unlike the calm offshore, the ocean surface is unpredictable, and there are often sudden waves. The swell in the deep sea is much bigger than that in the shallow sea. How do warships digest these forces and keep the hull on the water? You can't rely on collapse.

When a ship enters a port or offshore wharf, the crew will often put down the anchor chain and let it sink into the seabed to fix the ship. The anchor chain is very heavy. When it is inserted into the seabed to form friction, the ship can be offset by friction when it is shaken by wind and waves. But in deep sea, the anchor chain doesn't work.

Large ships generally have active anti-rolling tanks. Through these balanced components, the weight of the hull and reasonable handling, warships can sail safely in a long voyage. Thanks to the escort of these ship designers, if you fall into the sea while sailing in the ocean, you will really be scared to death instead of drowning.
