      Reason for 2 ore more anchors is mostly to have at least 1 spare!
      As mentioned in the video, the heavy aircraft carrier would have stayed in place in most cases even with say a 0,1 ton anchor if the chain was right lenght and dimension-weight. 😉 Becouse if they for example used a 1000 ton anchor and almost weightless steel rope,,
      the anchor probably would move every time the waves lifts the ship enough to STRAIGHTEN the rope!!!!!!
      For example my 35 feet fishing boat 18 tons have only a 40 kg anchor and no chain becouse i have no anchor winch, and use the net puller to pull it in. so i use led rope and add a 50 kg weight ore 2 + on the rope half way if the weather forcast is bad and i have to anchor instead of going to a safe harbour with wave brakes where i tie the boat to a dock

      Here is an example of the modern bigger hurtigruten even with side trusdters:::
      it still use 1 anchor for safety in harbour.. I cind of doubt even a carrier use anchors to turn in open sea, hehe

    Pulling all EIGHT anchors from the semi submersible oil rig on moving day is one hell of a party along with the rollback anchor "boat" that assists with their winches and our crane aboard the rig. The more anchors are pulled, the less steady the rig/crane are when crawling up onto the anchors once on the boat deck to pull the many pound shackles while knowing what swells will make the anchor taught on the line with the movement of the boat AND the crane lines from WAAAAAYYY up there is a dance for sure

    The weight of the chain and/or anchor plays a very small role... Think of it VS the weight of the ship!
    Chain weight and mostly length is so the anchor pull is parallel to the surface movement, letting the anchor work.
    The length of chain also plays a big role through mechanical resistance of each link, preventing motion/waves to get all the way to the anchor.

  • @okshooter2710
    @okshooter2710 11 месяцев назад +5

    First statements are completely wrong. It's the anchor and scope, scope, scope. Literally the length of the anchor chain or rope tied to the anchor. (In sufficient wind, the chain become bar-tight, just like a rope would.)

    No the angle of the chain helps set the anchor and help keep it holding. The 5-7 times in length is called the anchor's "scope". Yes if it weren't for the chain the anchor wouldn't hold, but without the anchor the chain will not hold the ship on it's own. The chain doesn't really provide holding power itself, it only facilitates it though geometry.

  • @lorenwilson8128
    @lorenwilson8128 11 месяцев назад +11

    Wrong - the length of chain laid out is to keep the force on the anchor parallel to the seabed. If you try to anchor with a rope or a short chain, when the ship pulls on the anchor, it pulls in an upward direction and the anchor comes out. The heavy chain lays along the bottom and changes that upward force into a horizontal force and the anchor does not pull out. This is why ships put out more chain when the wind blows harder.

    • @ralfsxm851

    Sail driven ships, used to move the ship by putting the anchor on a long boat.
    Row the long boats with the anchor out in front of the ship. At a point about 100 yards in front the long boat crew would drop the anchor.
    After dropping the anchor 100 yards in front of the ship. Once the anchor hits the bottom, then the ship crew pulls into the ship.
    The process of pulling the ship forward. Once the ship moves over the anchor, the anchor is placed back in the long boat, and the process starts over.

  • @Purple_Pixel
    @Purple_Pixel 11 месяцев назад +1

    Wrong, the weight of the chain helps avoid chafe on an anchor line against the bottom, the weight also acts as a spring in waves when the boat is forced back by a wave, and finally, the weight of the chain can increase the horizontal pull on the anchor and increase the likelihood the flukes on the anchor dig into the soft bottom. It does not however cause any resistance.

One bulk carrier, Chinese IIRC, steered across the Great Barrier Reef off Australia's east coast about a decade ago, tearing a huge gash across the reef.

      @@cvanscho the anchor is to help pull out the chain correctly out and make sure it stay correctly on the sea bottom. they do that while the ship is backing up. the weight and friction of the chain, is holding the ship in place, it also act as an spring.
      one thing they do when drooping the anchor, is that they first droop the anchor to the sea bottom with some slack on the chain. Then they stop drooping chain, so they can pull on the anchor, so it flips over and dig in, to hold the chain in place, first then they droop rest of the chain, while backing up.
      for example, an 60 ton anchor, as on US aircraft carriers, can't hold the 100.000 ton aircraft carrier in place. A single link on a anchor chain for an aircraft carrier can weight up to 360 lb (164kg), and you have around 1500-1800 foot of chain

    The anchor digs into the seabed and is moved around as the ship drifts on the surface, dragging the chain and causing 'broomstick-like' abrasions, killing off marine species and releasing carbon stores from the sediment. This has far-reaching implications for already stressed ecosystems and carbon cycling.
