The anchor cable (chain) plays the primary role in holding a ship at anchor. The mass of the cable and the catenary between the outer end of the cable and the ship offsets the mass of the ship and the dynamic forces acting on it. The anchor serves to hold the furthest outboard end of the cable in place. Direct pull on the anchor only normally occurs when the ship is weighing anchor, and immediately after the anchor is dropped and the ship backs away. At least that's how I learned it during my training in the Royal Navy.

That inner piece on each chain link is a British patent/invention from the early 1800s. It stops the chain link from getting caught inside another link, thus fouling the chain.

That inner piece is the stud. Sometimes it is a separate forging that is inserted into the link whilst the link is hot, which then shrinks as it cools to grip the stud tightly. Sometime it is also then welded in for extra security. Some chain lengths have the stud forged into the parent material of the link. The chains made in Boston naval yard were usually like this, as were the chains made from Suel Taylors or Griffin Woodhouse in England, possibly other chain makers as well produced integral stud chain.

It’s not an anchor wind-lass, it’s a capstan. A windlass has a horizontal main shaft and cable drum (think of a boat trailer which), a capstan has a vertical main shaft and cable drum (as shown in the video). In the case of ship anchors, the drum is a wildcat with proper grooves to engage the anchor chain and draw it in.

@@christophermarshall5765 Then it was written WRONG!!!!! Capstans and Windlasses basically do the same job but they do have different names depending on whether they operate vertical or horizontally.. But the biggest difference between a capstan and a windlass is that a capstan has a smooth drum and is for moving rope only, while a windlass has a gypsy (teeth) that interlock with the anchor chain. Sometimes there is a drum next to the gypsy on the same shaft that handles rope. It's still a windlass.

Great video, especially the second half about floating wind turbines. There is a small error in the script however that mistakes Megawatts for milliwatts. It's a factor of a billion, but, who's counting...

Never been around the 60K lb anchors (and 350 lb links) of a Nimitz class carrier, the biggest I've seen used was the 40K lb anchor and 155 lb links on the USS Essex LHD-2, they are still HUGE though!

Great engineering when they can create big things!

While showing painting of the anchors, you never mentioned why some anchors are painted gold, while others are gray. A gold anchor is awarded to a ship that has a high retention and re-enlistment rate.

Do anchors ever get stuck? And if they do, how do they unstuck them?

Would slip over and watch the anchor chain for Forestall being forged at Charlestown navy yard in 1955, only a few were put on flatcars at a time due too weight and size.

I was stationed on the U.S.S . Orian AS18, submarine tender, we were coming back from a cruise from a port in Spain, they medmored the ship, tied the bow on to bouy's , and tied the stern, to the pier, when they were dropping the starboard anchor chain, they lost brackes on the winch system, and the anchor chain went in the ocean, it made a whole lot of niose when it dropped

Still working on that ship in Newport ShipYard.

There is a faulty explanation about the anchors, the anchor and the weight of the chains gives that stability. The anchor mostly doesn't engrave itself, it's just laying on the sea bottom. Depending on the sea bottom, if the anchor engrave itself, it would be very dangerous to bringing it back up, because it would pull the ship downwards.
