Boat people, how much does 990 feet of that chain weigh?

[BigV]

About a fuckton/foot, given the apparent scale of the picture. Wow.

I saw the chain on the USS Hornet carrier in Alameda a few years ago; best part of the tour.
This is the Ford, brand new; 136# links are "light weight technology":

And a nice rope, too:

I looked at another anchoring video which had some interesting comments.

What if anchor stuck in seabed .

If the anchor stuck in the sea bed and the ship is not able to draw it out, usually the chain is cut and a buoy marker is left attached to the other half of the chain which will go with the anchor so that it can be retrieved later.

I was a 3rd Mate back in the 80's and we all got told it is the weight of the WHOLE CHAIN that holds the ship from dragging , the anchor simply holds the chain in place.

That's correct

2 questions though... How much cable to be paid out for it to hold and how one will know that its actually holding but not drifting?

The anchor chain length will depend on the depth of anchoring point. The thumb rule is "Scope of 6" i.e. if the depth is 25 m, the anchor cable to be paid out 150m. The Ship should move in a fixed diameter and that should not change....however, in case of wind, there can be a small drag.

How do you de-anchor to release ship to run ? Or how do you release the ship from the seabed taking off the anchor?

The windlass or anchor winch is used to wind up the chain and lift the anchor. If the anchor is stuck, the ship is moved aft and ahead to release the anchor (which is unlikely as ships are anchored in dedicated anchor stations where such problems do not occur).

Aha, so that's why they need near 1,000 ft of chain.

Three years ago, I was on a small motor boat that anchored off the Florida Keys. The anchor got wedged under the lip of a large rock and moving around didn't release it. We could see it, since the water was only 15 feet deep or so. And so one of the guys dove down to release it.

Come think of it, we slept in that morning and got the boat captain nobody else wanted. He wasn't very good at putting the boat where he wanted it.
