I used to work for a company that set mooring anchors in harbors in New England. We would set 4000 pound cement blocks with anywhere from 100 to 300 feet of chain. While the scale was obviously much smaller, the physics was the same. if the chain got going off the deck of the boat it would pick up speed and basically hop, slinging coils of chain, breaking things and generally being scary as hell. The only thing you could do once it got going was to get behind it and wait. I can’t imagine what it must be like to watch the size tackle that is shown in the videos live and in person. Cool videos, thanks for sharing!

Well I’m sure nothing can go wrong there right? ;)

OK, what’s happening in these videos?

Is the water too deep for the chain, or is the winch/brake broken?

Winch brake broke on the first one. Second one I’m not sure might be same issue or too deep?

I think in the second one the chain got hung and they let up on the brake too much trying to free it. Once it gets going there is no way to stop it.

I believe you are correct

I don’t deal specifically with anchoring and mooring gear but in talking with coworkers, basically the anchor brakes they use are already enormous, but are really borderline on providing enough dynamic friction to slow down/stop the anchor chain. In other words theres a terminal anchor velocity that, if exceeded, the brake will not be able to stop it.

I work at a marine engineering/naval architecture firm and we watch these from time to time for kicks. Basically, as I mentioned to McMike, my understanding (I don’t work directly with anchoring and mooring gear) is that the already enormous brakes are actually pretty marginal at slowing/stopping the chain. Basically there’s a terminal anchor velocity that, if exceeded, you won’t be able to slow/stop it.
