Anchors

[Sledgehammer427]

I was thinking about going into enemy ports. I read stories of some kaleuns using the anchor chains of enemy merchants to determine the tides and how they would affect the torpedo shots.

Now. I think it would be doubly cool if, lets say you were waiting outside a harbor...to watch ships come in and drop or weigh anchor as they entered or exited.

This is a pretty cut and dry case of a repel boarders scenario that warranted the use of two Kar 98's and an unloaded MP 40.

LOL!

There are so many other areas where the simulation experience can be improved, that the operation of the anchor ranks down where with the soup questions.

If the developers are at the point where they are modeling the anchor, the rest of the simulation better be frickin perfect.

Maybe use him as a decoy:

Look there Captain, a German u-boa... ah no it's just a polar bear. Relax all.

BAM

Speaking from my modern day experience we never used our anchor...for anything! We had procedures for using it, but never would have to use it. The only reason we had one was because of a Coast Guard regulation I believe. An anchor on a submarine is about as useful as a screen door on a submarine.

In the fiction book "final harbor" the author wrote that the US Sub had its anchor removed so that the chains could not shift around and make noise. The author also mentioned the possibility of the anchor coming loose during a depth charge attack.

Does that make sense or was the author BSing?

Where did you read that? Since the Germans only made one major and one minor harbor raid the entire war, that scenario seems unlikely.

Anchor chain can be pretty heavy, each link weighing in excess of 75 lbs, so I would imagine the chain locker wouldn't be affected be the violent shaking of a DC attack. A couple of links might shift towards the top, but I really can't foresee it causing any prolonged sound transient.

As for the removal of the anchor itself, it depends on what kind of boat we're talking about. A WWII fleet boat you could remove the anchor I would think and it wouldn't make a difference to the boats sound signature. Try that on a modern nuc boat and you would have a sizable hole on the exterior that could create flow noise as the water passed over the opening. The same effect you get when blowing across the top of an open bottle.

I also don't see the anchor coming loose during an attack either. When the anchor is in the stowed position the brake is set so as to prevent the weight of the anchor from pulling on the chain, and inadvertently dropping anchor. There is a "weak link" (can't remember the tech term) that attaches the anchor to the chain but even that requires quite a bit of force the break.
