can anyone identify this object?

[Jetfish]

Anyone have any thoughts on this object? Looks like part of an anchor, but hard to be sure. If thats what it is, trying to identify exactly what type, from what time period etc. has been unsuccessful thus far. Just wondered if anyone out there has any ideas? The object is located on the lower east coast of Florida.

Thanks!

Looks like a piece of modern machinery but I'm no expert.

Doesn't look like any anchor I've ever seen.
