What is this fitting?

It is part of an anchor chock to keep a Danforth on deck.

Thanks!
apparently the rest is missing?

[mitiempo]

Looks like whoever installed it used it as a cleat for the anchor or dockline maybe?

It's a chain cleat.

My uncle has a couple on his Figaro Six

I vote for the 'chain cleat' purpose given the way it's installed... but it sure looks like part of the Danforth Storage setup Brian found.

Looks like you need some of that Spotless Stainless on your pushpit fitting and your snap shackle. Just sayin'.

Regards,

Looks like a "toe stubber" to me, useful for nothing but. It's not robust enough to use as a cleat for anything but light stuff.
Take it out, seal it up and reduce do your part to reduce toe injuries.

Carrying handle?

That must be it, I'll look for one like it on the the other end.
