Details and Deadeyes

One of the many details in the rigging of a vessel, especially a sailing vessel, is a round wooden disc with holes in it called a deadeye, as seen here aboard the schooner Merrie Ellen.

A concise explanation of how it is used is given here by Wikipedia.
A deadeye is an item used in the standing and running rigging of traditional sailing ships. It is a smallish round thick wooden disc with one or more holes through it, perpendicular to the plane of the disc. Single and triple-hole deadeyes are most commonly seen.
Triple deadeyes are used in pairs; a line called a lanyard is run back and forth between them, through the holes, so that they function again much as a block and tackle would. This provides a mechanical advantage, pulling harder on whatever the deadeyes are attached to. Pairs of deadeyes are placed in the shrouds (the lines that hold up the mast), where they are used to create greater tension in the shrouds.
In recent decades, as steel wire became the prevalent material for sailboat rigging, deadeyes and lanyards gave way to metal turnbuckles for tensioning the wires. More recently, however, with the advent of high-strength and low-stretch synthetic fibres, some sailboats are using synthetic rope for standing rigging, and deadeyes and lanyards are coming back into use as tensioning devices.

I learned something new from your post, I didn't know that term. It's called a Jungfer, a virgin, in German (I had to look that up, too).
The photo is just gorgeous.

I love the rich color in the shot, coupled with the soft drifting cloud in the back.
