Where does the term “Pink Stern” come from and What does Pink Stern mean?

Pinkeye designates an inflamed eye, but pink-stern has nothing to do with color.

It names a type of small boat, one with its stern shaped like that of a sailing vessel known as a pink or pinky.

Both names are corrupted from the Middle Dutch pincke, first applied to a flat-bottom sailing vessel which was subsequently built with a narrow stern, the so-called pink-stern.
