Definition

Noun

  • The section from amidships to the stern of a vessel on either side (i.e. port/starboard quarter).
  • Referring to a bearing of 45 degrees on either side from dead astern.

Origin

16th century. Apparently in reference to the quarterdeck.

Comments

Essentially, the opposite of the direction of the port/starboard bow. Hence, if a vessel is divided up into fourths, the quarters would be the two adjacent corners opposite the bow. It can also refer to the direction that the wind is striking the vessel, such “on the port/starboard quarter,” meaning that the wind is coming from astern on some bearing.
