Starboard Quarter
The after part of a vessel’s starboard side, or the relative direction abaft the starboard beam.
As a structural location it lies towards the stern on the right when facing forward. As a lookout report, an object on the starboard quarter lies in the sector between approximately abeam and astern to starboard.
The directional reference moves with the vessel. Superstructure or sails can create blind sectors, so reports should include bearing, range and movement when needed for navigation or collision assessment.
