In shipbuilding, the outer planking or structural ridge on the rear or after-section of a vessel's hull.
Nautical compound of 'after' (rear) and 'wale' (from Old English 'walu,' meaning ridge or plank). Specialized shipbuilding terminology that dates to medieval maritime construction.
Every part of a wooden ship had a specific name because sailors and builders needed exact communication—the afterwale reinforced the rear section and helped the ship withstand the stresses of waves and wind!
