Morphology

boattail = boat + tail (transparent) = boat + tail

The meaning is directly derived from 'boat' + 'tail' describing a rear part shaped like a boat's stern, which is readily inferable by learners.

Etymology

Boattail is formed from boat + tail, where 'tail' means the back and a boat's rear narrows to move smoothly through water. So a boattail car or trailer has a rear that narrows like a boat to cut through the air and reduce resistance.
