Difference between Abaft, Aft and Astern

Abaft, aft and astern all are nautical terms meaning behind or to or at the rear (of).

Abaft (opposed to afore) commonly suggests position relatively nearer the stern or rear part of the ship.

Astern (opposed to ahead) chiefly implies position outside and to the rear of a ship.
