A fishing line carrier device for use in downrigger fishing. The device includes a main body portion. A bow extends from the front of the main body portion. A tail extends from the rear of the main body portion and includes a vertical stabilizer and a horizontal stabilizer. The horizontal stabilizer has a flap extending downwardly from its trailing edge. A vertically disposed central plane extends from the bow to the tail. A bore extends vertically through the main body portion along the central plane. A diagonally extending access slot extends from the outer surface of the body to the central plane. Upper and lower access slots communicate the diagonally extending access slot with the bore. A locking pin receiving tunnel extends along the diagonally extending access slot and is adapted to receive a locking pin after the carrier device is positioned onto a downrigger line.
