In naval architecture an afterdeck or after deck or sometimes the aftdeck aft deck or a-deck is the open deck area toward the stern or aft back part of a ship or boat. The afterdeck can be used for a number of different purposes. Not all ships have an afterdeck. In place of the afterdeck a ship may be built with a poop deck, that is a deck that forms the roof of a cabin built in the rear, or "aft", part of the superstructure of a ship. A poop deck usually is higher up than an afterdeck. A ship may have its superstructure or aftercastle located in the stern and thus not have an afterdeck. The stern and afterdeck of a ship are usually more smooth and stable than the bow (front) of the ship in motion.

A taffrail is the handrail around the open afterdeck or poop deck. On wooden sailing ships like man-of-war or East Indiaman the taffrail is usually a hand carved wood rail and often highly decorated.[1]
