Terms
- Abaft (preposition): at or toward the stern of a ship, or further back from a location, e.g. "the mizzenmast is abaft the mainmast".[1]
- Aboard: onto or within a ship, or in a group.[2]
- Above: a higher deck of the ship.[1]
- Aft (adjective): toward the stern (rear) of a ship.[1] For example, "Able Seaman Smith; lie aft!" or "What's happening aft?". Comparative is "after", e.g. "the mizzenmast is after than the mainmast".

The stern is opposite the bow, the outside (offboard) of the front of the boat. The term derives from the Old English æftan (“behind”).
