what is the stern and bow of a boat
Bow (ship) The bow /ˈbaʊ/ is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. Both of the adjectives fore and forward mean towards the bow. The other end of the boat is the stern.
Hull (watercraft) The hull is the watertight body of a ship or boat. Above the hull is the superstructure and/or deckhouse, where present. The line where the hull meets the water surface is called the waterline.
Port and starboard To understand which is which, when a person is facing the bow on a vessel or aircraft, that is, forward towards the direction the vehicle is heading when underway, the port side is the left-hand side and the starboard side is the right-hand side. However, port and starboard never change; they are unambiguous references that are not based on the relative directions of an observer, just like the cardinal directions of east and west don't change no matter the direction a person faces.[2][3]
Boat positions In the sport of rowing, each rower is numbered by boat position in ascending order from the bow to the stern (with the exception of single sculls). The person who is seated on the first seat is always the 'bow', the closest to the stern is commonly referred to as the 'stroke'. There are some exceptions to this: Rowers in continental Europe number from stern up to bow. Certain crew members have other informal titles and roles.
