Port: the left side of the ship, when facing forward (opposite of "starboard"). [1] Starboard: the right side of the ship, when facing forward (opposite of "port"). [1] Stern: the rear of a ship (opposite of "bow"). [1] Topside: the top portion of the outer surface of a ship on each side above the waterline. [1] Underdeck: a lower deck of a ...
For the most part, cruise ships, whether ocean or river, are divided into three sections: forward, or the front of the ship; midship, in the middle of the ship; and aft, or the back of the ship ...
Farther aft than the beam; a relative bearing of greater than 90 degrees from the bow; e.g. "two points abaft the beam, starboard side" would describe "an object lying 22.5 degrees toward the rear of the ship, as measured clockwise from a perpendicular line from the right side, center, of the ship, toward the horizon".

The sheer forward is usually twice that aft. Increases in the rise of the sheer forward and aft build volume into the hull, and in turn increase its buoyancy forward and aft, thereby keeping the ends from diving into an oncoming wave and slowing the ship. In the early days of sail, one discussed a hull's sheer in terms of how much "hang" it had.
Weather helm is the result of a leeward and aft shift of a vessel's vector center of effort (the direction to which the force generated by the sails is pushing). This shift is caused by excess pressure on the mainsail , which overpowers the windward lateral resistance generated by the jib (or other head sail) and keel or centerboard.
Midship coefficient (C m or C x) is the cross-sectional area (A x) of the slice at midships (or at the largest section for C x) divided by beam x draft. It displays the ratio of the largest underwater section of the hull to a rectangle of the same overall width and depth as the underwater section of the hull.
Graphical representation of the dimensions used to describe a ship. Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member.
4. : The left side of a ship or vessel when facing forward (formerly larboard). Denoted with a red light at night. [2] 5. Toward the left-hand side of the ship when facing forward (formerly "to larboard "). 6. : A sweep rower who rows with one oar on one side of a boat and primarily on the port (left) side of the boat.
