thumb|Shipboard bitts thumb|Shoreside bitts Bitts are paired vertical wooden or metal posts mounted either aboard a ship or on a wharf, pier, or quay. The posts are used to secure mooring lines, ropes, hawsers, or cables. Bitts aboard wooden sailing ships (sometime called cable-bitts) were large vertical timbers mortised into the keel and used as the anchor cable attachment point. Bitts are carefully manufactured and maintained to avoid any sharp edges that might chafe and weaken the mooring lines.

thumb|right|Two scuppers cut into either side of this outdoor stairwell prevent water from building up and making the stairs slippery. A scupper is an opening in the side walls of a vessel or an open-air structure, which allows water to drain instead of pooling within the bulwark or gunwales of a vessel, or within the curbing or walls of a building. thumb|upright|Ship's bulwark. 1.

Outriggers may also refer to legs on a wheeled vehicle that are folded out when it needs stabilization, for example on a crane that lifts heavy loads. ==Powered vessels and sailboats==

thumb|right|A traditional ship's mast, consisting of "lower" (i.e. Main-, Fore- or Mizzen-) mast, topmast and topgallant/royal mast. The topmast is highlighted in red. The masts of traditional sailing ships were not single spars, but were constructed of separate sections or masts, each with its own rigging. The topmast is one of these.

The U-shaped arrangement of seats at the stern of the boat are the Glossary of nautical terms (M-Z)#sternsheets|sternsheets A thwart is a part of an undecked boat that provides seats for the crew and structural rigidity for the hull. A thwart goes from one side of the hull to the other. There may be just one thwart in a small boat, or many in a larger boat, especially if several oarsmen need to be accommodated.

thumb|Hatch coaming (bottom right) on a bugeye Coaming is any vertical surface on a ship designed to deflect or prevent entry of water. It usually consists of a raised section of deck plating around an opening, such as a cargo hatch. Coamings also provide a frame onto which to fit a hatch cover.

A skeg (or skegg or skag) is a sternward extension of the keel of boats and ships which have a rudder mounted on the centre line. The term also applies to the lowest point on an outboard motor or the outdrive of an inboard/outboard. In more recent years, the name has been used for a fin on a surfboard which improves directional stability and to a movable fin on a kayak which adjusts the boat's centre of lateral resistance (it moves the center of resistance relative to the center of effort). The term is also often used for the fin on water skis in the U.S. It has been used for the vertical fin
