People who work in shipbucket scale, often get a lot of comments containing words not commonly found in the english language or even words meaning different things when applied to ships and ship design. This page is created by Acelanceloet to provide a reference for such words. This article will provide an explanation of words describing ships dimensions (both real and relative), ship shapes, ship stability etc. It is allowed and even encouraged to improve, add to and expand these explanations. Definitions too complicated to fit in a few sentences deserve their own articles in the future, which will be linked from this page.
Dimensions
- Length over all
- Abbreviated as LOA
- The length from extreme bow to extreme stern of the hull of a ship.
- Length on Waterline
- Abbreviated as LWL
- The length of a ship on the design waterline.
- Length between perpendiculars
- Abbreviated as LPP
- The point where the bow of a ship enters the water when at design draft, fore end of the design waterline
- Aft Perpendicular
- Abbreviated as A.P.
- Depending on the ships design, either
- The aftmost side of the rudder post
- The centerline of the rudder stock if there is no rudder post
- ships with unusual stern shapes normally don't use the "perpendicular" description. If they do though, it either follows a 'rule length' or is the aft end of the design waterline.
- Fore Perpendicular
- Abbreviated as F.P.
- The length of a ship between fore perpendicular and aft perpendicular
- Beam
- Abbreviated as B
- The greatest width of a ship, measured in the inner shell.
- Largest Beam
- Abbreviated as BMAX
- The greatest width of a ship, including shell thickness.
- Depth
- Abbreviated as D
- The distance between the top of the keel to the top of the deck beam at side of the uppermost continuous deck, measured amidships. (= 0,5*LWL)
- Draft
- Abbreviated as T
- The greatest distance between keel and waterline at a load condition. If just the draft is given, this is design draft.
- Draft over all
- Abbreviated as TOA
- The distance between the waterline and the lowest point of the ship.
- Displacement
- Abbreviated as Δ
- The volume of water a ship "displaces" when it's total weight is in the water. Equal to Volume * density of the water. Displacement in meters is equal to the ships weight in metric tons.
- Equal to Volume when the ship is in fresh water (density = 1t/m3)
- Volume
- Abbreviated as ∇
- The volume of a ship below the design waterline.
