PLANS OF WOODEN VESSELS, selected as types from one hundred and fifty of various kinds and descriptions, from a fishing smack to the largest clipper ships and vessels of war, both sail and steam, built by Wm. H. Webb, in the city of New York, from the year 1840 to 1869
Scale: 1:48 Plan, showing the body plan, sheer lines with inboard details, and longitudinal half-breadth for Crache Feu, by Edward Tippet [Master Shipwright, Portsmouth Dockyard, 1793-1799], National Maritime Museum, Greenwich. Crachefeu was a French Navy gun brig launched in 1793.
For small angles, M can also be considered to be fixed, while B moves as the ship heels. The metacentric height (GM) is a measurement of the initial static stability of a floating body. [1] It is calculated as the distance between the centre of gravity of a ship and its metacentre. A larger metacentric height implies greater initial stability ...
Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged. Stability calculations focus on centers of gravity , centers of buoyancy , the metacenters of vessels, and on how these interact.
A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". [1] That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed.
Graphical representation of the dimensions used to describe a ship. Dimension "b" is the beam at waterline.. The beam of a ship is its width at its widest point. The maximum beam (B MAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H) only includes permanently fixed parts of the hull, and beam at waterline (B WL) is the maximum width where the ...
Definitions. Beam – A measure of the width of the ship. There are two types: Beam, Overall (BOA), commonly referred to simply as Beam – The overall width of the ship measured at the widest point of the nominal waterline. Beam on Centerline (BOC) – Used for multihull vessels. The BOC for vessels is measured as follows: For a catamaran: the ...
Simpson's rules are a set of rules used in ship stability and naval architecture, to calculate the areas and volumes of irregular figures. [1] This is an application of Simpson's rule for finding the values of an integral, here interpreted as the area under a curve. Simpson's First Rule.
