The volume of a ship's hull below the waterline (solid), divided by the volume of a rectangular solid (lines) of the same length, height and width, determine a ship's block coefficient. Coefficients [5] help compare hull forms as well: Block coefficient (C b) is the volume (V) divided by the L WL × B WL × T WL. If you draw a box around the ...

The total amount of water to be displaced by a moving hull, and thus causing wave making drag, is the cross sectional area of the hull times distance the hull travels, and will not remain the same when prismatic coefficient is increased for the same lwl and same displacement and same speed.
This is understood to be a function of the Block coefficient of the vessel concerned, finer lined vessels Cb <0.7 squatting by the stern and vessels with a Cb >0.7 squatting by the head or bow. [1] Squat effect is approximately proportional to the square of the speed of the ship.
Full hulls, with large block coefficients, are almost universal, and as a result, bulk carriers are inherently slow. [4] This is offset by their efficiency. Comparing a ship's carrying capacity in terms of deadweight tonnage to its weight when empty is one way to measure its efficiency. [4] A small Handymax ship can carry five times its weight. [4]
In total, 300,000 pieces of steel were assembled into 94 "blocks" off the dry dock, which were then positioned and welded together to complete the hull and superstructure. [18] After floating out on 21 March 2003, the Queen Mary 2 was fitted out in the large fitting out basin ("Bassin C"), the first ship to use this huge dry dock since the ...

Builder's Old Measurement (BOM, bm, OM, and o.m.) is the method used in England from approximately 1650 to 1849 for calculating the cargo capacity of a ship.It is a volumetric measurement of cubic capacity.
