The squat effect is the hydrodynamic phenomenon by which a vessel moving through shallow water creates an area of reduced pressure that causes the ship to increase its draft (alternatively decrease the underkeel clearance of the vessel in marine terms) and thereby be closer to the seabed than would otherwise be expected.
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 ...
Lake vessels are designed with the greatest block coefficient to maximize the vessel's size in the locks within the Great Lakes/St Lawrence Seaway system. Therefore, ship designers have favored bluff bows over streamlined bows. [citation needed] Another distinguishing feature of lake vessels versus ocean vessels is the cargo hatch configuration ...

A ship is a large vessel that travels the world's oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats , based on size, shape, load capacity and purpose.
The fishermen held aloft red flares as they circled their boats outside Saint-Malo to block the Normandy Trader's path - a prelude to a planned blockade later on Friday of Calais and the Channel ...
Greenpeace has placed a number of boulders on an area of seabed off the coast of Cornwall in an attempt to block what it describes as “destructive industrial fishing”. ... ship Arctic Sunrise ...
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.
