2. Hull (watercraft) - Wikipedia

   en.wikipedia.org/wiki/Hull_(watercraft)

   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 ...

3. Ship resistance and propulsion - Wikipedia

   en.wikipedia.org/wiki/Ship_resistance_and_propulsion

   Sketch by Tudor shipwright Mathew Baker. A ship must be designed to move efficiently through the water with a minimum of external force. For thousands of years ship designers and builders of sailing vessels used rules of thumb based on the midship-section area to size the sails for a given vessel.

4. Wave-making resistance - Wikipedia

   en.wikipedia.org/wiki/Wave-making_resistance

   For example, if the ship takes three seconds to travel its own length, then at some point the ship passes, a stern wave is initiated three seconds after a bow wave, which implies a specific phase difference between those two waves. Thus, the waterline length of the ship directly affects the magnitude of the wave-making resistance.

5. Lake freighter - Wikipedia

   en.wikipedia.org/wiki/Lake_freighter

   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 ...

6. Draft (hull) - Wikipedia

   en.wikipedia.org/wiki/Draft_(hull)

   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.

7. Hull speed - Wikipedia

   en.wikipedia.org/wiki/Hull_speed

   Hull speed can be calculated by the following formula: where is the length of the waterline in feet, and is the hull speed of the vessel in knots. If the length of waterline is given in metres and desired hull speed in knots, the coefficient is 2.43 kn·m −½.
