    Lloyd’s Register (“LR”) load line mark and lines and timber load line mark and lines for power-driven merchant vessels Lloyd’s Register (“LR”) load line mark and lines for commercial sailing vessels. The original "Plimsoll mark" was a circle with a horizontal line through it to show the maximum draft of a ship.

    en.wikipedia.org/wiki/Stowage_plan_for_container...

    40 feet container size is: 40 ft (12 m) length by 8 ft (2.4 m) width by 8.6 ft (2.6 m) height. Container vessels are built to contain as many containers as possible, accordingly the vessels are divided into sections: Accommodation, the space which contains all crew cabins; Bridge, the command center of the ship, the space which contains ...

    en.wikipedia.org/wiki/Field_capacity

    Field capacity is the amount of soil moisture or water content held in the soil after excess water has drained away and the rate of downward movement has decreased. This usually occurs two to three days after rain or irrigation in pervious soils of uniform structure and texture.

    en.wikipedia.org/wiki/Unified_Soil...

    The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt):

  6. Draft (hull) - Wikipedia

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

[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.

A waterline can also refer to any line on a ship's hull that is parallel to the water's surface when the ship is afloat in a level trimmed position.

  8. Ship measurements - Wikipedia

    en.wikipedia.org/wiki/Ship_measurements

    Used mainly to determine the minimum water depth for safe passage of a vessel and to calculate the vessel's displacement (obtained from ship's stability tables) so as to determine the mass of cargo on board. Draft, Air – Air Draft/Draught is the distance from the water line to the highest point on a ship (including antennas) while it is ...

  9. Hopper barge - Wikipedia

    en.wikipedia.org/wiki/Hopper_barge

    The vessel consists of two major moving parts (port and starboard halves), both are mostly symmetrical in design. Both parts of the vessel are hinged at the deck and operated by hydraulic cylinders. When the vessel splits the load is dumped rapidly, which means the barge has to be very stable in order not to capsize or otherwise get damaged.
