Load line mark and additional load lines on the hull of a ship. Load lines are indicated by special markings on the hull. The marking for the main load line, the summer load line, is called load line mark or Plimsoll mark (positioned amidships), the marks for other conditions are named after the condition suffixed with "load line" (e.g. winter ...
Hence, waterlines are a class of "ships lines" used to denote the shape of a hull in naval architecture lines plans. [1] The load line (also known as Plimsoll line) is the waterline which indicates the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy. [2]
The convention pertains specifically to a ship's load line, a marking of the highest points on a ship's hull that can safely meet the surface of the water; a ship that is loaded to the point where its load line is underwater and no longer visible has exceeded its draft and is in danger because its capacity has been exceeded.

Graphical representation of the dimensions used to describe a ship. Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member.
Load line may refer to: Load line (watercraft), related to ship construction; Load line (electronics), a method of determining operating points in circuits with non ...
The Load Line Conference of 1966 imposed a requirement that hatch covers be able to withstand load of 1.74 tons/m 2 due to sea water, and a minimum scantling of 6 mm for the tops of the hatch covers. The International Association of Classification Societies then increased this strength standard by creating its Unified Requirement S21 [ 71 ] in ...
In this approach, the lighters were individually lifted onto the carrier ship by a large gantry crane located at the stern of the ship. The crane could move the entire length of the ship and stack the lighters atop each other in the ship's body and on the deck. The cranes had a load-carrying capacity of more than 500 Mp.
On container ships the position of containers are identified by a bay-row-tier coordinate system. The bays illustrate the cross sections of the ship and are numbered from bow to stern. The rows run the length of the ship and are numbered from the middle of the ship outwards, even numbers on the port side and odd numbers on the starboard side ...
