Waterline of a ship. The mark above the waterline indicates the Plimsoll line. The waterline is the line where the hull of a ship meets the surface of the water.. 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.
A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline.
Lines plan for the hull of a basic cargo ship MS Freedom of the Seas under construction in a shipyard in Turku. A ship will pass through several stages during its career. The first is usually an initial contract to build the ship, the details of which can vary widely based on relationships between the shipowners, operators, designers and the ...
The ship lies broadside to the current, with the main topsail backed and the fore and mizzen topsail full: essentially a hove-to position. Selective backing and filling of these sails moves the ship ahead or astern, so allowing it to be kept in the best part of the channel. A jib and the spanker are used to help balance the sail plan. This ...

Lofting is the transfer of a Lines Plan to a Full-Sized Plan. This helps to assure that the boat will be accurate in its layout and pleasing in appearance. There are many methods to loft a set of plans. Generally, boat building books have a detailed description of the lofting process, beyond the scope of this article.
For ships and aircraft, routes are typically straight-line segments between waypoints. A navigator determines the bearing (the compass direction from the craft's current position) of the next waypoint. Because water currents or wind can cause a craft to drift off course, a navigator sets a course to steer that compensates for drift.
A full-rigged ship or fully rigged ship is a sailing vessel with a sail plan of three or more masts, all of them square-rigged. [1] Such a vessel is said to have a ship rig or be ship-rigged, with each mast stepped in three segments: lower, top, and topgallant. [2] [3] [4]
