Draft markings on the stern of the Cutty Sark, an example of the Imperial system of such markings. The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. [1] Draft varies according to the loaded condition of the ship.
Air draft is the minimum height a ship needs to pass under, while standard draft is the minimum depth a ship needs to float over. Length between perpendiculars – The distance between where the forward part cuts the waterline and the rudder post of the ship.
A cylinder with longitudinal draft Profile view of a drafted cylinder with the draft dimension. In engineering, draft is the amount of taper for molded or cast parts perpendicular to the parting line. It can be measured in degrees or mm/mm (in/in). Consider the fabrication of a hollow plastic box, without lid.
Influence of mainsail draft position on forward and side force. In nautical parlance, the draft or draught of a sail refers to the amount and shape of curvature in a horizontal cross-section. [1] Any sail experiences a force from the prevailing wind just because it impedes the air's passage.
Draft marks, by showing how low a ship is sitting in the water, make it possible to determine displacement. The displacement or displacement tonnage of a ship is its weight . As the term indicates, it is measured indirectly, using Archimedes' principle , by first calculating the volume of water displaced by the ship, then converting that value ...
A bill of exchange or "draft" is a written order by the drawer to the drawee to pay money to the payee. A common type of bill of exchange is the cheque (check in American English), defined as a bill of exchange drawn on a banker and payable on demand. Bills of exchange are used primarily in international trade, and are written orders by one ...
Draft (engineering), the angle added to features perpendicular to the parting line of a casting or molding; Draft (aerodynamics), two objects in close proximity reducing overall drag; Draft document, a version of an unfinished document or other written work; Draft animal, an animal used to perform tasks
The vessel's clearance is the distance in excess of the air draft which allows a vessel to pass safely under a bridge or obstacle such as power lines, etc.A bridge's "clearance below" is most often noted on charts as measured from the surface of the water to the underside of the bridge at the chart datum Mean High Water (MHW), [3] [4] a less restrictive clearance than Mean Higher High Water ...
