In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. [1] In commercial vessels, the latter criterion measured relative to the ship's load line , regardless of deck arrangements, is the mandated and regulated meaning.
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 ...
Comparison of 1 square yard with some Imperial and metric units of area. The square yard (Northern India: gaj, Pakistan: gaz) is an imperial unit and U.S. customary unit of area. It is in widespread use in most of the English-speaking world, particularly the United States, United Kingdom, Canada, Pakistan and India.
When a ship heels (rolls sideways), the centre of buoyancy of the ship moves laterally. It might also move up or down with respect to the water line. The point at which a vertical line through the heeled centre of buoyancy crosses the line through the original, vertical centre of buoyancy is the metacentre.
Either of the braces attached to the yard of the mainsail (the largest and lowest sail on the mainmast) on a square-rigged vessel. mainmast. Also simply main. 1. The tallest mast on a ship [1] with more than one mast, especially the tallest mast on a full-rigged ship. 2. On a ship with more than one mast, the second mast from the bow. mainmast head
The refrigerator is on sale for $1,200 and her sales tax rate is 6%. 1,200 multiplied by 0.06 is 72, so Sarah would pay $72 in sales tax. This would bring her total bill to $1,272.
Thus, when the yards hang at right angles with the mast they are said to be 'square by the lifts;' when perpendicular to the ship's length, they are 'square by the braces;' but when they lie in a direction perpendicular to the plane of the keel, they are 'square by the lifts and braces.' The yards are said to be very square when they are of ...
