Which factor does NOT affect the required freeboard of a cargo vessel? A vessel has a maximum allowable draft of 28 feet in salt water and a fresh water allowance of 8 inches. At the loading berth the water density is 1.011. To what draft can she load in order to be at her mark when she reaches the sea? (the salt water density is 1.025) You must shift a weight from the upper tween deck to the lower hold. This shift will ______ For a vessel inclined by the wind, multiplying the buoyant force by the horizontal distance between the lines of action of he buoyant and gravity forces give the . ______ A vessel with a large GM will A vessel continually list to one side and has a normal rolling period. Which statement is TRUE? Reference to freeboard categories, type A vessels are those designed specifically for the carriage of _____? The term deadweight refers to the cargo carrying capacity including fuel,water and stores measured; Vessel has a fresh allowance of 175 mm. By how much will she charge Her draft if she passes from water of density 1,004 to water of density 1.021 kgg/m3 Will the internal and external forces acting on a bulk carrier cross section change during loading operation? The strictest load line regulations apply to The correction to KG for longitudinal free surface effects for a vessel can be found by dividing the vessel’s displacement with the; What will happen to the center of gravity of a vessel when weight is added on a vessel? Signs of racking stresses generally appear at the A term “ scantling “ refers to the A cargo plan would NOT include Personal in charge of cargo stowage and security cargo should have: I.Proper qualification and experience II. A sound practical knowledge of the application and content of Cargo Security Manual Your ship 12,000 tons displacement has a center of gravity 21.5 ft above the keel. You run aground and estimate the weight aground is 2,500 tons. The virtual rise in the center of gravity is ___ Cargo transport units, including freight containers shall be loaded , stowed and secured throughout the voyage in accordance with the cargo securing manual approved by the _ On a cargo crane, the boom indicator tells the operator what angle the boom angle is compared to the _____ On a yard-and-stay rig, the boom spotted directly over the hatch is called A “ bullrope “ is used for All lashings and components used for securing should possess breaking strength of not less than ____ Binder chains used to lash down deck cargoes may be shortened by “ TOM “ is a timber used to secure cargo by running from ___ I. An upper support down in the cargo II. A lower support unto the cargo When stowing bagged cargo, you wish to maintain a vertical wall or bulkhead as the stowage progresses. The bulkhead extends from one side of the vessel to the other and exceed one section foreward of the square, from the lower hold up to the tween decks. The stability of
