__________________is affected by movement of the center of gravity or center of buoyancy or by some outside forces, such as wind and waves. ---------CORRECT ANSWER-----------------Equilibrium _____________________ stability tends to keep the vessel from rolling over (capsizing). Additional weight above the center of gravity increases the distance from the center of gravity up to the center of buoyancy. As a result, stability is also decreased. Removal of weight from below the center of gravity also decreases stability. If the center of gravity is raised enough, the vessel will become unstable. ---------CORRECT ANSWER-----------------Transverse (athwart ships) _____________________forces are caused by actions outside the hull such as wind and waves. ---------CORRECT ANSWER-----------------DYNAMIC ________________forces are caused by placement of weight within the hull. Adding weight on one side of a vessel's centerline or above its center of gravity usually reduces stability. Flooding or grounding a vessel makes it susceptible to static forces which may adversely affect stability. ---------CORRECT ANSWER--------- --------STATIC Damage to the hull of a vessel can create ____________________________ with the sea, permitting the movement of sea water into and out of the vessel.
