2. Ship ballast - Wikipedia

   en.wikipedia.org/wiki/Ship_ballast

   On more advanced racing boats, a wire harness called a trapeze is used to allow the crew to hang completely over the side of the hull without falling out; this provides much larger amounts of righting moment due to the larger leverage of the crew's weight, but can be dangerous if the wind suddenly dies, as the sudden loss of heeling moment can ...

   en.wikipedia.org/wiki/Diving_weighting_system

   Clump weights for bells and stages:– A clump weight is a large ballast weight suspended from a cable which runs down from one side of the launch and recovery gantry, through a pair of sheaves on the sides of the weight, and up the other side back to the gantry, where it is fastened. The weight hangs freely between the two parts of the cable ...

   Loss of ballast weight is another cause of buoyancy gain which may not be possible to compensate by venting. [ 16 ] [ 17 ] The standard diving suit can inflate during a blowup to the extent that the diver cannot bend his arms to reach the valves, and the over-pressure can burst the suit, causing a complete loss of suit buoyancy, and the diver ...

   The ability to shed ballast weight is considered a safety feature for scuba diving. It allows the diver to achieve positive buoyancy in an emergency, but the inadvertent loss of ballast when the diver needs to control ascent rate is itself an emergency that can cause decompression illness. [70]

   Ballast Ballast is removable or permanently installed weight in an aircraft used to bring the center of gravity into the allowable range. Center-of-Gravity Limits Center of gravity (CG) limits are specified longitudinal (forward and aft) and/or lateral (left and right) limits within which the aircraft's center of gravity must be located during ...
