Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged. Stability calculations focus on the center of gravity, center of buoyancy, and metacenter of vessels and on how these interact.
Ship stability, as it pertains to naval architecture, has been taken into account for hundreds of years. Historically, ship stability calculations for ships relied on rule of thumb calculations, often tied to a specific system of measurement. Some of these very old equations continue to be used in naval architecture books today. However, the advent of calculus-based methods of determining stability, particularly Pierre Bouguer's introduction of the concept of the metacenter in the 1740'S ship model basin allows much more complex analysis.
Master shipbuilders of the past used a system of adaptive and variant design. Ships were often copied from one generation to the next with only minor changes being made; by replicating a stable design serious problems were not often encountered. Ships today still use the process of adaptation and variation that has been used for hundreds of years; however computational fluid dynamics, ship model testing and a better overall understanding of fluid and ship motions has allowed much more analytical design.
Some amount of stability is indeed returning to the economy, no doubt ... More specifically, it was the Stand-by Arrangement (SBA) announced by the IMF in the closing weeks of the previous government that began to steady the ship. Steadfast implementation of the programme since then, and adherence to its targets, has helped bring about this stability.
Norway's Accident Investigation Board has completed a review of the fatal accident aboard the expedition cruise ship VikingPolaris last November, when a high wave struck the side of the ship and broke multiple windows ...Passengers aboard the ship described the experience of the wave's impact as feeling like the vessel had hit an iceberg.

In the summer of 1976, three 400-foot piers were completed on the north side of the Port and the USS Vangaurd, a NASA-sponsored tracking ship, docked for one year at the north-south pier while the scrapyard was stabilized on the north side ... yard was stabilized on the north side.

“Supposedly, those ships are there as part of a counter-piracy mission,” he said ... The USS Mason, a guided-missile destroyer, and allied ships from a counter-piracy task force that operates in the Gulf of Aden and off the coast of Somalia responded to the call for help and “demanded release of the vessel” upon arrival, Central Command said.
Erik Kurilla, commander of US Central Command, said in the statement on Sunday that maritime domain security ‘is essential to regional stability.” “We will continue to work with allies and partners to ensure the safety and security of international shipping lanes,” Kurilla said.
Porter had been relegated to shore duty ever since his first ship, the USS Boxer, had been wrecked in an accident near the mouth of the Mississippi River in 1817. In early 1823, Porter was assigned command of a second ship, the USS Greyhound... His role aboard ship would be to function as a lieutenant in assisting Porter.
