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 centers of gravity , centers of buoyancy , the metacenters of vessels, and on how these interact.
In a boat, the equivalent of the spring stiffness is the distance called "GM" or "metacentric height", being the distance between two points: "G" the centre of gravity of the boat and "M", which is a point called the metacentre. Metacentre is determined by the ratio between the inertia resistance of the boat and the volume of the boat. (The ...
Before "yawl" became the name of a rig, it was a hull type. Generally, a yawl is a double-ended, clinker built open boat, which can be worked under sail or oar. They are considered to have Viking or Norse influence in their design. Most were operated from a beach or a small harbour, with the boat being hauled out of the water when not in use. [10]
Generally, a rudder is "part of the steering apparatus of a boat or ship that is fastened outside the hull, " denoting all types of oars, paddles, and rudders. [1] More specifically, the steering gear of ancient vessels can be classified into side-rudders and stern-mounted rudders, depending on their location on the ship.
The aft part of the vessel is supported in the water by the lower half of the propeller, which is designed to operate semi-submerged at all times. The goal is to keep as little of the boat in contact with the water as possible, as water is much denser than air, exerting more drag on the vehicle. Essentially the boat 'flies' over the surface of ...
Cross section of a vessel with a single ballast tank at the bottom. A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural ...
Diagram of the steering gear of an 18th- to 19th-century sailing ship [3]: 151 Helm of TS Golden Bear. A ship's wheel is composed of eight cylindrical wooden spokes (though sometimes as few as six or as many as ten or twelve depending on the wheel's size and how much force is needed to turn it.) shaped like balusters and all joined at a central wooden hub or nave (sometimes covered with a ...
The advantage of water ballast is that the tanks can be emptied, reducing draft or the weight of the boat (e.g. for transport on ground) and water added back in (in small boats, simply by opening up the valves and letting the water flow in) after the boat is launched or cargo unloaded.
