Bias Stability - The maximum expected drift in a sensor’s output. This can be measured as a function of time or as a function of temperature.
stability
Technically, a boat's tendency to return to her normal position, but usually refers to her resistance to heeling, capsize, rolling, and yawing.
Stability curves are obtained on the assumptions I. That all openings in the upper deck, forecastle and poop (if any) are covered in and made watertight; and the buoyancy of any erections above there decks is generally neglected.

She was to be decked, a trunk cabin fitted up, and a false keel added to give her stability and enable her to go to windward. For general handiness, I decided to rig her as a ketch.

BALLAST - Heavy substances loaded by a vessel to improve stability, trimming, sea-keeping and to increase the immersion at the propeller.
The most significant stability criterion - capsize. Caused by waves, wind and can be induced by yaw.
Pitch (Around y). A rocking motion between bow and stern. Mostly wave induced.
Yaw (Around z). This is what the rudder is supposed to do.
The keel surface on the bottom of the hull gives the ship greater directional control and stability. In non sailing hulls, the keel helps the hull to move forward, rather than slipping to the side.
These versatile kayaks offer good stability and improved tracking and efficiency. Large open cockpits permit easy entry and exit, and allow you to stretch your legs as well as stow your gear.
Beam or frame that holds the slings vertical when hoisting a load, to prevent damage to cargo. Stability
The capacity of a vessel to return to its original position after having been displaced by external forces.
ballast - An additional weight placed low in the hull (usually for stability); ballast may be external or internal. A ship is said to be in ballast when she has no merchandise on board, but only sand, gravel, mud, or rubbish as ballast.

It also increases the boat's stability and aids in steering it.
Knot

Bar: A sand, mud or debris shoal, as across the mouth of a river or harbor.
Load displacement and water movement in the hold are two factors that affect the boat's stability. Therefore, the load must be secured (tied down) near the hold with ropes, and the hold kept dry.
