'''Capsizing''' or '''keeling over''' occurs when a [[boat]] or [[ship]] is [[rolled]] on its side or further by wave action, instability or wind force beyond the angle of positive static stability or it is [[Turtling (sailing)|upside down]] in the water. The act of recovering a vessel from a capsize is called '''righting'''. Capsize may result from [[broach (nautical)|broaching]], {{nautical term|knockdown}}, loss of stability due to cargo shifting or flooding, or in high speed boats, from turning too fast.
 
If a capsized vessel has enough flotation to prevent sinking, it may recover on its own in changing conditions or through mechanical work if it is not [[Ship stability|stable]] while inverted. Vessels of this design are called [[#Self-righting|self-righting]].
