What does knockdown mean Sailing?

In sailing, "knockdown" refers to a situation where a strong gust of wind causes a sailboat to heel excessively, often to the point where water begins to enter the cockpit or even the cabin. This can occur when the sails are overpowered, leading to a loss of control. A knockdown can be dangerous, as it may result in capsizing if not managed properly. Sailors often take precautions to prevent knockdowns by adjusting sail trim and reducing sail area in strong winds.
