Capsizing is a phenomenon that occurs when a boat or ship is overturned in the water due to strong winds, waves, or other external forces. The term 'keels' refers to the bottom of the boat or ship, which is usually made of metal and is designed to provide stability and balance. When a boat or ship capsizes, the keels are often the first part to be affected. The term 'tips' refers to the top of the boat or ship, which is usually made of wood or fiberglass and is designed to provide protection from the elements. When a boat or ship capsizes, the tips are often the last part to be affected. When a boat or ship capsizes, it is said to have 'OVER' capsized.
