1. Centreboard

   A centreboard or centerboard (US) is a retractable hull appendage which pivots out of a slot in the hull of a sailboat, known as a centreboard trunk (UK) or centerboard case (US). The retractability allows the centreboard to be raised to operate in shallow waters, to move the centre of lateral resistance (offsetting changes to the sailplan that move the centre of effort aft), to reduce drag when the full area of the centreboard is not needed, or when removing the boat from the water, as when trailering. A centreboard which consists of solely a pivoting metal plate is called a centerplate. A daggerboard is similar but slides vertically rather than pivoting. The analog in a scow is a bilgeboard: these are fitted in pairs and used one at a time.

1. centreboard

   A centreboard is a retractable keel or blade that extends from the bottom of a sailboat or other type of vessel. It is designed to provide stability and improved handling when sailing, counteracting the lateral force of the wind and preventing the boat from getting pushed off course. The centreboard can be raised or lowered depending on the depth of the water and the sailing conditions.
