Abstract

A centreboard unit for a sail boat includes a centreboard (16) articulated with respect to the hull (10) of the boat about an axis (A; B) which lies in a longitudinal midplane of the boat, a ballast (18) associated with the centreboard (16), and control means (24, 26) for controlling the rotation of the centreboard (16) about such an axis (A; B) in order to cause a lateral movement of the ballast (18) with respect to said longitudinal plane. Additional means (20, 22, 24, 26; 20, 22, 42; 21) are provided, which are adapted to be operated also during navigation for changing the position of the centreboard (16) with respect to the hull (10), with the aim of affecting the operational attitude of the centreboard.
