Heeling

A sailing vessel heels when the boat leans over to the side in reaction to wind forces on the sails.

A sailing vessel's form stability (derived from the shape of the hull and the position of the center of gravity) is the starting point for resisting heeling. Catamarans and iceboats have a wide stance that makes them resistant to heeling. Additional measures for trimming a sailing craft to control heeling include:
