But as a sailing ship, all the power comes from those sails. You might think to add larger sails. Unfortunately, sails do not limit your maximum power. The sail plan gets limited by the righting moment of your hull. [5] [6] As the wind heels the boat over, the hull pushes back with a righting moment.
