Sailplan 2

DeckplanThe Sailplan is the effort or force generator – creating all the power to drive the boat through the water.Sailplan

The keel is creating its own lift force in the opposite direction, resisting the sails efforts to push the boat sideways.

The sailplan’s centre of this effort is in the geometric centre of the sailplan.

The hull’s (underbody, keel and rudders) centre of lateral resistance is in the geometric centre of the underbody of the hull.
