The sail on the sailboat helps move the boat when the wind energy and force are greater than the waters energy and friction.
In modern sailboats they have a motor in case the wind is not stronger then the water.
Forces and motion of the sailboat.
The forces acted on the sailboat are the sails force, the boats course, the winds force and direction, and the force and friction of the water
The motions of the sailboat is the waters friction, the floatation of the boat, and the wind direction.
