The sailboat is propelled by the dynamic lift that the wind produces between the two sides of the sail, like the wing of an airplane. Added to the work of the keel, duly calculated according to its armature, which avoids drift, makes the vessel obey the command of its commander.

  The kayak is a vessel that allows the rower to choose  their own way, relying only on their physical ability and being able to contemplate what lies ahead, reaching any point where there is water.
