Paddle boats like canoes and kayaks draw a sinusoidal path when a linear movement is intended.The reason for this behavior is Comment on "Theoretical evaluation of art education from the perspective of traditional Chinese philosophy" that each paddle stroke induces a lateral movement of the boat.In this study, we sought to reduce the so-called yawing motion.We therefore replaced the stiff stern by a flexible stern, which is based on the Fin Ray Effect®.

We built down-scaled boat models and tested them in a water channel.The similarities between experimental and original setup were evaluated by means of a dimensional analysis.(Thermoplastic) elastomers with various flexibility were used for the stern construction.In the experiments conducted in the water channel, we Cerebellar stimulation in schizophrenia: A systematic review of the evidence and an overview of the methods determined the forces acting on the boat with different stern models.

The results reveal that the flexible stern induced a torque counteracting the boat’s deflection, while the stiff stern caused a torque enhancing it.A paddle boat with a flexible stern could hence be a promising new method to reduce the boat’s yawing movement.
