Physics: surfboard motion

In our project, we produced small-modeled surfboards made from polyester. The aim of the experiment was to predict and check which type of surfboard moves faster in a water tray due to waves oscillations pushing them. The proposal was to produce surfboards with different number of fins, and different width and length in order to check how these factors affect the surfboard motion
5 surfboards were produced:
• A surfboard with with no fins was made in order be the control model for the experiment, where it has no alterations in it
• A surfboard with three fins
• A surfboard with a thicker width and 2 fins
• A surfboard with a thicker length and 1 fin
The ideal number of fins for a surfboard is three. The fins are essential to give speed and direction to it. So the surfboard with three fins, and two fins are predicted to move faster than the surfboard with one fin
The width and length of a surfboard is crucial to give It speed. Therefore the surfboard with a higher value for thickness and length is predicted to move faster than the others.
