The Fins in this project are based on the Thresher shark. Its tail is shaped like a thresher, and the shark uses it as a weapon to stun its prey. Since this shark is an active predator, its tail should not only be used as a weapon, but also a great source of propulsion. In order to design and compare a fin to this extraordinary shark tail, a simple trapezoid was created to set a base model. Its dimensions are as follow: This fin is the base model designed to set the first data of propulsion, so that it could be compared to the shark tail. In addition, three caudal fins were design just like the shark tail, where the C (length of the middle of the fin) was maintained constant to 2.5in, but the Span was increased by 50% for each model starting
