The growing new sport of hydrotouring (aka sea hiking) involves swimming long-distances in open water, often with a monofin. Currently, all swim fins are hard to put on, cumbersome to travel with, and painful to wear for longer than ten minutes. The goal for my capstone is to create an innovative monofin design by addressing needs of adjustability, durability, safety, travel and comfort. While swimming with a monofin, energy is generated through the whole body and directed to the fin through the ankles, causing pain and discomfort in a matter of minutes. My approach is to extend the fin so that it acts more like a brace for the feet, making energy transfer to the fin more efficiently and putting less strain on the ankles.
