Abstract: A mounting system made to hold secure a custom insert device and be attached securely to a water sport board or vessel by an adhesive layer. The purpose of the insert device holding mount is to provide a small, lightweight, durable, reliable and convenient electronic device holder that can be unobtrusively attached to a water sport board or vessel and endure rough water environments and conditions. Our patent application includes our primary insert device as a water resistant time piece device, yet we plan to design a variety of insert devices with different functions for the benefit of the users. The device holding mount will be made of a soft, yet rigid water and weather resistant material. The material we will use is EVA foam, which is a type of polyethylene foam material. This EVA material is commonly used as a durable padding material in a wide variety of products.
