The external aesthetics of a product is a critical factor that attracts customers and forces them to own the product. The exterior style can communicate the category and type of the product with the customers and it can create a feel on them to own it. Usability of a product is another factor which satisfies the customer over the product. Thus the external aesthetics as well as usability have a strong influence on the success of a product. In this project an attempt is made to enhance the exterior style as well as usability of Personal Water Craft or else called as Water Bike. Manufacturers are spending huge amount for research and development of new ideas and innovations in this field. So the design of Personal Water Craft focusing on aesthetics and ergonomics is valid in present context.
