Nautilus is an ancient shelled sea creature that survived centuries of evolution and still exist in our today’s deepest ocean. We hope our craft is futuristic and evolutionary in design as compared to normal watercrafts. This battery-operated watercraft can speed on water surface or partially submerged. Its main body is constructed out of a recycled plastic bottle and its wings are carved out of high density foam. The buoyancy of the craft can be regulated by shifting the sand to the desired position in its main body.
