manta by Product design from spain
designer's own words:
Manta try to simulate the experience of being a stingray in snorkelling/diving activities and sets up a new way of bodyboarding. Its made of two main materials .
The harder material is made of semifloating plastic (PP) and simulate the bone of the stingray. The softer part is made from rubber and try to simulate the muscle tissue of the animal. Mixing both material it is an approach of the real anatomy and movement of the stingray.
Chest and belly are placed in the middle , allowing arms to wave side wings because of the flexible combination of the design.
You can use it underwater or taking waves.Manta would be like an extension of your body ,push and pull the wings to direct yourself trough water. It has an hydrodynamic spoiler in the nose for water flowing and several fins in its surface for better grip and direction managing.
