The Yingfa 921 Mako Shark has been approved by FINA. Yingfa has been advised by FINA, that the "Modesty Panel" in the 921, will have to be removed prior to competing at FINA approved swimming meets.
The Yingfa 921 Mako Shark is made from the "Water Strider" fabric. The "Water Strider" fabric is based on microscopic boomerang fabric, that traps tiny air bubbles, allowing the swimmer to float better in the water. The fabric was utilised after the discovery made by Xuefeng Gao and Lei Jiang of the Chinese Academy of Sciences and detailed in the 4th issue of the journel , "Nature".
Mr Jiang advised "The effect is like water off a duck's back"
It is very important to have the boomerang shapes facing the way the swimmer is moving, as air gets trapped in the nose of the boomerang material and then the shape of the boomerang will effect the flow of water, moving out and towards the back of the swimmer. This will form an air cushion and therefore maintain the swimmers buoyancy.
This has allowed Yingfa to introduce the water-resistant fabric, which results in drag-reducing and introduces fast propulsion qualities
