The purpose of this research is to propose a stream line that can do swimming at a certain depth and can combine less drag. Acquiring a low resistance streamline in swimming competition is very important for performance and efficient swimming. Also, in the diving competition, there is a competition competing for distances where you can stop breathing and swim horizontally in the water, breathing is stopped. It is important to promote a certain depth to earn swimming distance. Because when it swims in the position close to the water surface, the wave-making resistance works. It is necessary to balance both the forward tilted posture and the small drag. Therefore, in this research, using various 3DCAD software, various streamline forms were created and flow analysis around the streamline model was performed with general-purpose thermal fluid analysis software STAR-CCM+. Buoyancy and lift force are balanced, I found a streamline with less drag
