Effects of Water Density on Drag
Wrong: A diver in a vertical position must displace a large amount of water to move.
Right: A horizontal position requires much less water displacement, making swimming easier.
Drag is any resistance to movement. We encounter drag when we move on land because we constantly displace air. But air isn't very dense, and its drag is rarely noticeable.
Drag is increased in the water because of the increased density. To minimize drag and make swimming easier, it's important to streamline yourself. This decreases the effort required to move in the water and makes your fin kicks more efficient.
The most important step to take in streamlining yourself is positioning your body in a horizontal position. This decreases the amount of water that is displaced as you swim. To further streamline yourself, secure all hoses and equipment close to your body.
