The design of a pool lane is both scientific and practical. A typical lane consists of a strong rope, floating discs (also called donuts), and a tension system at both ends. The rope is usually made of durable, water-resistant materials like nylon or polyester. These materials prevent the rope from sinking or wearing out quickly. The floating discs are often made of UV-stabilized plastic, which can withstand sunlight and chlorine. Their round shape and smooth surface help in absorbing waves efficiently. Some modern pool lanes even include anti-wave technology that breaks up water turbulence into smaller, harmless ripples.
