Water skis are specialized equipment designed for gliding across the surface of water while being towed by a boat. They are typically made of lightweight materials like fiberglass or plastic and come in pairs, with one ski for each foot. The skier stands on the skis, holding onto a tow rope connected to the boat, which pulls them along. To use water skis, the skier starts in the water, holding the rope and keeping the skis close together. Once the boat accelerates, the skier rises up on the skis and balances to enjoy the ride. Water skiing is a popular recreational activity enjoyed by many during the summer months.
