The purpose of scupper plugs is to provide an optional solution for controlling water flow in a kayak's scupper holes. These plugs can be inserted into the scupper holes to prevent water from entering the cockpit, keeping it dry and enhancing stability. Scupper plugs are particularly useful in situations where you want to minimize water splashes or if you are paddling in colder conditions and want to maintain a warmer, drier interior. They offer flexibility in adjusting the level of drainage and can be easily inserted or removed as needed. Scupper plugs are designed to fit securely into the scupper holes, providing a tight seal and preventing water from accumulating inside the kayak. By using scupper plugs, you can customize your kayaking experience and ensure optimal comfort and control on the water.
