Efficient Self-Draining Function:
The innovative self-draining mechanism automatically drains the accumulated water on the boat, preventing water accumulation and ensuring that the cabin is dry and safe.

Smooth Function:
The ball valve operates smoothly, allowing water to flow out freely while preventing debris from entering, protecting the hull from potential damage.

Multifunctional Features:
The boat self-bailing ball scupper valve not only acts as a drain valve, but also has a check valve function, which can prevent water from flowing back into the boat even in severe sea conditions.
