What Is a Scupper on a Kayak: A Complete Guide

If you are new to the world of kayaking, you may have come across the term “scupper” and wondered what it means. Scuppers play an essential role in the design and functionality of a kayak. In this article, we will explore what a scupper is, its purpose, and answer some frequently asked questions about this crucial feature.

What is a Scupper?

A scupper is a small hole or opening found on the deck or hull of a kayak. These holes are strategically placed and serve several purposes. They are designed to allow water to drain out of the kayak, preventing it from pooling and making the kayak unstable. Scuppers also provide self-bailing capabilities, ensuring that any water that enters the kayak through waves or splashes is quickly and efficiently drained out.

Purpose of Scuppers:

1. Drainage: The primary purpose of scuppers is to facilitate water drainage. When you paddle through rough waters or encounter waves, water can enter your kayak. Without scuppers, this water would accumulate, making your kayak heavy and unstable. Scuppers allow the water to drain out, maintaining the stability and buoyancy of your kayak.

2. Self-Bailing: Scuppers also enable self-bailing, which is the ability of a kayak to automatically drain water that enters the cockpit. This feature is particularly useful in situations where you are likely to get wet, such as whitewater kayaking or sea kayaking. Self-bailing kayaks ensure that you stay dry and comfortable, even in challenging conditions.

3. Preventing Capsizing: By allowing water to drain out, scuppers reduce the risk of capsizing. If water were to accumulate in your kayak, it would increase its weight, making it more prone to tipping over. Scuppers help maintain the kayak’s stability by quickly removing any water that enters.

Frequently Asked Questions about Scuppers:

1. Do all kayaks have scuppers?
Not all kayaks have scuppers. Some recreational kayaks, particularly sit-in kayaks, may not have scuppers as they have a sealed cockpit design. However, most sit-on-top kayaks and specialized kayaks for rough waters will have scuppers.

2. How many scuppers does a kayak have?
The number of scuppers on a kayak can vary based on the design, but typically, sit-on-top kayaks have multiple scuppers. A kayak may have four, six, or more scuppers, depending on its size and intended use.

3. Can scuppers get clogged?
Yes, scuppers can get clogged with debris such as leaves, twigs, or sand. It is essential to periodically check and clean your scuppers to ensure proper drainage. A clogged scupper can hinder water drainage and compromise the stability of your kayak.

4. Can I modify or add scuppers to my kayak?
While it is possible to modify or add scuppers to a kayak, it is recommended to consult with a professional or kayak manufacturer before making any alterations. Adding scuppers in the wrong location or without proper knowledge can negatively impact the kayak’s performance.


Scuppers are an integral part of kayak design, providing drainage and self-bailing capabilities. Their presence ensures that any water that enters the kayak is quickly and efficiently drained out, maintaining stability and preventing capsizing. While not all kayaks have scuppers, they are commonly found in sit-on-top kayaks and specialized models for rough waters. Regular maintenance, such as cleaning and checking for clogs, is necessary to ensure the scuppers function correctly. With scuppers, you can enjoy a dry and stable kayaking experience even in challenging conditions.
