Kayak Scupper Plugs: What Are They? Do You Need Them?

If you’re a kayaker, then you know that water can come in through the scupper holes, so you need scupper plugs to keep too much water from coming in and sinking your kayak.

That’s why it’s important to have kayak scupper plugs with you on your next kayaking trip.

In this guide, we will teach you everything you need to know about kayak plugs, including what they are, how to use them, and why they’re so important.

What Are Kayak Scupper Plugs?

Kayak scupper plugs insert into the scupper holes of your kayak to keep water from splashing in.

Kayak scupper plugs are simply plugs that fit into the scupper holes of your kayak to help to keep water from coming into your kayak and sinking it.

They’re usually made of rubber or foam and come in different sizes to fit different kayaks.

Are Scupper Plugs Necessary?

So, do kayaks need scupper plugs?

Yes, kayak scupper plugs are necessary if your kayak has scupper holes because they prevent your kayak from filling up with water and sinking.

Some kayaks have scupper holes in them, which allow water to drain off the deck when the kayak is at a standstill, which is common for sit-on-top kayaks.

If you’ve got a sit-on-top kayak or a kayak with scupper holes, then kayak plugs are going to be especially important in rough waters when waves can come crashing into your kayak and fill it up with water.

They’re also good for kayaking in cold weather, as it’ll keep the cold water from coming into your kayak’s deck.

So, if you’re planning on kayaking in rough waters, rapids, or whitewater, be sure to bring along some kayak scupper plugs.

How to Use Scupper Plugs

Kayak Scupper Plug Sets
How to use scupper plugs is easy: just insert them into your kayak holes until snug, and you’re ready to go!

To use kayak scupper plugs, simply insert them into the scupper holes of your kayak.

Make sure that they are tight and snug so that no water can get through.

You may need to experiment with different sizes and types of plugs to find what works best for your kayak.

Scupper Plugs Vs Kayak Plugs

These two terms are the same thing. Because the holes in your kayak are called scupper holes, then the plugs you insert into the holes are called scupper plugs.

Some folks use the term kayak plugs instead, but there’s no difference in the meaning.

DIY Scupper Plugs

Creating homemade scupper plugs is easy and also a great way to get a custom-fit kayak plug for your yak.

The solution we like best is golf ball scupper plugs. Follow these steps:

  • Start by gathering some foam practice golf balls, paracord, and a pack of metal washers.
  • Drill a hole through the center of each foam golf ball.
  • Thread the paracord through the hole you drilled in the previous step.
  • Slide a metal washer under through one end of the paracord and tie a knot at that end. That washer will help to keep the knot from sliding out of the homemade kayak plug.
  • Tie another knot on the opposite side, then leave some additional length of paracord so you have something to pull on when inserting and removing your homemade scupper plugs.

You can also swap out the golf balls in these instructions for rubber stoppers, but make sure to measure your kayak’s scupper holes and get the right size rubber stoppers.

Kayak Scupper Valves

A great alternative to kayak scupper plugs is scupper valves.

These are essentially one-way plugs that allow water that splashes into a kayak to drain out of the scupper holes while keeping stopping water from splashing up through those same holes, which is very convenient.

Not all kayak models are compatible with scupper valves, so you’ll need to check your make and model to see what’s available.
