Scupper plugs might not be the most exciting part of kayaking but, like most things that plug a hole in the bottom of your kayak, they are fairly vital. Similar to every other part of your kayak, scupper plugs will need to be maintained and occasionally replaced.

To help out, we’ve put together this guide detailing what your scupper plugs do and which ones are the best on the market.

Scupper Plugs: What Are They?

Scupper plugs are generally little rubber bungs that are designed to plug the “scupper holes” in the bottom of sit-on kayaks. All kayaks are prone to end up with water in their internal spaces.

It can come from waves splashing over the side, rain, or even backsplash from your own paddle. Scupper holes are a convenient way of draining that water out of your kayak before the weight of it makes you more likely to capsize.

Scupper plugs are designed to fit certain widths of scupper hole, so before purchasing replacement ones you should make sure you know which size your kayak needs.

Why Are They Important?

Scupper plugs are important because they stop water from moving back up through the scupper holes.

If the water you are paddling in is particularly choppy, or if your kayak is weighed down enough, then water can start to come up through the supper holes and into the kayak.

The purpose of your scupper plugs is to prevent this. The downside to scupper plugs is that they are small and easy to lose, and they also wear down over time and will eventually need to be replaced.

Is Water in My Kayak Normal?

Understandably, paddlers can become a little unnerved when water starts to come into their boat. (We’ve all seen the film Titanic!) But the truth is that water getting into your kayak in small amounts is entirely normal.

If water starts coming into the kayak in large amounts then that is exactly what your scupper holes are for. Aside from scupper holes, there are other options for bailing out your kayak.

A bilge pump is a compact and easy way to conveniently remove excess water from your boat.

How to Use Your Scupper Holes

Using your scupper holes to drain excess water out of your kayak is a quite simple procedure. Maneuver yourself into a position where you can safely put down your paddle, remove the scupper plugs, and allow the water to drain out.

If water starts to backfill into your kayak then you will need to use an alternate method of drainage, such a bilge pump or bailing sponge. Check out this video for more information:
