Ready to get that water out? Let’s walk through exactly how to drain your sit-on-top kayak step by step.
“`htmlKeeping Your Sit-On-Top Kayak Water-Free
So, you’ve had a fantastic day out on the water. Whether you were practicing your paddling skills, fishing, or just enjoying a leisurely cruise, a bit of water inside your sit-on-top kayak is perfectly normal. In fact, it’s designed that way! Now, before you store your trusty vessel, you’ll want to get that water out. This simple maintenance step ensures your kayak stays light, dry, and ready for your next adventure.
Why bother draining it? Well, a waterlogged kayak is heavier, harder to handle, and can lead to mildew or unpleasant odors over time. Nobody wants that! We’ve found that most paddlers can get their kayak drained in just a few minutes. Let’s dive into how you can do it efficiently.
Locating Your Kayak’s Drainage Points
Your sit-on-top kayak has built-in features to help you with this. The most common methods involve using its drain holes or scupper plugs. Think of these as little helpers designed to let water escape naturally.
Understanding Scupper Plugs
Many sit-on-top kayaks come equipped with scupper holes. These are essentially openings in the hull that allow water to drain out. Sometimes, manufacturers include scupper plugs. These are small stoppers you can insert into the scupper holes. Their main purpose is to keep water *out* while you’re paddling. However, they also play a role in draining the kayak after you’re done.
When you want to drain your kayak, you’ll often need to remove these plugs. We’ve found that some paddlers prefer to leave them out entirely when they know they’ll be paddling in calm waters and want easy drainage. Others prefer to keep them in for protection and remove them only when needed for draining. It really comes down to your paddling style and conditions.
Identifying the Drain Holes
Beyond scupper plugs, some kayaks might have dedicated drain holes. These are typically located on the lowest points of the hull. Their job is to let out any accumulated water. You’ll want to make sure these aren’t clogged. We’ve seen many a paddler frustrated by slow drainage, only to find a piece of seaweed or sand blocking the way!
The Step-by-Step Draining Process
Getting the water out is usually a straightforward process. It requires minimal tools and just a bit of know-how. You’ll want to have your kayak on a level surface, ideally slightly tilted, to help gravity do its work.
Preparation is Key
Before you start, take a moment to gather what you might need. While often simple, having a towel or sponge handy can be useful for those last few puddles. If you’re using scupper plugs, make sure you know where you stored them so they don’t get lost.
Positioning Your Kayak
The best way to drain your kayak is to position it so the drain holes or scupper holes are at the lowest points. Often, this means placing your kayak on a slight incline. If you’re on a dock or a ramp, this is usually easy to achieve. If you’re on flat ground, you might need to prop up one end slightly. We’ve found that even a small tilt can make a big difference in how quickly the water evacuates. Just be sure your kayak is stable!
Removing Scupper Plugs (If Applicable)
If your kayak uses scupper plugs, this is the time to remove them. They might be a simple push-in type, or they could have a small tab or lanyard. Gently pull them out. Don’t force them, as this could damage the plug or the kayak. If they seem stuck, a little wiggle might be all that’s needed.
Once removed, place them somewhere safe. You don’t want to leave them behind on the beach! Many paddlers keep a small dry bag or a dedicated compartment for these small but important pieces.
Clearing the Scupper Holes and Drain Points
This is a critical step. Debris can easily get lodged in the scupper holes or drain ports. Sand, small pebbles, leaves, or even stray fishing line can create blockages. You’ll want to visually inspect each opening. If you see anything blocking the hole, carefully remove it.
A quick way to check is to poke a finger or a small, blunt object (like a pen cap) into the hole. You should feel and see that it’s clear. We recommend doing this every time you drain your kayak. This ensures optimal drainage and prevents potential damage from water sitting in unexpected places.
Letting the Water Flow
With the scupper plugs removed and the holes clear, the water should begin to drain on its own. Gravity will pull the water down and out through the openings. You might hear a little gurgling sound, which is perfectly normal. This is the water finding its way out.
Give your kayak some time to drain completely. The amount of water will depend on how much splashed in during your paddle. If you notice any stubborn puddles that aren’t draining, you can use a sponge or a towel to soak them up. Some kayaks also have small built-in “self-bailing” features that help funnel the last bits of water towards the scuppers.
Final Touches and Drying
Once the bulk of the water is out, you’ll want to do a final sweep. Use your towel or sponge to wipe down any remaining moisture inside the cockpit area and on the deck. This prevents water from pooling and evaporating slowly.
Allowing your kayak to air dry completely before storage is a great practice. This helps prevent mold and mildew growth. If possible, leave the hatch covers open or removed for a while in a dry, well-ventilated area. We found that a little extra drying time can significantly extend the life and preserve the condition of your kayak.

Troubleshooting Common Drainage Issues
What if the water just isn’t draining as quickly as you’d expect? Don’t panic! Most issues are easily fixed.
Stubborn Debris
Sometimes, debris can be lodged deeper than you can easily reach. In these cases, a gentle stream of water from a hose can often dislodge it. Be careful not to spray water directly into any sensitive areas of your kayak.
Clogged Hull Channels
The channels that direct water to the scuppers can also get blocked. If you suspect this is the case, you might need to use a flexible tool or even a stiff brush to clear them out. Many kayak manufacturers offer cleaning tools specifically for this purpose.
Reinstalling Scupper Plugs
Once your kayak is dry and you’re ready to store it or transport it, you’ll likely want to put your scupper plugs back in. This keeps the inside clean and prevents unwanted critters from making a home in your kayak. Ensure they fit snugly.
A Quick Checklist for Easy Draining
Here’s a handy checklist to make sure you don’t miss a step:
- Position kayak on a slight incline.
- Remove all scupper plugs.
- Visually inspect and clear scupper holes.
- Check and clear any other drain ports.
- Allow ample time for water to drain.
- Wipe down and air dry thoroughly.
Conclusion
You’ve learned how simple it is to drain water from your sit-on-top kayak. By understanding your scupper plugs and drain holes, you can keep your kayak light and prevent mildew. Remember to always position your kayak correctly and clear any debris from the drainage points. This quick maintenance ensures your kayak is always ready for your next adventure. The next time you finish a paddle, take a few minutes to drain your kayak thoroughly; your future self will thank you!
Frequently Asked Questions
How often should I drain my sit-on-top kayak?
You should aim to drain your kayak after every paddling session. This prevents water from sitting and potentially causing mildew or odors. It also keeps your kayak lighter for easier handling and storage.
What if my scupper plugs are stuck?
If your scupper plugs are stuck, avoid forcing them. Try gently wiggling them back and forth. Sometimes, a little bit of water or a mild lubricant (ensure it’s kayak-safe) can help them slide out more easily.
Can I leave my scupper plugs out all the time?
Leaving scupper plugs out can allow for easier drainage. However, if you paddle in rough water, they can help prevent water from coming *into* your kayak. We’ve found many paddlers remove them for calm water use and reinsert them for choppier conditions.
My kayak still has puddles after draining. What’s wrong?
Even after draining, some small puddles might remain. Use a sponge or towel to wipe these up. If you have persistent pooling, check if the channels leading to the scuppers are clear of any blockages.
Is it okay to store my kayak with a little bit of water left inside?
It’s best practice to get as much water out as possible before storing your kayak. Storing it wet can lead to mold, mildew, and unpleasant smells. Allowing it to air dry completely before putting it away will preserve its condition.
