Scupper holes, found in sit-on-top kayaks, are designed as a safety feature to drain water out of the kayak, from top to bottom, which keeps you from sitting in a puddle or even worse, making your kayak a bathtub full of water prone to capsizing. The intent of scupper plugs, designed to fit in these holes, is to keep water from coming in, which can happen in choppy water or when there is significant enough weight in the kayak to push the hull deep enough in the water to force water into the cockpit.
Remember: A Little Water Is Normal
Customers always ask me about water coming in through their scupper plugs. Don’t be alarmed, the incoming water doesn’t mean your boat is going to sink. Regardless of your kayak’s capacity and scupper plug usage, it’s perfectly normal for water to enter the boat one way or another. However, excessive water – whether it’s from spray, paddle splash, waves, or entering and exiting your kayak – consistently in your boat can become bothersome.
Bothered By Excessive Water? Carry A Sponge Or Bilge Pump
If you prefer not to remove your scupper plugs to drain water in your kayak, simply use a sponge or bilge pump. It’s never a bad idea to carry one or both of those products with you for safety and convenience. The truth is, water will always find its way into your boat. It’s just a matter of personal choice. Most people don’t like to sit in a pool of water while others don’t mind getting a little wet. If you do have some water entering your boat but want the convenience of it draining back out, consider plugging your scuppers closest to your seat and leave the ones by your feet open. Another option is to find a “drier” kayak or one that is better suited for your weight.
