# Best Scupper Plugs for Sit-On-Top Kayaks Source: https://kayaknest.com/best/best-scupper-plugs Updated: 2026-09-15 Publisher: Kayak Nest. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://kayaknest.com/how-we-research#our-score Scupper holes drain a sit-on-top, which is exactly what you want in surf and exactly what you do not want on a calm lake in cold weather, when they push cool water up onto the seat. Plugs let you choose. The catch is fit, since scupper diameters and taper vary between models and a plug that seals one hull will pop out of another. Materials also differ in how they behave after a season of sun. We weighed sealing across common scupper sizes, whether the plug stays seated under a loaded hull, and pull tabs or leashes that let you pull them fast. Soft tapered plugs suit paddlers who swap between calm and rough conditions. Valved plugs suit anglers who want one-way draining without fully sealing the deck. Leave scuppers open in surf, whitewater, or anywhere you expect to take water over the bow. ## Picks ### 1.
