Rabud SeaScuppers: Purpose-Built Marine Drain Solutions
Rabud, Inc. has been engineering marine deck hardware since 1976, and their entry into the scuppers and drains category was driven by a simple but critical demand from the boating industry: better, faster deck drainage. The result was the Rabud SeaScupper — a transom drain scupper engineered specifically for self-bailing decks that has become a trusted name among boat builders and offshore anglers alike.
How the Rabud SeaScupper Works
The SeaScupper's design is elegantly functional. Rabud's Sea Scupper automatically bails then seals using a solid polypropylene ball and a long-life PVC seal. When water accumulates on deck, the ball lifts and allows it to drain freely. When the boat is underway or waves threaten to push water back aboard, the ball drops and creates a watertight seal — keeping the interior dry without any manual intervention.
Materials Built for Harsh Marine Environments
Rabud doesn't cut corners on materials. Each SeaScupper features a polycarbonate housing paired with a long-life PVC gasket, and is UV-stabilized to withstand years of exposure to sun, salt, and spray. The solid polypropylene ball mechanism is non-corrosive and resistant to the kind of degradation that plagues metal or rubber alternatives over time. These aren't components you'll be replacing every season.
Two Sizes for a Wide Range of Applications
Rabud offers the SeaScupper in two sizes to accommodate different vessel configurations. The 1" Drain model fits drain tubes up to 1 inch in diameter, while the 3" Drain model accommodates drain holes up to 3 inches in diameter. Both versions are designed to retrofit most older rubber flapper-style scuppers, making them an accessible upgrade for existing boats without major modification. Mounting holes positioned at the 2, 4, 8, and 10 o'clock positions give installers flexibility during fitment.
A Direct Answer to the Boatbuilder's Problem
What sets Rabud apart in the scuppers and drains space is context: the SeaScupper wasn't designed by a generic hardware company — it was born out of real boatbuilding experience. Rabud's products are closely aligned with OEM boat manufacturing standards, and custom colors are available for builders seeking a seamless deck aesthetic. For boat owners and builders who want a self-bailing solution that truly works and is built to last, Rabud's SeaScuppers represent a focused, field-proven answer.
