Engineered for Marine Protection
360° Hull & Dock Defense System
Our black PVC inflatable fender creates a dependable shock buffer between your vessel and hard dock surfaces, pilings or other boats — absorbing collision impact during every docking and mooring maneuver, whether in calm marinas or active river traffic.
- Prevents hull scratches, paint peeling and dent damage on contact
- Ribbed surface distributes impact force evenly across the fender body
- Absorbs shock from wave action, wind drift and vessel-to-vessel contact
- Suitable for yachts, speedboats, fishing boats and pontoons
- Lightweight and easy to reposition by a single crew member
Marine-Grade PVC That Goes the Distance
Not all fenders are created equal. We formulate our thick marine PVC specifically for the extremes of the waterfront environment — from blazing sun and saltwater spray to repeated compression against docks and pilings in sea, lake and river settings.
- UV-resistant compound prevents surface cracking and material degradation
- Saltwater erosion resistance for long-term marine and river use
- Anti-aging formulation maintains flexibility and cushioning over time
- Adjustable air pressure tunes softness for different boat sizes
- Thick wall construction rebounds to shape after heavy impact
