Key Features & Advantages
UV Resistant & Anti-Corrosion Material
UV-proof and anti-corrosion compounds are built into the vinyl, not coatings. Protects in sun and storms.
Heavy-Duty Single-Piece Construction
Eco-friendly PVC with even wall thickness for strength and durability. One-piece design with ribs for abrasion resistance.
100% Unit Tested Before Shipping
Every fender is 100% tested with 24+ hour inflation and water tank leakage checks before packing.
Twin-Eye Dual Orientation Rigging
Dual reinforced eyelets allow vertical or horizontal use for flexible dock protection.
Needle Valve for Quick Inflation
Precision needle valve enables easy inflation and deflation with a standard pump, no tools needed.
Comprehensive Size Range G0 — G5
From dinghies to mega yachts, our range covers all vessel types. Suitable for trailered boats or permanent moorings.
Engineered for Marine Protection
360° Hull & Dock Defense System
Our vinyl inflatable fenders create a complete protective barrier between your vessel and hard dock surfaces — covering the most vulnerable contact points during every docking maneuver, whether in calm marinas or rough weather.
- Prevents hull scratches, gelcoat cracks, and paint damage on contact
- Absorbs shock from wave action, wind drift, and surging water
- Works vertically or horizontally to match any mooring configuration
- Maintains dock aesthetics with a clean, professional appearance
- Lightweight and easy to reposition by a single crew member
Marine-Grade Vinyl That Goes the Distance
Not all fenders are created equal. We formulate our vinyl specifically for the extremes of the marine environment — from blazing sun and saltwater spray to repeated compression against concrete walls and wooden pilings.
- UV-stabilized compound resists color fading and surface cracking
- Anti-corrosion formula maintains a smooth, clean appearance season after season
- Crush-resistant wall construction rebounds to shape after heavy impact
- Molded-in ribs provide extra strength and superior abrasion resistance
- Lightweight one-piece design makes relocation, storage, and deployment effortless
