1. Why Fender Size Matters

Selecting the correct fender size ensures full hull protection during docking, rafting, or mooring. Effective sizing accounts for your yacht’s length, displacement, and mooring context—especially in high-traffic marinas or challenging conditions.

Sizing Rule of Thumb:

  • Cylindrical fenders: ≈ 1 inch (25 mm) of diameter per 4–5 feet (1.2–1.5 m) of vessel length.

  • Spherical fenders: ≈ 2 inches (50 mm) diameter per 4–5 feet—useful for bow corners or beam ends.

This guideline may need adjustments for heavier yachts or more extreme mooring scenarios.

3. Placement & Quantity Recommendations

  • Use at least one fender per 10 ft (3 m) of waterline, with a minimum of three on smaller yachts for secure coverage.

  • Mount fenders so their middle just reaches the waterline. Too low—risk of marine growth; too high—risk riding up and impact loss.

  • For horizontal deployment on larger cylindrical models (C84+), be sure to use a Long Side Cover to protect the valve and maintain form.

4. Why Fendertex Outperforms Traditional Fenders

  • Superior strength-to-weight ratio: Light enough for effortless handling but engineered for high-impact protection.

  • Compact storage: Collapses to just 5–10% of inflated volume—critical space-saving advantage onboard.

  • Enhanced fit: Multiple shapes (cylindrical, spherical, tandem) and sizes meet diverse vessel configurations and docking scenarios.

  • Customization: Logo, color, and cover options align with yacht branding.
