Vulcanized rubber or drop stitch materials offer the durability and rigidity needed for whitewater, heavy loads, or professional use.
TPU or vulcanized rubber are more sustainable choices compared to PVC, which is hard to recycle.
Rinse with fresh water: Remove salt, sand, and debris to prevent abrasion and corrosion.
Mild soap: Use a non-abrasive detergent for stubborn stains; avoid harsh chemicals that degrade materials.
Covers: Use UV-resistant covers when storing or leaving the boat inflated for long periods.
Shade: Park in shaded areas to minimize sun exposure during use.
Dry completely: Moisture leads to mold and mildew; air-dry before folding.
Cool, dry spaces: Avoid attics or garages with extreme temperatures.
Immediate action: Use manufacturer-provided patch kits for small holes. For larger damage, consult professionals.
Pressure gauge: Check inflation levels regularly to avoid over/under-inflation.
Reality: While Hypalon is durable, it’s not indestructible. Glued seams can fail over time, and UV exposure eventually causes degradation. Expect 15–20 years with proper care.
Reality: Well-maintained PVC boats can last 5–10 years. Regular cleaning, UV protection, and avoiding harsh conditions significantly extend their life.
Reality: High-quality glue in Hypalon boats can be durable, but welded seams (common in PVC/TPU) are stronger. Glued seams are more vulnerable to heat and chemical exposure.
The industry is shifting toward more sustainable and high-performance solutions:
Self-Healing Materials: Innovations like puncture-resistant coatings that seal small holes automatically.
Hybrid Fabrics: Combinations of TPU and PVC to balance cost and durability.
Nanocoatings: Thin layers that enhance UV and abrasion resistance without adding weight.
Eco-Friendly Alternatives: Bio-based polymers and recycled materials replacing traditional PVC.
