Super-12 is our flagship 12-strand HMPE (UHMWPE) rope, engineered for applications where maximum strength is required at minimal weight. Manufactured using Stealth Fibre®, this single-braid rope floats, resists abrasion and chemicals, and delivers outstanding strength-to-weight performance. Ideal for winches, towing, lifting, mooring and halyards in demanding marine and industrial environments.
Super-12 is a high performance 12-strand HMPE (UHMWPE) rope manufactured using Southern Ropes’ Stealth Fibre®. Designed for demanding marine and industrial applications, it delivers an exceptional strength-to-weight ratio, up to 15 times stronger than steel by weight, while remaining lightweight and buoyant. The heat treated single braid construction provides low stretch, low creep and consistent performance in both wet and dry conditions.
A durable polyurethane coating provides excellent abrasion resistance and UV protection, allowing Super-12 to perform reliably in harsh marine and industrial environments. Hydrophobic fibres prevent water absorption, maintaining predictable handling and performance throughout its service life.
Super-12 is easy to splice and resists kinking, with minimal recoil to improve safety and efficiency during operation. From offshore winch lines and tug applications to sailing halyards and heavy lifting, Super-12 is a proven HMPE rope solution for operators who demand strength, reliability and control.
