The Antal HS guide system is designed for boats with full batten mainsails that experience high loads and compression-loading on the mainsail luff. The system’s aluminium sliders contain HS composite fibre inserts that run on aluminium track mounted on the mast. HS composite fibre is a new material that is durable over long periods of use and offers extremely low friction coefficients. The material is made from special resins strengthened with fibre and is self lubricating.
