10:1 Downhaul System - Allen 30mm High Load Blocks

10:1 Downhaul System, using the amazing Allen 30mm high load blocks for optimum performance.   This top of the range downhaul is fitted our premium Robline Polytech line which has a blended Technora®/Polyester cover for excellent durability and grip, and a Dyneema® SK78 core providing greater longevity especially for the highly loaded downhaul where the cleat causes wear, and excellent grip in the hands.

Primary line is 4mm SK78 Dyneema.

Choose the secondary line colour and length that you want.  PLEASE NOTE that this 10:1 system is only intended for the ILCA7 using the Standard MKII sail.  It is not needed for the ILCA4 (4.7) or ILCA6 (Radial) rigs where the 6:1 and 8:1 systems are perfect.
