This ILCA mast loop complete combines a PolarWave lightweight 29 mm block with a pre-spliced, self-tightening Dyneema mast loop for a clean and efficient Cunningham or outhaul system.

The 29 mm PolarWave block is paired with a professionally spliced 4 mm Marlow Dyneema® SK78 line, allowing the block to automatically stay in the correct position under load. For outhaul use, the mast loop is positioned above the gooseneck fitting. For Cunningham use, it sits below the vang tang. No metal shackles are required, keeping friction to a minimum and the mast area clean and uncluttered.

Designed for Laser 4.7, Radial and Standard, and compatible with ILCA 4, ILCA 6 and ILCA 7.
