Ronstan ILCA Vang/Kicker Base Unit The New Benchmark in Design and Performance Upgrade your ILCA with the Ronstan Lower Vang Unit, widely recognised as the new standard in design and competitive performance. Thoroughly tested on the water by leading ILCA® sailors, this base unit features an optimised geometry engineered to minimise line chafe and drastically reduce friction. This refined alignment translates directly into a distinct purchase advantage, giving you maximum power when you need to pull on the kicker in a heavy breeze. It also ensures incredibly intuitive cleating and releasing, allowing you to stay in full control and play the vang effortlessly from any angle—whether you are tucked inboard navigating a mark rounding or fully hiked out upwind. At the core of this system is the primary purchase sheave, which utilises Ronstan's high-load, ultra-low friction stainless steel HHL sheave. Additionally, the geometry of the cleat arm pivot point has been strategically positioned as close to the clevis pin attachment as possible. This smart design choice minimises leverage and significantly reduces the stress placed on your mast attachment point, protecting your rig from long-term fatigue. (Note: This is an officially licensed ILCA® part, available for purchase through ILCA® approved builders and dealers.)
