ILCA Mainsheet Blocks and Vang Units.
Ronstan’s ILCA® mainsheet blocks provide the perfect balance of strength, performance, and reliability Ronstan is known for. They feature a 2-stage bearing system which minimises friction and gives sailors ultimate control while trimming.
Ronstan’s ILCA® lower vang unit is the new benchmark in design and performance. Thoroughly tested on the water by leading ILCA® sailors, the vang unit features optimised geometry to minimise line chafe and friction which provides a purchase advantage, and easy cleating and releasing to stay in full control when playing the vang from any angle while inboard or hiking. The RF34108HL is a purpose designed ILCA® top vang block.
