Anyone aiming to sail an ILCA (formerly Laser) at the highest level knows that the kicker, or vang, plays a decisive role in control, acceleration, and upwind performance. With the 1252.ILCA Harken ILCA Vang Lower Unit, you get the central power component of the new ILCA vang system – more powerful, lighter, and more efficient than previous generations.
Maximum Control with Minimal Friction
The 1252.ILCA Lower Unit is the heart of the lower vang system. Compared to earlier stainless-steel versions, this unit is 21% lighter, as it is manufactured from Harken’s proven Carbo nylon composite material.
This means for you:
-
Less weight in the cockpit
-
Faster, more direct response
-
Greater efficiency under high loads
The larger sheave diameters provide increased mechanical advantage and reduced friction, which becomes especially noticeable in strong winds or under heavy vang loads.
Technical Highlights of the 1252.ILCA
All sheaves run on Harken Fly stainless steel ball bearings in stainless steel races, ensuring consistently low-friction performance and long-term durability.
Smart Design for Racing Sailors
The H1252.ILCA Vang Lower Unit was specifically developed for the new ILCA system and replaces previous stainless-steel assemblies. The final turning point combines Fly sheaves with a lightweight stainless-steel swivel, keeping the system stable and properly aligned under load.
Another key advantage:
The system is designed to allow sailors to convert from a 15:1 to a 12:1 purchase ratio – and back again – when desired. This enables fine-tuning of the setup according to sailor weight, wind conditions, and personal preference.
The Harken ILCA Vang Lower Unit is not just a replacement part, but a true performance upgrade. Lighter, stronger, and more efficient than previous systems, it delivers maximum rig control in both light and heavy air.
If you value precise trimming, durable components, and modern ILCA technology, the H1252.ILCA is the right choice for your setup.
