ILCA Kicker/Vang System
This year, an entirely new ILCA vang system makes its debut. All three 
components are upgrades from our existing system that remains the Class 
standard after more than 20 years. Here are some keys to the improved 
performance sailors will experience. 
The Upper block is now a 25mm Fly block with stainless balls and a 
unique pin shaped and angled to remain in place even under zero tension.
The middle double block is in fact a Zircon fiddle block with a unique twist (we 
call it the ‘twiddle’ in Pewaukee). Its slim shape slides easily along the purchase 
system it inhabits, to remain upright where conventional double blocks tip twist 
or tangle. A fiddle is a better choice where the line moves in uneven sequence 
around the two Zircon sheaves. 
The Fly bottom unit is also quite distinctive. 
Every sheave is larger diameter for more power and wider for less friction, so 
the unit will better enable today’s increased vang loads. And yet, by rendering it 
of our proven Carbo nylon-reinforced composite material, the unit is 21% lighter 
than our current stainless version. The whole unit is a bit more aero friendly to 
our eye and shouldn’t foul the cunningham or outhaul controls. All sheaves are 
Harken Fly with stainless bearings running in stainless races. The last turn 
before the micro Cammatic is a lightweight stainless ferrule which replaces the 
fairlead in earlier designs. The cleating angle has been made to match our 
existing standard but there’s a wedge in there for those who would like to 
experiment. The system’s design anticipates that sailors may wish to remove 
some system purchase to reduce the amount of line in the cockpit. The system 
enables this and easily converts from 15:1 to 12:1—and back again.
