What's Changed on the New Harken ILCA Vang/Kicker Base?

Those who've been sailing an ILCA for a while will know the Harken kicker has barely changed in the last twenty years. But for 2026, Harken's redesigned the whole lower assembly, and it's already seeing a lot of positive response from dinghy sailors.

If you've ever come into the windward mark with your kicker locked solid, the new Harken ILCA vang was built with you in mind. We’re covering what’s changed and why, as well as the feedback the new Harken kicker base unit is getting.

Quick note: Vang and kicker are just two names for the same control, the line and block system that stops your boom from skying when you ease the mainsheet downwind.

Why Harken Redesigned the Vang/Kicker

The old Harken lower assembly had been the class standard for over two decades, and for most of that time it did the job well enough. But ILCA sailing has changed. Sailors are physically stronger, training more systematically, and pulling considerably harder on their controls than the class ever anticipated when the original design was signed off. Vang loads in modern racing are significantly higher than they were when stainless steel made sense as the default material, and the old unit was starting to struggle under them.

Two things in particular were letting sailors down. The cleat was notoriously difficult to release under heavy load, which mattered most at the worst possible moments in a race. And the control line routing geometry meant snagging was a persistent issue for a lot of sailors, regardless of how carefully they rigged the boat.

This new Harken ILCA vang is a proper rebuild with different material, bigger sheaves, a reworked cleat mechanism, and geometry that remedies the snagging problem.

What's Changed on the New Harken Laser Kicker

Plenty of sailors still call this boat the Laser out of habit, even though it's been ILCA for years, so if you're hunting for a Harken Laser kicker upgrade, this is it. Here's what's actually different from the old assembly.

The new kicker base unit is built from Carbo Nylon-Reinforced composite rather than stainless steel, cutting weight by 21%. The sheaves are larger in diameter and wider than before, running on stainless bearings in stainless races. That cuts friction noticeably when you're grinding the kicker on hard, which matters most in a breeze when you're hiking flat out and need to dump power fast.

One persistent gripe with the old assembly, and with some rivals too, was control lines snagging on the unit mid-tack. The redesign moves the turning points further from the mast, keeping your Cunningham and outhaul lines running clear when you need them most.

The cleat mechanism has been reworked too, so uncleating the kicker under load is now much easier. Out goes the old fairlead, in comes a stainless ferrule for a smoother last turn into the cleat. The cleat arm flips to face you with barely a tug on the control line, rather than you having to hunt for the angle coming into the mark. 

The default cleating angle suits most sailors out of the box, but there's a wedge included if you want to adjust it. The purchase converts between 15:1 and 12:1 too, so you can manage how much line ends up running through the cockpit.

The vang key, which attaches the whole assembly to the boom tang, could work loose or fall out when the system went slack on the old unit. The redesigned, forged stainless steel key has a unique profile that holds itself in position under zero tension, so it stays put between tacks without needing to be checked.

Worth noting that it's slightly trickier to remove the vang key after sailing with the sail still attached or the vang under tension, so it's worth releasing the vang fully before trying to pull it.

What Sailors Think About Harken’s new ILCA Kicker Base

When the new system first appeared in Harken's 2026 catalogue, sailors on the forums picked up on it quickly. The swap from the old bullseye cleat to a proper block on the swivel cleat was immediately singled out as a long-overdue improvement.

There was also genuine interest in the new vang key design, with one experienced forum member describing it as something they'd want on their own boat. The same sailor noted that the twisted fiddle middle block, with its internal 45-degree twist, is a genuine first in class hardware. Nothing else on the market does what it does.

The new Harken kicker system was also shown publicly at the RYA Dinghy and Watersports Show 2026 by Harken UK's David Brown, where it drew significant interest from the fleet.

ILCA Masters sailor Max Hunt put the new assembly through six days of competition and two days of training, finding the new lower assembly considerably easier to uncleat under load than the old Harken unit. Across eight days on the water, he had no control line snagging at all.

What You’ll Need

The new Harken kicker base unit is sold as a base unit only. It attaches to your ILCA lower mast with a pin and ring or a quick-release pin, and ships ready to rig with either a 15:1 or 12:1 purchase configuration.

It's designed to work as part of a complete system alongside Harken's new 25mm Fly high load top block and Zircon Twisted Fiddle middle block, all three of which were redesigned together. You can run the base unit with existing top and middle blocks if you're upgrading in stages, but the full system is what it was designed around.

If your downhaul and outhaul are also due a refresh, the ILCA Harken Power Pack covers both in one go.

Is the New Harken Vang Worth the Upgrade?

If your current kicker is hard to release under load, or you've had lines snagging on the lower assembly mid-race, this redesign addresses both directly. 

If your existing kicker is working fine and you're not chasing marginal gains, there's no rush. The old version remains class legal and plenty of sailors will get more seasons out of it yet. The previous generation Harken Laser kicker base unit is now available at a reduced price if you're looking for a solid upgrade without the premium.
