Performance, speed and glide have been taken to the next level with the HA1125. This high aspect foil was developed with key design input from Pete Burling, helmsman of Team New Zealand’s Americas Cup yacht (Current AC holders) and tested by legendary sailor, Jimmy Spithill.

Pete, Jimmy and Armie became friends as foiling united their search and passion for ultimate performance and glide on downwind runs. The mad scientist and these high-performance sailing gurus have collaborated to create something the likes of which has not seen before outside the Americas Cup!

At 9.8:1 it’s a true High Aspect ratio foil wing that sets the standard for glide performance, while retaining enough handling that it can be turned easily, making for an exhilarating ride.

Downwind aficionados requiring max glide performance will want to get their hands on this wing simply because it is next level!

In small surf on an 85cm mast or longer, the HS1125 can be ridden to good effect, the turning radius is surprisingly good for is high aspect ratio. The sleek, inflected tips help prevent ventilation even if a tip breaches. It’s next level pump and glide make it easy to double dip!

For experienced wingers there is no comparison. It makes tacking fun and easy as the glide gives you so much time to complete maneuvers like 360’s. Combine this with amazing upwind angles and outrageous downwind glide, as well as freakish light wind performance and the riding it just never stops!

Armstrong A+ System Questions:

1: What is the A+System? The new A+System has been developed by Armie to handle the new generation of mid to high aspect wings, which produce massive torsional leverage forces. To improve durability, longevity and performance the A+System has full width Titanium Barrel Nuts across both mast and front wing connections to lock them in position. The tail wing connection has been simplified, streamlined and strengthened and now incorporates a simple polycarbonate shim system.

2: Which parts of the A+System Foil Kit are different from the current Foil Kits? The A+System TC Fuselage is the heart of the updated kit. We have added threaded screw inserts for the new Titanium Barrel Nuts and the tail area is updated so that the tail wing now fits directly to the fuselage. A+System front foils and masts have an extra hole to accommodate the new Titanium Barrel Nuts. The screw set is updated with slightly longer screws and Titanium Barrel Nuts.

3: Will my current Kit be compatible with the A+System parts? All current HS and CF front wings, tails, fuselages and masts are compatible with the new A+System parts. Front wings and masts can be upgraded with our drilling jig kit to accept additional Barrel Nut connections. ALL current TC fuselages will accept the Barrel Nut on the front wing but not on the mast as it passes through the titanium core so it is not possible to retro drill and tap this.

4: When I buy A+System front and tail wings, will these fit my current system? Yes – And you will be able to use the new Barrel Nut system on the front wing with your current fuselage.

5: If I buy a new mast, will there be a hole that I can’t screw a bolt into? Yes, but it will not affect riding performance. The A+ system mast has an extra screw hole for A+ system screw and Barrel Nut, which is factory threaded through the Titanium Core of the TC fuselage.

6: If I buy just an A+System Fuselage are my current wings and mast upgradable? Yes, with the drilling kit it’s possible to retrofit both mast and front wings to take advantage of the A+System’s full potential.

7: If I buy just an A+System Fuselage, will the tail wings I have be compatible? Yes, all current tail wings will fit the A+System fuselage directly without the need for the TTF and they are compatible with the new Polycarbonate Pro Shims. The new A+System tail wings are more streamlined at the connection area, for improved performance.

8: What about the Shims? We have simplified the tail connection area so that for most riders the tail can be directly attached to the fuselage with no shim. For more advanced riders wanting faster, looser setups we have new low profile Polycarbonate Pro Shims, which allow more than 5 angle settings at 0.5 degree increments.

9: Will the warranty be valid if I drill into my existing parts for the A+System upgrades? Yes, providing you purchase the drilling kit and use the jig and parts supplied. If for some very unlikely reason a part needs to be warrantied, we will expect to see proof of purchase of the A+System drilling kit.
