In-Depth Model Reviews

Windex 6 Dinghy
Purpose-built for smaller sailing craft where every gram counts.
The Windex 6 Dinghy is the lightest model in the range, designed specifically for dinghies, small multihulls, and other fast small boats. Its compact 150 mm vane responds instantly to shifts, giving you real-time wind data without adding unnecessary weight aloft.
- Weighs just 17 g — virtually no impact on your rig
- Flexible mounting bracket fits tube diameters from 45 to 70 mm
- 150 mm vane length balances sensitivity and visibility
- Ideal for Laser, 420, 470, Hobie Cat, and similar classes

Windex 10 C
A compact take on the classic Windex design for smaller keelboats.
The Windex 10 C brings the proven Windex arrow concept down to a size that suits boats in the 10–20 ft range. At 31 g and 250 mm vane length, it delivers clear apparent wind indication without overwhelming a smaller masthead.
- 250 mm vane — large enough to read from the cockpit
- Compact 270 mm total height fits neatly at the masthead
- 31 g keeps weight aloft minimal on lighter rigs
- Perfect for J/22, Soling, Folkboat, and similar small cruiser-racers

Windex 15 Mk2 with BirdSpike
The industry standard wind indicator, now with BirdSpike included.
The Windex 15 has been the world’s most popular masthead wind indicator for decades. The Mk2 version includes an integrated BirdSpike to keep birds off your masthead, protecting both the indicator and your deck from mess.
- 380 mm vane visible from deck on boats up to 40 ft
- BirdSpike prevents bird damage and fouling
- 102 g — robust construction for offshore conditions
- Trusted by cruisers, club racers, and blue-water sailors worldwide

Windex XL
Maximum visibility for larger yachts where the masthead is far from the cockpit.
On boats over 40 ft, reading a standard wind indicator can be difficult from deck level. The Windex XL solves this with a 570 mm vane and 570 mm overall height, making apparent wind direction clearly visible even at significant masthead heights.
- 570 mm vane length — the largest in the Windex range
- Designed for masthead heights common on 40–100 ft yachts
- 150 g construction withstands heavier offshore conditions
- Clear wind reference for helmsman and trimmers from the cockpit
