Windex Wind Direction Indicator 10C for 10–20 ft Boats — Sapphire Jewel Bearing & Reflective Tape

Windex 10C is a compact, highly responsive wind direction indicator designed to show accurate apparent wind on small sailboats and dinghies.

Whether you race a 10–20 foot daysailer or cruise a small keelboat, the Windex 10C gives immediate visual feedback on wind angle so you can trim sails, steer, or tack with confidence. The kit arrives complete with the vane unit, supporting rod, index arms, and mast socket ready for fast installation. Built with a sapphire jewel suspension and reflective tape, this model is engineered to be sensitive in light air and visible at night or in off-angle sunlight without adding drag to your rig.

How does the Windex 10C show wind direction while sailing?

The vane pivots freely on a low-friction sapphire jewel bearing to align with apparent wind. Index arms extend the sightline so you can read the wind angle from the cockpit, and reflective tape improves visibility in low light. The whole assembly mounts above the spreaders or on a masthead to clear rigging turbulence for a truer read.

• Sapphire jewel suspension for ultra-low friction rotation
• Index arms give clear reference marks for wind angle
• Reflector tape on vane and tabs for night and low-light visibility
• Mounts high to minimize distorted flow from rigging

How easy is the Windex 10C to install and maintain?

Installation is straightforward: fit the mast socket, slide in the supporting rod, and attach the vane and index arms. The kit includes all necessary parts for standard 10–20 foot boats; no special tools are normally required. Maintenance is minimal — occasional rinsing and a quick check of the bearing keep it turning freely.

• Complete kit: vane, rod, index arms, and mast socket included
• Tool-light installation designed for common mast diameters
• Low-maintenance design — rinse and inspect bearing periodically
• Replacement parts available if components wear

Why choose Windex 10C over other small-boat wind indicators?

The 10C balances sensitivity, visibility, and cost for small boats where space and weight matter. Its sapphire jewel bearing provides reliable rotation in both light and heavy air, so you get useful feedback across conditions. Reflective accents and a compact profile make it a practical choice for both weekend sailors and club racers.

• High sensitivity thanks to jewel-bearing suspension
• Designed specifically for 10–20 ft boats with minimal windage
• Enhanced visibility day or night via reflector tape
• Competitive price point offering strong value

How will the Windex 10C affect my sailing performance?

By providing a continuous, line-of-sight indication of apparent wind, the 10C helps you trim sails and choose headings faster. Quick, accurate wind angle feedback reduces guesswork during tacks and sail adjustments, improving speed and handling in variable conditions. It’s a simple tool that enhances decision-making without electronic complexity.

• Faster, more confident sail trim and course decisions
• Clear visual cues during maneuvers like tacks and gybes
• Improved responsiveness in light and shifty winds
• No power required — passive, reliable feedback

Who is this for? The Windex 10C suits sailors of small keelboats, daysailers, dinghies, and training boats who want an accurate, low-maintenance wind indicator at a great value. It’s especially useful for solo sailors, instructors, and club racers who need quick visual wind information without adding weight or complexity to the rig. If you want a durable, easy-to-install vane that performs across a range of conditions, the 10C is a practical addition to your boat's deck gear.
