WINDEX Dinghy

Product catalog summary

Overview: The document provides detailed information about the WINDEX wind direction indicators, which are precision instruments designed for sailboats to provide accurate information on the apparent wind direction. The document outlines various models, their specifications, and technical features.

Models and Specifications:

WINDEX XL: Designed for larger yachts, with a vane length of 578 mm (23 inches) and a weight of 290 g (10 oz).
WINDEX 15: Suitable for ocean racing and cruising, with a vane length of 380 mm (15 inches) and a weight of 295 g (3.3 oz).
WINDEX 10: Ideal for small cruising and one-design models, with a vane length of 250 mm (10 inches) and a weight of 240 g (1.5 oz).
WINDEX Dinghy: A dinghy model with snap fitting, same dimensions as WINDEX 10.
WINDEX LED Light: Illuminates reflecting surfaces of W15, W10, and WXL, weighing 215 g (0.5 oz).

Technical Features:

The WINDEX consists of a moving vane and two fixed reference tabs, designed to provide accurate wind direction information.
The vane has low inertia, a large fin area, and low-friction suspension sapphire, allowing it to respond quickly and accurately at wind speeds as low as 0.1 meters/second (2/10 knots).
Reference tabs are set to correspond to the apparent wind direction for starboard and port tacking, allowing for precise reading of the relative wind direction with an accuracy of ±1°.
The suspension system includes a sapphire bearing rotating on a stainless steel pin point, with light-reflecting materials for visibility during night sailing.
WINDEX is tested in wind tunnels at speeds up to 80 knots, demonstrating its mechanical ruggedness.

Additional Features:

The WINDEX LED Light enhances visibility in darkness, making it easy to read the wind from anywhere on deck.
The LED Light is mounted directly on the main shaft, is completely sealed, and waterproof.

Conclusion: The WINDEX wind direction indicators are essential tools for helmsmen, providing an edge in performance and accuracy in reading wind directions, crucial for sailing success.

WINDEX UNIQUE VISUAL DISPLAY OF THE APPARENT WIND ANGLE This principle is based on the special sensitivity of the human eye to the asymmetry of an optical picture This principle is based on the special sensitivity of the human eye to the asymmetry of an optical picture. Within the range 0° to 15° the WINDEX type of display indicates a change in the apparent wind angle as small as 1°.
