Vane Plastimo Tempest 12 — Precision Masthead Wind Direction Indicator

Guide every trim and tack with confidence using the Plastimo Tempest 12 wind vane, a compact, ultra-responsive masthead indicator engineered for sailors who demand clarity at a glance. Its low‑inertia, perfectly balanced arrow pivots smoothly to reveal wind direction in the lightest breeze, while the high‑visibility design makes reading immediate from cockpit to bow. Built for the marine environment with UV‑stabilised, corrosion‑resistant materials, the Tempest 12 pairs lasting durability with refined aerodynamics to deliver accurate, stable and silent indication on cruising routes, training days and race starts alike.

Key Benefits and Applications

• Instant wind awareness — Read wind shifts in real time to optimise sail trim, execute cleaner tacks and gybes, and keep your boat consistently in the groove.
• Responsive in light airs — The balanced, low‑friction pivot reacts to subtle puffs and headers, helping you keep way on when the breeze softens.
• High‑visibility from the cockpit — A contrasting arrow and tail enhance readability at distance, supporting quick decisions when helming or calling laylines.
• Robust marine build — UV‑resistant polymers and corrosion‑proof components stand up to sun, salt and spray for reliable performance season after season.
• Compact with low windage — Streamlined geometry reduces drag at the masthead while remaining large enough for crisp, stable indication underway.
• Versatile across sailing styles — Equally at home on dinghies, sportboats and cruising yachts, from training sessions to club racing and coastal passages.
• Confidence for crew development — Clear directional feedback supports coaching and skill building, accelerating progression for new and experienced sailors.
