Windvane Fins
 
UPDATE: Our range of windvane fin variants has been updated recently. The standard F20 windvane fin will continue to be available, however...
- The /LV "Large Vane" fin variants will become a special order item. - A new F20/FC fin variant is now available, which is a larger, stronger fin design which has better sensitivity and performance.
- The F203 fin variant is replaced by the improved F203B which incorporates a side-clamp screw (instead of top-clamp screw)
- The F202 "marine/tight-skirt" fin variant will continue to be available, but with a slightly changed design
- The F204 "marine/tight-skirt" fin variant is replaced by the improved F204B which has a slightly changed design and incorporates a side-clamp screw (instead of top-clamp screw)
- A new F20/SE fin version is now available as part of the "/SE" (Severe Environment) windvane variant/option for better performance in extreme conditions.
The F20 Series Windvane Fins are used for all of our W200 Series Windvanes. The F20 fin is standard, however there are a number of variants available (see above/below)...
