Windex 15 BirdSpike included will be the perfect choice for all cruising and racing boats from 5-12 (15-40 feet) meter that have some problem with birds on their mast.
The WINDEX Wind Indicator offers exceptionally good performance. The secret is the needle that rests in a safari layer, which means that Windex 15 finds the shifts even in extremely weak winds. With the carbon BirdSpike included it will keep the birds away from your Windex without effecting the function.
