Whale Tail XL

Aluminum Stabilizer and Ski Boat Fin

  • Unique hydrodynamic design
  • Stabilizes bow-light boats
  • Pops skiers up in less time


Flattens wake for water skiing; creates positive, skid-free turns:
  • With bow lowered, visibility and safety is improved
  • Smooths out ride in rough water
  • Reduces porpoising & cavitating
  • Increases top speed and fuel savings in most applications
  • Mounts on the anti-cavitation plate of all inboard/outboards and outboards
  • Installs in 15 minutes with stainless steel hardware included
  • Marine grade aluminum with durable anodized finish
  • Use the Whale Tail XL year-round in freshwater or saltwater to improve performance of any boat!
