Semi-Complete Foils

A semi-complete Foil (partial foil set) is a preconfigured modular system for a hydrofoil in watersports. It usually consists of the front wing, rear wing (stabilizer), and matching fuselage, while the vertical mast must be purchased separately. This option bridges the gap between a rigid complete set and the tedious purchase of all individual parts.

Design and operation

• The hydrodynamic trio: The set provides the complete underwater unit (wings and fuselage), which is perfectly matched. The manufacturer ensures that the ratio of lift (front wing) and balance (rear wing), as well as the length of the fuselage, are harmonious.
• The missing building block: Since the mast is missing, the system remains flexible. The rider decides whether to combine the underwater set with a short aluminum mast for getting started or a long carbon mast for maximum performance.

Features and characteristics

• Perfectly matched hydrodynamics: Since the front wing, rear wing, and fuselage come from the same model range, the angles of attack and balance are optimized from the factory. Incorrect purchases due to incompatible wing shapes are completely avoided.
• High mast flexibility: Many riders already own a mast from a specific brand or want to change the mast length depending on the area (flat water vs. waves). A semi-complete foil allows exactly this modular change without spending unnecessary money on a second mast.
• Economical upgrade path: If you want to enlarge, reduce, or upgrade your existing foil system to a more modern wing type, the partial set is significantly cheaper than buying a complete set including a mast.
