Power Box Fin M88 Superfast 44cm Select SML07510044

Power Box Fin M88 Superfast 44cm Select SML07510044

Description:

The Select M88 Superfast is a high-performance power box fin engineered for maximum speed and control on slalom and speed windsurf boards. Its core is built from high-modulus carbon fiber to create an ultra-thin 8.8% profile (example: 8.8 mm thickness for a 10 cm chord), minimizing drag in all points of sail for exceptional top-end velocity. Select’s Active Flex concept pairs a stiff trailing edge with a dynamically flexing leading edge, producing a very vertical lift that dramatically reduces hull wetted surface and improves stability at speed. This precise balance of flex and twist enhances comfort and control by smoothing lateral loads and maintaining predictable handling through chop and gusts. The M88 is optimized for boards between 85 and 145 liters and unlocks its full potential with experienced sailors looking for aggressive acceleration and sustained high-speed performance. Built for durability under demanding conditions, the carbon construction resists fatigue while keeping weight low for responsive feel. Compatible with standard Power Box mounting systems, it integrates easily into most slalom/speed setups.

Key Features:

• High-modulus carbon fiber construction for strength, low weight, and stiffness
• Ultra-thin 8.8% profile to minimize drag and maximize top speed
• Active Flex design: rigid trailing edge with a flexing leading edge for vertical lift and reduced wetted area
• Optimized twist distribution for stable, predictable handling at high speeds
• Engineered specifically for slalom and speed boards (85–145 L range)
• Power Box compatible for easy installation in standard fin boxes
• Durable composite layup to withstand repetitive high-load use
• Ideal for advanced riders seeking performance gains in competitive or recreational speed sailing
