The patented Whisper Fin blade design: Now available by special order on our Generation-7 Slalom Ski
By special arrangement with Jay Poscente, world renowned for slalom fin tuning, we are now licensed to offer the WhisperFin blade configuration that fits right into our Generation-7 fin block.
“After years of analyzing a vast array of ski setups for skiers of all levels all over the world, a consistent pattern of issues became apparent. No matter what was done with the binding locations, wing and fin, there was nothing that would overcome these issues.
Eventually, it became apparent that the standard “D-Blade” fin was the problem. Though it is generally acknowledged that it is just too big for quick turn initiation, the real problem is how abruptly it hooks up through the finish of turns. And these problems affect skiers at all levels of the sport.
Effective fin area increases as the ski rolls flatter out of turns, causing a spike in tail traction and a skill-testing challenge for the skier.
As the ski rolls flatter exiting turns, the fin grabs and the ski stops turning. If this happens too early, the ski jets ahead, leaving the skier on their back leg with no angle or power. If the fin hooks up too late into too much angle, the tip pops up into a big space-wasting wheelie, or the enormous load pops the handle. Historically, the only defense against these unwanted ski behaviors was a combination of perfect timing and a precarious body position as far forward over the front foot as possible without quite going out the front—skill-testing challenges.
Softening this sudden tail hookup is easily accomplished by reducing the fin’s size, but that comes with a downside. Small fins make no power behind the boat. Nearly a year of experimentation went into identifying the most effective shape for small-fin power. And while an optimized shape made a big difference, even the best small shape fell short of the standard fin’s power behind the boat.
Enter the astonishing maneuverability of humpback whales. It turns out that the bumps along the leading edge of the humpback whale’s pectoral fins help maintain laminar flow at very high angles of attack—a problem water ski fins face all the time. Mix in a little aerodynamic vane theory from an auto racing background and so were born the turbulation slots in the WhisperFin.
The result is an incredibly forgiving, easy-turning fin with quicker acceleration than any other fin in the sport—traits that will help skiers of all abilities. And as an added bonus for short-line skiers, this fin’s progressive hook-up out of turns makes it easier to keep the tip down and engaged straight into early, powerful acceleration.
Then came prototype testing with 47 skiers of all skill levels on a wide variety of skis. It was no surprise that good skiers experienced improved performance on every ski tested—including a new national record and international wins on multiple ski brands. The real surprise was how much beginners improved. Beginners don’t achieve maximum lean angles around turns, so their fins remain heavily engaged at all times. Having smaller fins made turning way easier for this group. Tighter turns coupled with easier acceleration helped the majority of our novice testers set personal bests within two sets.”
