ProWatercraft introduces the new Hybrid Flex Composite (HFC) that is designed to flex supporting your riding style. HFC blows all the other rigid products out of the water with many improved features. These sponsons not only hold up better than the industry standard aluminum and fiberglass sponsons, but limits bouncing, reduces subbing, even MORE stability, and better grip. Check out our video below for more additional info!

Our “Performance Rear Sponson” kit is designed to improve the riders confidence when riding their Stand up watercraft. The design was created by Chris Hagest. He says: These Performance Rear Sponsons offer improved turning grip, better stability in a straight line and when leaning over in a turn. The difference between us and the other options on the market is grip and high speed turning the ski is easier to lean which makes the ride smoother through the complete turn. The aluminum sponson bolts to the inside of the bond flange and it comes with two hardware options. PW-SP-200 is for flat head bolt to make a seamless fit under the aftermarket bumpers. The PW-SP-205 comes with button head bolts to work with the stock bumpers. Race proven, designed by the pros, built for the best in the world.

  • How can this new material improve my racing?
    We’ve covered the issues many riders face every time they race. HFC gives the sponson enough flex to allow itself to adjust to your weight, speed, and the water condition you race in. Advantages of these sponsons include pressure reliefs and reduced lift from the rear while turning.
  • What makes HFC any stronger than my aluminum or figerglass ride plate?
    Aluminum sponsons crack and chip, same with steel! Our new material eliminates those issues. HFC is the only material we found that is chip, crack and rust resistant. Not to mention the pressure relief design to almost eliminate rear lift.
