Better Materials

Wing uses polyurethane exclusively in the construction of our tubes, sponsons and inflatable boats. The expected service life of a polyurethane tube is 7 - 8 years versus Hypalon which is only five. Polyurethane also has twice the puncture resistance and four times the abrasion resistance than Hypalon or PVC.

Bottom line: your Wing boat is tougher and it will last longer.

  • Wing polyurethane has twice the puncture resistance and four times greater abrasion resistance than Hypalon.
  • Expected service life of a polyurethane tube is 7-8 years versus only five years for a Hypalon tube.

Polyurethane vs Hypalon

Better Technology

Wing uses heat to permanently bond its air-holding seams because glue doesn’t last forever. Wing’s air-holding tube seams are thermo-welded making them into a single, inseparable piece that is stronger than the original fabric.

Glue has something called a “shelf life.” That means after time it loses its effectiveness, becomes brittle and no longer adheres. In the case of air-holding tubes keeping your boat afloat, that’s not good.

  • Our air-holding seams are permanently thermo-welded, not glued.
  • Wing’s proprietary CAD software factors material strength and stretch into the patterning of each boat.
  • Typically fast 60-day turnaround on new or replacement sponsons.


Construction Technology

Better Design

Decades of white water rafting experience taught our founder a thing or two about durable inflatable boat design. For example, excess weight erodes performance. So we taper tubes and sponsons when appropriate which also can result in greater usable interior space.

Bottom configuration also contributes to superior performance relative to speed, handling and fuel consumption. So Wing designs combine the right amount of angle, keel inflation and/or strakes to get the job done and help you get back home.

  • Tube design can reduce weight and increase usable space.
  • Wing designs result in optimum speed, handling and fuel economy.
  • Wing polyurethane products are Buy American Act and Berry Amendment compliant
