Want to learn how to Wing foil, but you don’t know how to foil?  This SUP is your answer.
Slingshot took an already easy to paddle SUP and added a center daggerboard or keel that helps you stay upwind when learning to fly hand held wings.
The SUP also comes with a paddle, so you can use it also as an SUP.

Slingshot Crossbreed 11′ Airtech Package w/Supwinder

I was able to get a customer out on this Crossbreed SUP a few days after they first were delivered.
It was SO easy for them to learn how to fly the new hand held inflatable Slingwing wings in the wind while riding this SUP.
Having that added center keel or daggerboard is just plain genius.  A regular SUP will be nearly impossible to stay upwind.
This SUP with the Supwinder keel makes winging life just that much easier.
AND… get an inflatable SUP and a paddle ad pump included with the package.  Pretty cool new product Slingshot.
Well done.  Bob

Step into the new and exciting sport of Wing surfing and gather the basics of upwind and downwind sailing on a soft, stable platform before taking the next step to a dedicated foil board. We fitted the popular Slingshot Crossbreed 11’ inflatable SUP with a center fin box that houses the sUP WINDer keel. The removable sUP WINDer center keel fin can be installed in seconds and is perfect for teaching new wingers how to stay upwind or for paddlers who desire better straight-line tracking. Remove the center keel fin and you are back to standard paddling with an inflatable SUP that is lightweight, durable, portable, super safe and it feels like a hardboard when fully inflated.

The convenient SUP backpack holds everything you need for an easy escape into the wild.


The Crossbreed 11’ Inflatable has been a family favorite SUP for years, and now water-people of all generations are looking to crossover from paddling to winging. The addition of the sUP WINDer keel fin allows the whole crew to try their hand at the new sport of wing surfing, learning the basics of wing control and staying upwind.


  • With the sUP WINDer removable keel fin box pre-installed it is the perfect learn to wing surf tool.
  • Versatile shape; great for kids, dogs, families, beginners, experts & parties.
  • Portable and easy to store – fits in the included backpack.
  • Hardboard performance in an inflatable package – inflates to a firm 15-18psi.
  • Lightweight, super durable DropStitch construction.
