In Case 48, Walt and I catch up with Chris Radkowski, the designer behind F4 Foils. While Walt was in Maui, he picked up a setup from Guido and could not stop raving about the new Orca line for downwind—so of course, I had to try it too. Spoiler: they did not disappoint.

What makes F4 stand out is that they’re not afraid to throw carbon at an idea. Constantly reviewing designs, experimenting with different stiffness layups, and fine-tuning wing concepts, they landed on something special with the Orca—exactly what we’ve been looking for in a downwind foil.

And they’re not stopping there. Expect Orca surf foils soon, along with expanded 11mm mast sizes. The foil world is looking brighter with F4, and we’re genuinely excited to be working with them.
