The Foil Drive Trench is the next evolution of powered foiling performance — developed through direct collaboration between Sunova Surfboards and the innovators at Foil Drive.
Based on Sunova’s proven Foil Drive model and redesigned with an integrated trench system, this board is purpose-built to pair seamlessly with Foil Drive Gen 2 and Gen 2.5 (Fusion) systems, delivering effortless lift, early planing, and serious performance once on foil.
Friendly to ride, but an absolute weapon when pushed.
Designed Specifically for Foil Drive
With increased bottom surface area, rolled rails, and minimal rocker, the Foil Drive Trench begins to plane almost instantly when power is applied. The result is easier take-offs, smoother acceleration, and more time flying above the water.
Whether you’re prone foiling, exploring downwind runs, or extending sessions with assist power, this board makes getting on foil easier than ever.
Who This Board Is For
- Foil Drive Gen 2 & Gen 2.5 riders
- Prone and assisted downwind foilers
- Riders wanting easier lift and longer sessions
- Skill levels from novice through to advanced
Simply choose your size based on rider weight and experience.
