The 2025 V1.4 version of the Submarine represents the ultimate in harness drag reduction. Years of feedback from the world's top pilots helped us to improve many essential details. A unique magnetic pod closure system is air-tight and hands-free. The new inner structure of the tail prevents the tail from obstructing the pilots view in stall. It also features a new upper body closure system, larger pockets, and easier access to instruments. Overall, the V1.4 is significantly more comfortable and more efficient. Thermal comfort inside the pod remains excellent.

Nomenclature: V1.4 means this is the Version 1 of the Submarine structure, and the 4th generation envelope.

The Submarine’s performance and comfort have now been thoroughly proven in the highly competitive PWC circuit and during world record distance flights. We thank the pilots who assisted us during the multi-year development process. The Submarine has won virtually every major event since its release.

Solid yaw stability is noticeable at high speeds thanks to the optimised shape of the profile. The overall comfort of the Submarine's structure helps to save energy needed for long and demanding flights. The new magnetic hands-free pod closure provides increased safety on take-off, landing, and allows trouble-free low saves. The risk of pilot vision being obstructed by the tail during stalls and back flights is now reduced. Pockets and instrument panel were made larger and easier to access. All improvements have made it a more user-friendly competition harness.
