Did you know that a significant amount of energy is lost in the hub vortex behind a conventional propeller?

Boss Cap Fins (PBCF) are designed to interact with this vortex, partially straightening the rotational flow and recovering part of that lost energy. The result?

✔ Reduced propeller torque
✔ Improved propulsive efficiency
✔ Up to 1–2% power savings at given operating conditions

While the gains may seem modest, this simple and cost-effective passive device can translate into meaningful fuel savings and emission reductions over time.

At VICUSdt, we design and optimize propulsion solutions using advanced CFD analysis to ensure measurable, real-world performance improvements.
