HUNDESTER MANUFACTURER FIRST 5 BLADE PROPELLER

November 2026

Hundested, Denmark – Hundested Propeller manufactures its first 5 blade propeller, continuing its mission to push the boundaries of propeller and propulsion design with the superyacht and commercial marine sectors.
The Hundested 5 blade propeller meets the same standards and can be built to class like the proven Hundested 4 blade and 3 blade designs. The fifth blade makes it possible to further reduce the load on the leading and trailing edge of each blade, to help achieve lower noise levels and improved performance without making the blades excessively large.

Talking about the new 5 blade propeller, Casper Holmegaard, sales engineer for Hundested, said, “High efficiency, low noise, class capability, and efficient regeneration performance are all well-known requirements of propeller design. The real challenge is to combine them in the same propeller. Hundested doesn’t optimise just one parameter; we work to balance several demanding requirements in a single design that is relevant for the vessel type and its operation.”

The first 5 blade controllable pitch propeller complete with a stainless-steel hub was developed to provide low underwater noise, high ice-impact strength, and efficient regeneration while sailing under wind power. The propellers were built to Ice Class and Silent-R.

Casper explains the complexity of the task: “These requirements were prioritised while maintaining high propulsion efficiency. Designing a propeller like this is all about balance. The blades must be strong enough for ice impact, yet slender enough to deliver quiet and efficient operation. Finding solutions to challenges like these is part of Hundested Propeller’s DNA.”

Hundested use Computational Fluid Design (CFD) to make sure that the initial propulsion brief is met, whether that be good propulsion efficiency only or a balance with regeneration performance, more relevant for sailing vessels. Any changes requested by the class must be carefully evaluated to ensure they do not replace efficiency. This process allows Hundested to meet class requirements while maintaining high performance in both propulsion and regeneration mode.
