For Nozzle Applications

Designed for vessels that require reliable thrust and precise control at low speeds.

The VEEM Kaplan propeller is a high-thrust, low-speed propeller engineered for maximum efficiency and manoeuvrability in heavily loaded or restricted-speed applications. Its unique duct-compatible blade geometry delivers exceptional bollard pull, station-keeping performance, and thrust efficiency, making it ideal for workboats, tugs, and dynamic-positioning vessels. Each Kaplan propeller is precision-machined and can be customised for specific duct types and vessel operating profiles.

With full customisation to match duct type, engine power, and operational conditions, the VEEM Kaplan propeller provides dependable performance where it matters most.

Manufacturing - light years ahead

Bespoke Design

Every VEEM propeller is engineered to match the exact needs of each vessel. Our customised designs draw on decades of practical insight, advanced CFD and FEA capability, and a dedicated team of highly skilled marine propulsion specialists with real-world experience.

Absolutely Identical

Our manufacturing technology ensures propellers are cast and machined to micrometre accuracy, enabling identical replacements and perfectly matched left–right sets with no performance drift across vessel series.

Fully CNC Machined

VEEM propellers are 100% 5-axis CNC-machined to hair-thickness accuracy over every surface, from boss to blade tip, unlike semi-CNC alternatives. This guarantees perfect form, stability, and repeatable high-performance hydrodynamics. Learn more about VEEM vs Class 1 & S-Class >

In-House Alloying

VEEM is one of the very few propeller manufacturers that alloys all metals in-house. This ensures total control over material chemistry, consistent quality, and optimal strength to resist cavitation, corrosion, and fatigue.

Decades of Data

Every propeller benefits from VEEM’s decades of sea-trial data, hydrodynamic research, CFD/FEA validation, and continuous refinement—delivering industry-leading efficiency, smoothness, and thrust performance.
