VEEM Extreme

The most efficient shaft-line propulsion system ever developed

18.1% reduction in fuel consumption and carbon emissions, certified by Lloyd’s Register.

Shaft-line propulsion has existed since the very beginning, and for decades the propeller concept remained largely unchanged.
Today, VEEM introduces a true breakthrough: EXTREME, a revolutionary propulsion system that delivers measurable gains in efficiency and performance.

A complete, integrated, custom-engineered solution VEEM EXTREME is a fully integrated, custom-engineered package comprising:

  • Propeller
  • Shaft
  • Struts
  • Rudder
Each component is designed to work together as a single optimized system—not as standalone parts.

Innovation that cuts emissions.
Efficiency that changes propulsion.

Verified results: lower fuel burn, lower emissions, higher speed

Testing conducted on VEEM’s trial vessel and verified by Lloyd’s Register recorded:
  • 18.1% reduction in fuel consumption and carbon emissions compared to a traditional system fitted with a Class 1 propeller
  • 8.5% increase in maximum speed
Consequent advantages: range increase, powertrain downsizing, extended range in full electric mode to access to the marine protected areas.

Why it performs: multiple innovations working together

EXTREME’s outstanding results come from the combination of several advanced design features, including:
  • A new V- or P-shaped strut
  • A flow-aligned rudder, designed to minimize hydrodynamic losses
  • A patented shaft/propeller coupling, reducing shaft stress by 20%
  • The new EXTREME propeller, featuring an exceptionally fine NACA blade section made from a proprietary ultra-high-strength stainless-steel alloy
  • The exclusive INTERCEPTOR system, enabling pitch adjustment “in the blink of an eye” for optimal efficiency across varying operating conditions

A new future for shaft-line propulsion

With EXTREME, VEEM has created the most efficient shaft-line propulsion system ever produced, giving this configuration a new and prosperous future while reaffirming VEEM’s position as a global leader in marine propulsion innovation.
