Variprop 4-Blade Propeller

For open sea vessels with engines above 100 hp.

Especially in blue water conditions, excessive blade loading causes cavitational noises, bubbles on blades and resulting loss of power, just when you need it most in the trough.

The solution is the Variprop 4-Blade: to-date worlds most modern 4-blade feathering propeller, with 30% larger blade areas, less blade loading, much greater thrust and undiminished power.

A smaller diameter fits where others cannot. It has the shortest hub length of any propeller and therefore is able to fit the smallest apertures and still give 100%. Excellent motor sailing power, incredible control and thrust in reverse, no vibration. Independent external pitch adjustments in both forward and reverse allow elimination/reduction of prop walk. It will not spin under sail having near zero drag giving improved sailing speed and steering.
