Most folding and feathering propellers are designed to reduce drag when sailing, their performance under power is a compromise. The Autoprop is designed without such compromise, offering greatly enhanced overall performance.

• Under Power you can achieve your usual cruising speed at comparatively lower engine revolutions, hence potentially increasing the cruising range.
• When motor sailing, the Autoprop will continually adjust to take into account the driving force from the sails, such that the engine may be run more slowly and quietly.
• The Autoprop exhibits the same characteristics in astern as in ahead ( where the gearbox ratio in astern is the same as or similar to that in ahead) which means that maneuvering, directional stability, power and speed can all be considerably improved.
• Under sail the Autoprop's three blades align themselves with the water flow, reducing drag by up to 85% compared to a fixed three blade propeller.
• Autoprop will fit straight on to the existing shaft and should require no further adjustments after installation. Each Autoporp is designed to be matched to your yacht and is carefully tested at the Bruntons's own test tank to ensure it's conformance to the designed criteria.
• Autoprop is available in in 2 and 3-blade configurations to suit both Shaft Drive and Sail Drive Installations.
• Autoprop will reduce your main engine fuel consumption by upto 30% compared to any equivalent size fixed or feathering propeller. So your Autoprop will assist in reducing your carbon emissions and help contribute towards a better envioronment for us and for the future generations. 
• This is often referred to as the Green Propeller
