In comparative trials held on the River Hamble, in the UK, the Brunton-Weil self-pitching propeller, known as the Autoprop, came out with top ratings. Using a Moody 'Eclipse 33' motor sailer, the Autoprop's speed, acceleration and crash stop times were compared with those of four other closely-matched propeller types. The manufacturer claims that in certain cases, crash stop times were reduced by more than 50% and acceleration to 6 knots was improved by up to 70%. The Autoprop has independent, freely pivoting blades that automatically adopt the most efficient pitch.
