The Autostream self-feathering propeller has evolved through 8 models, over more than thirty years. Many experienced sailors tell us they consider the Autostream propeller to be the best propeller of its type available – a fact we are proud of. They offer excellent propulsion, control and low-drag. We know by the fact we sell very few parts, that the reliability and robustness is second to none. Self-feathering propellers are the propeller of choice for most cruising sailors. It is also ideal for those with difficult docking conditions, hard to handle sailboats or those that just like the reassurance of extra control – all with little drag whilst sailing.
