Martec solves the problem of feathering propellers for racing and cruising with its Autostream® line of two and three blade feathering propellers. The Autostream® is the logical and performance alternative for both moderate and heavier displacement sailboats; particularly for hulls with either a modified fin or full keel. And when compared to a fixed prop, the Autostream® significantly reduces drag while improving reverse performance. The three-blade model is also available for %u201CSaildrive%u201D engine installations and may be fitted to Volvo, Yanmar or Bukh saildrives. The Saildrive models%u2019 unique fail-proof cushion hubs absorb shock. And unlike other types of propellers, they cannot fail and leave you without drive.
