Folding propellers have come a long way since they were first used as long ago as the 1920's! Darglow manufactured thousands of 2-bladed folding propellers in the 1970's and 80's and these were among the earliest reliable folders available. They allowed very significant improvements in sailing speed but were never as good as fixed propellers for motoring and were not as effective in reverse.

Darglow now offfers the Danish Flex-O- Fold which represents the current state of the art in folding propellers. Due to greatly improved blade design, these modern propellers now offer thrust comparable to fixed propellers in forward and powerful thrust in reverse thanks to improved weight distribution, blade area and shape. Because of their low drag profile under sail, average sailing speeds can increase by as much as 15-20% compared to fixed 3 bladed propellers.

Flex-O-Fold propellers are available in sizes from 12'' to 22'' diameter and can efficiently absorb from 7 to 100hp.

Our new blade design works efficiently without vibration.

The ideal weight distribution of the heavy blades provide exceptional stopping power even at low rev's.

The zinc anode covers the gears providing its normal protective function.

All Flex-O-Fold's are delivered complete, including tools, Loctite and easy to follow installation instructions.

Fits directly on existing shaft, without modifications.
