Darglow Flex-O-Fold Propellers
Danish Flex-O-Fold folding propellers
Darglow is a long-standing supplier of the Danish Flex-O- Fold range, 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% compared to fixed 3 bladed propellers.
Available in sizes from 12” to 22” diameter, Flex-O-Fold prop’s can efficiently absorb from 7 to 100hp.
Two and three blade Flex-O-Fold propeller options available to choose from
When it comes to propellers, Darglow can help and advise on the exact requirements to suit you own particular needs.
Flexofold low drag folding propellers are suitable for sailboats and multihull yachts.
The folding propellers are available as 2-Blade, 2-Blade racing and 3-Blade in multiple sizes and pitches. All delivered for both shaft- and sail drive installation.
What propeller to choose?
That depends on what sailing boat you have, the engine and not least – your priorities!
A 2-blade propeller is more efficient than a 3-blade. Surprised? Well, most people are.
The 3-blade, because of its larger blade area, will accelerate the boat faster. This means a 3-blade is better around the docks, when powering against a head sea and when stopping.
Easy to install
All Flex-O-Fold’s are delivered complete, including tools, Loctite and easy to follow installation instructions.Fits directly on existing shaft, without modifications.
Hub and blades are made of Nickel Aluminium bronze. Pivot pins and bolts from Cr-Ni-Mo austeritic stainless steel (ANC4)

This is the best Flex-O-Fold for most sailors, owing to the powerful thrust in forward and reverse.
Flex-O-Fold Cruising 3 Blade
