Composite materials may be considered an environmentally friendly option for propeller blades in some applications. While the composite blades are more resistant to corrosion and impact damage than many metal-alloy propeller blades, the water saturation and the propeller application decrease the longevity of composite propellers.

Folding propellers reduce drag while not in use, thereby allowing for more speed or reduced fuel consumption. Folding propellers are no more efficient than fixed blade propellers, and have much poorer performance in astern. Less noise and vibration than fixed blades when not in use, since fluid flow will not cause the propeller to rotate.
Arguably the ideal metal for boat hulls, cupronickel is reasonably tough, highly resistant to corrosion in seawater, and is (because of its copper content) a very effective antifouling metal. Cupronickel may be found on the hulls of premium tugboats, fishing boats and other working boats; and may even be used for propellers and propeller shafts.
A sailboat or motorsailer when voyaging on sail alone will benefit from reduced drag, and just like an aeronautical propeller, a marine VPP may be "feathered" to give the least water resistance when sailing without using power. A VPP is particularly useful when motorsailing (i.e. voyaging under both power and sail), as the VPP can be coarsened ...
The difference between a saildrive and a Z-drive is that a saildrive's propeller shaft is fixed in place, pointing aft, whereas a Z-drive's propeller shaft can be rotated to any azimuth. Traditional sailboat transmissions consist of a simple horizontal output shaft extended rearward from the engine, through the stern via a stuffing box. The ...
