The new Wärtsilä propeller design is considered an energy-saving technology reducing also emissions and improving CII rating. A new propeller design, along with reduced vessel speeds and engine power, can lead to propulsive efficiency improvements of up to 15%. Redesigning the propeller can lead to significant efficiency gains for vessels.

At the 2020 Miami International Boat Show, Philadelphia-based Sharrow Marine introduced the culmination of a seven-year research and development project called the MX-1 Sharrow Propeller. Unlike every prop that's come before it, rather than blades, the MX-1 has loops of metal attached to the hub. How does this change the dynamic?

New Revolutionary Sharrow Prop Tested Full Report w/Video BoatTEST
A boat propeller is usually designed with two to five blades (though sometimes more). In the first instance, the number of blades is decided by the weight of the vessel: the greater the weight, the greater the blade area required to push it through the water with a minimum of slip and cavitation.
5 Best Boat Propellers 2023 [Increase Performance & Fuel Economy]
A radical new toroidal boat propeller is being touted as the single biggest advance in propeller design since the 1930s. Claimed to deliver significant fuel savings across all different types and sizes of craft as well as faster planing, higher top speeds, superior handling and reduced vibration, it sounds almost too good to be true.

1. Optimize the Number of Blades A lesser amount of blades tends to equal a higher theoretical efficiency while a larger number increases the propulsion. As blades are added to the design, they increase the amount of drag but improve the ability to move water, resulting in a smoother (and less vibrational) motion.
Boat Propellers for Powerboats and Sailboats Volvo Penta
The idea behind propelling any vessel at sea is chiefly because of two reasons: 1. Manoeuvrability and variation of speed 2. Overcoming the resistance encountered by the vessel at sea Resistance, as we are aware of is a principal phenomenon inevitable in all bodies floating in real fluids.
New boat propeller promises more speed, efficiency
Basic Boat Propeller Design. Understanding the basics of boat propeller design can help ensure that boaters get the most out of their engines and boats. The shape of a boat propeller is typically composed of two or more blades connected to a hub at its center. The number, size, pitch and cup (or rake) angle all contribute to how efficiently it.
