A new propeller design will likely start popping up on boats in Alabama and across the nation in the next few months—provided that the manufacturer eventually gets the price down to affordable.
Learn Ship Design Types of Propellers
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.
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.
