Dedicated Propellers With
Value Added Engineering
The Rolla name has been synonymous with the highest efficiency, highest quality propellers in the world since 1963. Offering fully submerged propellers, surface-piercing propellers, and a wide variety of technical support, such as computational fluid dynamic (CFD) hull analysis and seakeeping, today Rolla is an unparalleled leader in propeller performance.
Dedicated Propellers With
Value Added Engineering
Rolla Submerged Propellers start with software analysis of all possible shapes and inputs, including diameter, number of blades, skew, rake and more. The best possible design is determined for the application, then use CFD to fine-tune the propeller load and detect any potential cavitation or flow problems.

A Strong History of
Quality and Efficiency
Founded in 1983 by Philip Rolla, ROLLA SP Propellers SA emerged after two decades of dominating racing competitions with custom-made propellers. Recognizing the potential to enhance propulsion efficiency for high-performance craft on a larger scale, Rolla transitioned to serve a broader market. Today, Rolla offers a wide variety of services for every aspect of propeller design, manufacture and application, from complete hydrodynamic analysis and engineering capabilities to computational fluid dynamic (CFD) hull analysis to sea trials. Rolla has been part of the Twin Disc family of products since 2004, enabling Twin Disc to offer boat designers and builders, engine manufacturers and boat owners and operators one source to satisfy all their propulsion needs.
