Rolla is worldwide leader in design and manufacture Custom Propellers for Pleasure, Military and Commercial vessels.
For each specific application the propeller has a dedicated design and a dedicated pattern. All the design codes are proprietary and have been devolped in house.
The propellers can be designed to meet any Classification Register rules as Lloyd’s, ABS, RINA, etc.
Since 1963 the name Rolla has been synonymous with the highest efficiency, highest quality propellers in the world.
Today this means dedicated propellers up to 2.5 meters in diameter. It also means complete hydrodynamic engineering service, unique in the industry.
Starting with CFD analysis of the hull, including sea keeping, to the most sophisticated CFD propellers.
This integration of hull analysis and propeller design allows the most efficient solution to any performance and use profile given. This is where no one else is today.
After 2 years testing Propspeed on propellers Rolla confirmed that Propspeed works perfectly.
Today Rolla SP Propellers SA is applying Propspeed on their every single new propeller.
Propspeed prevents marine growth from bonding to metal surfaces below the waterline. Propspeed works becouse it’s slick, not becouse it’s toxic.
Propspeed is a NON TOXIC coating to prevent fouling of propellers, shafts and struts.
