Concept Sailracing Masts
Terms and Conditions
by Suntouched Sailboats
The new Concept Sailracing Finn mast has been developed by Michele Marchesine and his team. They have taken 20 months from the start of the project and have launched the new Concept Sailracing CK01 Finn Mast.
CK01 Finn Masts outstanding performances are due to a skilful mix of engineering developments, on-the-water top sailors' experience and special high-tech manufacturing technologies.
The key challenge for the team was to make these three factors converge and give birth to a new, modern generation of Finn masts.

Concept Aerodynamics Design
Director:
To get the maximum aerodynamic performance from a mast it has to work perfectly together with the sail, this is influenced by a number of variables combining aero shape, dynamic bend and torsion. The mast bending characteristics have to support the sail to provide the best sail shape over the wind range and must also achieve the best possible aerodynamic of the combination mast and sail.
The task we had for the new Concept CK01 mast was to design a wing within the rules which provides those characteristics.
To get a better understanding of the flow around the mast and sail we have run exhaustive CFD flow simulations and tested different profile shapes to evaluate the effect on the lift and drag parameters for different lift conditions. This in all wind speed ranges and under laminar, semi-turbulent and turbulent air flows.
New design wing shape was, through the process, tested under differently bent and twisted FEA models in order to streamline performance and achieve what at CSR we call High Efficiency Flow Dynamics.
In light winds our CK01 mast, combined with modern Finn laminated sails, produces higher lift with a smaller separation bubble on the leeward side and no virtual stall.
In the mid range the achieved lift to drag ratio ensures best performance. In high winds the mast sail combination produces significantly lower drag and allows easier helm and better speed.
We are confident that the High Efficiency Flow Dynamics achieved with our CK01 teardrop shaped profile give the best performance in all wind conditions.

Concept Sailracing masts are built with the most advanced technologies available in composites construction: full autoclave curing cycle and aeronautical quality standards ensure top performances, reliability and consistency of the product. This was possible thanks to the collaboration of Vega, an established Italian company specialising in composite structures who lead the way in the production of high technology parts and special fittings and have wide experience with custom projects.
Armando Casazza, aircraft engineer at Vega:
Besides the complex design phase, we focused on the production stage. Every single mast passes through the hands of specialised workers, therefore accuracy and quality checks are crucially important. Superior quality results are achieved through a skilful mix of automated and manual processes.

In a short period of time, the concept mast has already enjoyed notable success at the highest level. The Delta Lloyd regatta was won by Ed Wright, using a Concept mast in every race, the Italian Open Championship was won by Giorgio Poggi, using his Concept mast. The masts are now well represented on the international circuit and several top sailors have already purchased their second Concept mast.
