For this Open 40, Hayai, we carried out a large amount of work, in a consultancy role.

We analyzed the performance with our in-house VPP, including the helm balance and effects of the canting keel. This resulted in the conclusion that the foil section of the daggerboard was not optimal. We designed a custom foil section, specifically for the application on this yacht. We also performed finite element calculations to evaluate the strength and stiffness of the board.

Other work was associated with the analysis of the lay-out of the watertight compartments, engines and propeller shaft and water ballast tanks.
