Performance comes from two main areas: the first one is optimising the relationship between key parameters such as length, displacement, sail area and righting moment; the second is a specific refinement of these parameters within themselves.
The construction in full pre-preg and Sprint carbon fibre. The structures were designed in complete compliance to ISO Standards. The criteria was to minimise weight whilst keeping the construction method and procedure in line with that of a serial production setup. I believe we managed to achieve the objective since the weight of all the structural components, including the keel fin, is just over 2,000 Kg. The keel fin itself only being 160 Kg and built mostly of high modulus carbon fibre. The structural criteria for the carbon fin was specifically focused on eliminating flutter as well as satisfying the GL Standard and recommendations, which impose bending and grounding load cases.
