The Tornado WAS "scaled down" BUT when they say scaled down they don't mean that it was simply scaled down proportionally, but that it was scaled down incorporated the differences necessary to make the balance and bouancy work at the smaller size ie the length reduced by 20% but the bouancy only by about 5%. Similarly with the depth of the hulls and the entry at the bows and "rocker". When journalists, for their convenience say "scaled down" they just see that the two "look" similar with one being slightly smaller. It would be more accurate to say that the Tornadoe was "BASED" on a previous design of a 25' cat.
