don't you think that the Tornado class rule (minimum SMG set at 3,45 m i.d. 81,2% of maximum foot set at 4,25 m) makes the Tornado's spi different from the others? i.d. more "fat"?
All the other catamaran class rules states a SMG which is 75% of foot. This could explain the reason why Gransegel spis are excellent for Tornados but fairly poor for other catamarans (for istance F18s)
Thanks in advance for yr opinion
