Hi,

I don't know; I thought the Fox was an iF20... It could be a self-declaration error because the ISAF SCHRS system which was used at the event recently changed iF20 from .94 to .95 (by removing a carbon penalty). See http://www.schrs.com...

There again, the table lists values based on specific measurements and 'formula' values based on what is presumably min/max parameters (as appropriate) of the formula rule. So a boat which is an iF20 may or may not have the same rating as 'the' iF20 value... I think Texel lists actual/formula values as well...

Regards,
Colin
