Wouter,

the changes made the F17 are so it fits the 104 class, And its appears that its been worth it too.

The F17 has just won the French 104 nationals and was also the standout boat in the recent French magazine test.

If someone has the time (and inclination) maybe its worth recalculating the results from Texel using 104 for the vipers handicap (2 up) and then if Geert's boat was heavier than the F16 handicap how about recalculating it with the correct handicap and see how he would have gone?

Oh and if you have technical issues scanning and posting the "light F17" certificate you can just fax it to me and I will do it for you.....
