Totally agree that an all carbon boat would be ideal and no a F16 at 107 kgs is not all carbon, just look at the Vision, almost all glass hulls and just carbon mast.

We have hacked the weight cost / issue to death over the years, but little did we appreciate that 50lbs makes very little differnce in speed and yet softens the harshness of low weight in handicap ratings.

This is something that has escaped most of us used to more V shaped hulls of past generations of boats and something that the controling authorties such as ISAf have yet to catch up on ( although they are aware that boats are no longer fitting into existing computer models and adjusting them slowly ).

It is also something that most internet sailors just cannot comprehend and it would seem that the few who are actually sailing these boats are now beginning to understand.
