Wouter,

Exactly. Note that the radius of gyration can be reduced simply adding weight to the mast foot, but this doesn't improve performance. Add more weight and the radius gets smaller and the boat slower.

Something like this could happen if the new rules maintained the minimum mast weight unchanged but eliminated the mast tip minimum weight.

I wouldn't expect them to do that (I hope so) because it would be weird to use new carbon masts with lead weights in the mast foot... The gyration radius would be small, but reducing the minimum mast weight and tip weight obviously make a lot more sense.

Regards,
