i have a 5.8 northsail around 2000 model and i have trouble getting planing in moderate wind,would a newer the same size make much differance
Doubt it, as newer sails are less powerful but have wider range.
If you are talking wavesails maybe a 6.0 - 6.2 in modern sails would be similar, if you are talking race stuff about a 7m would be similar now
