Single handers for 65kg

Im around 65kg and i used to have a Vortex Asymmetric and
it was a great boat. Because it is so stable, even in heavy
winds it is still very manageable.

Currently i sail an RS600 and, while being at the other end
of the stable scale, is a very nice boat to sail. The
downside is that with the big fully battened main, keeping
control in bigger winds is a lot tougher. It is still good
fun though.

Of course it all depends on your skill level, what you want
from the boat, whether you want hiking or trapeze etc...

Usual advice / questions will follow - often most fun to sail same as others at your club, what sort of sailing do you want etc etc All perfectly valid. But I have   two vastly different suggestions -

For competitive class racing and a big choice of opens, with World / Europen and even Masters events - Laser Radial - as long as you don't mind hiking..

For trapezing, blasting and a scattering of good opens around the country - Vortex - especially if your club is big enough to allow the Asymmetric option..
