thank you Ian and Benz for your explanations about performances and differences
I didn't have the opportunity yet to speak with a rigger.
My boat is custom made, so I cannot really speak with other owners already tried a different sail plan.
What interested me (even just to increase my knowledge

) is the "recommended distance" in between the sail on a 10 m, no bowsprit boat .
There is a rule about it or is just dictate by the experience of the rigger ??
What is your opinion??
If more information can help, please ask!!
thank you!!
As I said before I sailed quite a ot of miles with the configuration i have: a big genoa downwind or medium size staysail when the wind reinforce and I have to go upwind.
Now the staysail is ready for the garbage bin and I will maybe do some upwind and stronger wind sailing.
For this I was thinking about put on the furler a smaller working jib/yankee to use with a staysail
looking forward for your comments
thanks
Roberto
