Hello Optimist
I can report that the CC19 sails very well into the wind, particularly when carrying full sail.
Here is a GPS plot of Mary Ann short tacking east out of my mooring (Whickhope inlet, Kielder Water).
The wind was light, about F1 Easterly. Full mainsail, Staysail and Genoa. As you can see she was tacking through a true 70 degrees (less than that on deck). It certainly impresses me.
My previous boat was a Winkle Brig which had twin lifting centre(?) plates, which gave great space in the cabin (no centre-board box) but it would take twice as many tacks to cover the same distance as the CC19.
I would suggest that you persuade someone to give you a demo sail, where are you based?
Cheers
Dennis
