Belle-Vie does nicely to weather down to about 25 degrees, then she begins to lose power. I can pinch to about 20 degrees, but after that air flow starts to detach from the sails whereby she slows fast.
We purchased her in 2002 and have sailed her solo thousands of miles all over PNW waters. Fast, stiff and very comfortable. No regrets and would do it all over again, and again...
