Do you plan to keep sailing the 125 liter Goya?
If so, the Carve 131 would overlap quite a bit.
If not then the Carve 131 sounds better.
I have not sailed the larger new Carves, but did sail the 2011
Carve 111 this weekend and it sails farily big, so the C-131 could be good
if you don't keep the Goya.
If you keep the Goya, the Carve 141 will get you going very early, but a little larger
sails (8.5 m2?) would seem appropriate for light winds on the 141.
Hope this helps,
