I have sailed both the 2013 Carve 111 Wood and the 2013 Futura 121 Wood this summer.
As an Intermediate rider 75 kg, I enjoyed both boards very much. Both are easy to ride & jiibe and fast boards.
I think the carve is slighly easier to jiibe and glides more easily onto plane compared to the Furura.
Often it takes some time to get used to new boards, but these boards were both very easy and fun to ride!
