Mast base is different on yours - current one uses the oval T-nut system
You will enjoy both your front wings
Thanks! Waiting for my CF1200

and been good so far the CF1600 V1 (with a very daggy CF300 tail hhh .. likes to hum a little at speed) .. better pitch stability than my previous 1650 and also faster by 3knts so far .. still learning the foil (and board and wing ... I am new to all these after 20 yrs windsurfing hhh)
