Most likely not. Was it a new mast? Possible warranty claim if under 12 months (depending on how it was cracked). If its over 2 years old, not worth repairing in my opinion.
I do have a cheap 400cm mast for sale if your interested!! 
thanks for the offer Mucksy, but i whent and saw simon at board crazy and bought myself a new one.
can it be repaired?
