Thanks for all the replies guys.
I'm thinking that if the hardware is suitable building new hulls to slide under the hardware as long as I dont compromise the new cat too much. Then overtime after I've sorted the junior sailing out I could add the proper bits.
I think the mast would struggle with 2 on the wire but this would be my single hander cat, as the Nacra covers me 2 up.
I'll post some pic's of the hardware, if you could let me know how suitable, but off course I'll start with the pic of the damage. (everyone loves a broken cat pic).
regards
