Mast replacement could be feasible if you find another Cruiser 42 with in-mast furling wanting to change for traditional slab-reefing for added performance / trimmability.
I have been playing with this idea (in-mast to slab-reefing) for above reasons, but so far ease of use with family crew have kept me from really searching if there is anyone out there willing for direct swap.
