"All that aside who would buy a boat without sails or mast?"
I know someone who did. Bought a derelict from a yard and got the rest together and still made out OK on the whole deal--but he's got great luck with such things, and found a mast and boom that were "close enough" to the original to work.
In Florida, I'd call Sailorman and if they can't get a replacement rig--ask them about other breakers' yards and places to try calling. Locally--because shipping can be a huge expense.
