The picture looks like both mast and boom are bent, how much to replace
both of them?. If he ordered sails instead this tell me to replace the
boom and

I don't see any indication that the mast is damaged. Replacing the boom would
be easy and not that expensive. He might even do it for free as the rig size is
pretty common. Of course, finding the exact boom might not happen, which shows
how foolish he was to order new sails first.
Ass-backwards lubberly thinking by Capt. Neal...as always. You note he's not
defending this point. How could he? The boom is BENT!
