My aircraft are also in hangers like that Eric.
As for sails, since they put th plastic snap over covers on the ships I have had no further breakage of masts save for cack handed punters dropping them or trying to pick them up by the sails.
For how to mend a mast see the Home page:-

I did one of these too, but Nightmoss's pictures are far better than mine for showing the details.
