I enjoyed reading this some reason. Armorers could repair the exterior plates of the ship walls. Weavers can synthesis sturdy ropes also. Leather patchwork might be more suited then cloth repairs for the sails as well as the clothing of the staff. Can't have our employees looking drab in front of VIP guests. A royal airship must be expected to serve hors d'oeuvres at the very least! A need for cleaning utensils (blacksmith) and cleaning solvents (alchemy) to wash and polish the ship to keep looking its very best. Carpenters would have to make sure the mast, helm and deck are all in top condition for flight.

As for the logging behest, do mandragoras have vines? Maybe they were actually ochu type monsters.
