Most blocks on ships are not allowed as opposed to last season. However some blocks leaving a questionable reasoning of being left out, such as these: Chest(s) + trapped-chest Dropper Noteblock Block of redstone (can't power lamps, literally the only usage of it.) Cobweb Brewing Stand Cauldron Note: I understand most were removed to stop duplication on ships. (a.e torches and etc.) But those listed above serve no reason to be blacklisted on ship building.
