Collection of ships

4 ships with varying sizes. create blocks are only used for parts of the mast and sails so most of the ships will also work in vanilla with a few changes.
note that when assembled as aeronautics contraptions these ships will be hard to keep upright, especially if copycat weights are their default values. copycats+ aeronautics weight can make this more manageable by giving reasonable weight to copycat blocks, but you'll still want something like create deep seas that provides floater blocks so you can stabilize them manually.
