A small cardboard pirate ship is a great way to get started in model ship building. We will be building a small Spanish pirate ship. This ship is very easy to build, if you have the right materials and patience.
Things you’ll need.
paint and paintbrush
yarn or thread
cocktail sticks 
Step 1. Draw the shape of a ship [as if you were looking at it from the side] onto a piece of cardboard. It should be about 10 inches long. Then cut this shape out with scissors.
Step 2. Use your first side,you just cut out as a template and trace it on another piece of cardboard. Cut this shape out also,you should now have 2 pieces the same.
Step 3. Cut off about 1 inch of the pointed end of both pieces of cardboard .
Step 4. Cut a piece of cardboard for the bottom of your ship. It needs to be long enough to reach all the way around the curves at both ends and reach the top of the sides. Cut this piece about 2 inches wide.
Step 5. Glue the full bottom onto one side then the other,using stick glue. Allow this to dry completely.
Step 6. Next you’ll need three cocktail sticks to make the ship’s masts.
Step 7. Carefully snip off the top third of the sticks, so that they’re all about the same length.
Step 8. Push one of the sticks into the bottom of the ship in the center. Don’t punch all the way through, just enough so it will stand up on its own. Use stick glue around your first mast.
Step 9. Do the same thing again, with one stick just behind the raised part of the bottom in the front of your ship,and one in the back. Remember: Don’t punch all the way through. Glue around these, also.
Step 10. Next, take one of the pieces of cocktail stick you cut off earlier and stick it into the front of your ship at an angle, then one at the back.
Step 11. Next, mix up some PVA glue and use it to paste on small pieces of tissue paper on all the joints on both sides of your ship. Make sure to seal them well!
Step 12. When the glue and tissue paper have dried well, you can paint your ship! You can paint it all one color or add as much detail as you like.
Step 13. Next, let’s make some sails. Cut out three large triangle shapes from white paper. You’ll need five in all: three large and two small.
Step 14. Glue one large sail to each of the cocktail sticks in the middle of your ship.The two small sails you can glue to the short cocktail stick at the back of your ship.
Step 15. Finish off with a small flag on the cocktail stick at the front of your ship. If you put a small dab of glue on the top of each mast, you can use thread as rigging.
Step 16. When everything has dried, trim off any excess….You have built your first pirate ship!
And that is how to build a cardboard pirate ship.
Warning: If you use super glue and get it on your hands, dab with a paper towel, wash with warm soapy water. Handle scissors with care.
