Step 1: First draw the outline of the bottom of the pirate ship, and draw round windows on the outer wall of the ship and a large anchor hanging at the stern.
Step 2: Then draw three vertical masts upwards, and draw sails on the three masts respectively. Draw the pirates skull logo on the sail on the mast in the middle.
Step 3: Finally, paint the outer wall of the ship brown, paint all the sails black, leave the skull logo blank, and a simple sketch of a pirate ship is ready.
