If you’re the one entering the competition, then you should be the one to create the design, not us.

Boats love to flip over so I would make it as wide as the straws will go to make it stable. I would start with the ping balls in a pattern like the number 5 on dice. Keep the balls on the table as you build so they are even. Glue a stick up from each ball but not to high. Then the straws across like an X and straight across. May not be a fast boat but it would make a good barge.
