2023 RULES

  1. The entire boat must be built of cardboard.
  2. Cardboard may be as thick as you want and may be layered together.
  3. Cardboard carpet tubes or similar tubes may be used. Duct tape, masking tape, wood glue or contact cement may be used. Metal or plastic staples, clamps, nails, screws, etc, may NOT be used. “Sono-Tubes or any other type of pre-treated or coated cardboard that has been processed in such a way as to waterproof the cardboard may not be used.
  4. Boats may be painted with water-based paint or water sealer like Thompson’s Water Seal Stain. All paint and stain must be dry before the boat enters the water. Tar, wax, silicone, fiberglass resins, epoxy glues or Styrofoam are prohibited.
  5. Raft style designs may be used, but surfboard-style designs may NOT. The distinguishing features of the raft design over that of a surfboard is the use of connected cardboard logs.

  8. No electrical power sources will be allowed on any boat once in contact with the water.
  9. If there is any doubt about the construction, the judges reserve the right to use a probe, such as an ice pick to test and verify that only cardboard has been used. Construction violations discovered during any part of the day shall be cause for elimination.
  10. Life Jackets must be worn during the race.
  11. Each team is responsible for disposing of their boat after the race.
