The Rules

  1. Everyone is welcome to take part in this event, except for professional river guides. (referee discretion)
  2. All boat owners must transport their boat to and from the river.  Owners are responsible for all flotsam and gear adrift. Keep the river clean!
  3. NO Pre-Manufactured Boats.  The boat must be made by the competitors specifically for the event. You may not use, as the foundation of your craft,  a boat or watercraft that has been made by a factory or company with the purpose of navigating any form of water (lake, river, ocean, pond, river, brook, bathtub, pool).  Participants must be above the waterline. No enclosed tops to the boats. Boats must be kept in the water at all times. Only homemade sails and paddles are allowed. No unsportsmanlike conduct is allowed between boats.  Boats must be no wider than 6 feet and must fit under the bridges.
  4. Boats must be able to hold at least three people.
  5. All people who start the race on the boat must finish the race on the boat. (A person may fall off and get back on).
  6. Must be human-powered.  No motors.
  7. The boat must remain intact from start to finish.  A boat that breaks apart during the race will be disqualified.
  8. The event will be judged by the crowd.  This is not a timed event. Winners will be determined by the amount of audience participation they garner.  
  9. The start of the race is “green gate.”  The end of the race is the “play wave” just upriver from “river-station” take out.
  10. All on-river participants must sign a waiver, and wear proper safety gear.  A helmet and a life jacket are required, no exceptions.
