Compete in one of two categories of KAUST’s first Dhow 3D printed Boat Race! The race will take place in the fountain in front of the university library. Due to the unexpected high number of registrations which will lead to a print volume that we will not be able to handle. we therefore changed the rules that only 1/3 (in volume) of
the boat including the propeller needs to be 3d printed and we encourage creative use of other materials (in order not to overwhelm our priniting service).
Here are the three steps to fame:
1. Create the fastest partially 3D printed design. If you need help to get started with 3D modeling attend our short introductory course. Sign up here!
2. Print it out and assemble it! If you do not have access to a 3D printer you can use our’s at the library.
Boats will start in two categories:
(A) Rubber Band Propulsion,
(B) Electronic Propulsion.
All rules are identical for both categories except otherwise noted.
The winners will take home eternal fame and a few prices!
If you don't want to be part of the competition, you are still welcome to watch.
1. Each race is a best of three runs head to head race.
One boat from each race will advance to the next level in the bracket.
2. All boats must be driven by:
- Category (A) Rubber Band Propulsion:
Elastic power only (rubber bands, surgical tubing, latex bands, etc). No electrics (other than for decoration), no combustible motors (rocket motors, fireworks, gas engines, etc).
- Category (B) Electric Propulsion:
Electric power using only one motor that is provided by the organizers of the race. Boats that use different motors will be disqualified.
3. The maximum boat size is 200mm x 150mm. Length and width of your boat will be verified at check in.
4. The course is approximately 300mm wide. Fastest boat to the end wins each heat.
5. If neither boat makes it to the end, the boat that travels the farthest will win that heat.
6. All boats must be driven by a 3d printed paddle, propeller, turbine, or screw. No slingshots, catapults, or other “shot” style locomotion.
7. Boats cannot use the sides or bottom of the race track for locomotion (it’s okay if you bump into it though). The boat should be designed to be able to work in an environment without walls.
8. Boats will start from the back of the trough but may not push off of the trough to get started. If the paddle is located on the back of the boat, the boat may be spaced by a judge to the back of the trough without the paddle touching.
9. The paddle, propeller, turbine, or screw must be 100% 3D printed.
The hulls of the boat must be a minimum of 1/3 (i.e., one third) 3D printed (judged by volume at check-in, for category (B) motor and battery are not considered as part of the boat hull).
10. Contestants cannot push or help the boat on start and cannot touch the boat after it has left the start line.
11. Each contestant will get one false start and then a judge will release the boat.
12. All contestants must be at the race for their start time. Missing your start time will eliminate you from the competition.
13. This is a fun event, any unsportsmanlike conduct will result in elimination.
14. Boats and racers cannot damage the trough as part of the race.
15. Racers must pre-register for the event. Walk up or day of entries cannot be guaranteed, but might be accepted depending on availability.
16. If there is a team, only one member can be at the trough to race at a time. The remainder of the team may watch.
17. Between each run of the race, the racers will have 90 seconds to retrieve, rewind (if necessary), and place their boat into the water at the starting line for the next race. If they go over time, they forfeit that race.
18. Please ensure that your boat is safe and you have any proper safety gear you need to operate your boat. Boats deemed unsafe by the judges may be disqualified.
19. All judges calls are final.
20. All racers under the age of 18 must have permission and must be accompanied by a parent or guardian at race time.
21. The non-printed parts of the boat can be made of any material.
Coins or tape can be used to add ballast or level the boat. Rubber bands will not be provided, and racers can use any elastic they choose
