Default 2015 Jarosch Cup Rules

String Cheese Splashdown
The 2015 Jarosch Cup contest is a spot landing competition open to rockets with motors up to and including F class.
The payload is a 1 ounce water tight sealed package of string cheese.
The length of the package is approximately 5 inches and the diameter is about ¾ inch. It should fit in any body tube BT 20 or larger.
The target will be the X in the middle of a semi-scale model of the Spacex floating landing pad known as the Autonomous Spaceport Drone Ship (ASDS). The model ASDS will be floating in the lagoon located to the east of the Launch Control Officer table. The diameter of the yellow ring around the X is 14 inches. The outer white ring diameter is 24 inches. The dimensions of the model landing pad are 30 x 48 inches. The target will be anchored at a point approximately 20 feet from the west, north and south shores of the lagoon.
The objective is to land the rocket and/or payload on or near the X on the floating platform and to safely return it to the contest judges’ station. The safe recovery of the rocket may be accomplished by means of the skillful casting of a “grappling hook” with a conventional fishing rod by the flier or a member of his/her recovery team. Recovery equipment will be provided as needed. Failure to return the rocket will result in disqualification.
Scoring will be based on the distance of the landed rocket from the X on the ASDS measured by a contest official in feet.
Any rocket landing on the field around the lagoon will be measured from the landing point to the closest point at the edge of the water plus the 20 foot distance to the target.
Any Recovered Water Landing will be awarded a BONUS in the amount of ½ the distance from the point of splashdown to the target.
Any Direct Hit on the Floating Launch Pad WINS immediately. GAME OVER!
To insure the safe recovery and fair judgement of all contest flights contestants must notify contest official at the contest registration table prior to launch. The attempt must be noted on the flight card and announced by the LCO. There is no limit to the number of splashdown attempts that can be made by an individual contestant.
Additional Comments and Tips:
1. Keep it simple and fun.
2. As the object is to land the rocket on a floating target some design consideration should be given to build material(s) that are buoyant and/or waterproof.
3. Some skill at rocket retrieval (casting) technique is advised.
4. Questions regarding rules and qualification are to be directed to the contest officials.
5. The decisions of the judges are final.
6. Arguing with judges regarding rules and/or decisions may result in disqualification.
7. See Comment 1
