Note that Moun-tain Daylight Time runs from March 11 to November 4, 2018, inclusive and that GNCTR 2019 will take place during Mountain Standard Time. Submissions must be submitted electronically in PDF format by the dates specified in Section 4.4. Required submission documents include a Safety Report, Project Schedule, and Technical Report. Competing teams are required to submit two (2) concrete test cylinders of their final mix design(s) in addition to the required documents. The test cylinders should be ground and ready for compression testing. Submit all Technical Reports to the VP Technical (Mark Curley) via email at [email protected]. One (1) bound hard-copy of the Technical Report shall be submitted upon arrival at the designated team registration timeslot. The 11x17 drawing package may be submitted as a separate bound document in conjunction with the Technical Report. Teams are not required to submit hard-copies of the Safety Report or Project Schedule.

4.1 SAFETY REPORT

All teams that intend to ride a Toboggan must submit a brief report outlining the compliance of the team’s Toboggan design with the requirements outlined in Section 6. Teams should specifically highlight considerations affecting the rider safety during race activities, including but not limited to, racer configuration and protection, effectiveness of mechanical systems, and special provisions to pro-tect the racers in the event of a crash.

The purpose of the Safety Report is to outline the general concepts and specific measures to reduce risk of injury during race activities, rather than provide de-tailed technical justification for the design approach. Common reasons for Tobog-gan crashes or injuries have been identified from past competitions, and are list-ed below. In the Safety Report, teams should specifically describe the measures they have taken to avoid these problems when racing:

Over-Steering causing crash into side barrier or tipping; High center of gravity causing lateral instability; Concrete skis/slab edge digging into snow, leading to tipping; Ejection of front riders during the run; Adequately safe seating capacity for five riders.

The Safety Report should not exceed 1,500 words in length, excluding appendi-ces. Construction drawings for the Toboggan must be submitted with the Safety

i.ii.iii.iv.v.



Report as an appendix. The drawings must be of sufficient quality that reviewers can clearly evaluate the effectiveness of the design and identify potential risks to racer safety. The Safety Committee will review all Safety Reports submitted by the prescribed deadline, and feedback will be provided to teams no later than November 9, 2018. Earlier submissions will be accepted; please allow up to two (2) weeks for review.

The Safety Committee reserves the right to request a response to all or part of the feedback given with the Safety Report review. If a response to feedback is required of a team, they must submit their responses to the Safety Committee no later than 11:59:59 PM on the date falling two (2) weeks after the feedback is giv-en. Late submission of responses to Safety Committee feedback will be subject to the same point deductions from the team’s competition score as prescribed for late submission of the Safety Report (Section 4.5.2). If any team fails to sub-mit a Safety Report or a response to Safety Report feedback prior to the Safety Inspection as part of the Technical Exhibition, the team will not be permitted to participate in Race Day activities.

4.2 PROJECT SCHEDULE

All Competing Teams are required to submit two Project Schedules (baseline and actual). The intent of the Project Schedule is to aid and evaluate the team’s abili-ty to plan, monitor, and manage their design and construction schedule. This will help provide Competitors with experience relating to unpredictable schedules and project delays. The baseline project schedule shall be submitted to the Or-ganizing Committee by the earlier of: (a) Construction commencement; or (b) the deadline prescribed in Section 4.5.

The Project Schedule must be completed in Gantt chart format with critical path denoted in red. The Project Schedule work breakdown structure must include for each task or milestone:

Activity ID; Activity description; Activity duration; Baseline start and finish; Actual start and finish; Start and finish variance.

PART 6 - TOBOGGAN REQUIREMENTS 18


All Toboggan and component designs submitted to previous competitions are considered to be in the public domain and are valid to be replicated by Com-peting Teams, on condition that proper technical justification is provided and evidence of new construction is demonstrated in the technical documents. Any team presenting design calculations that the Judges deem to be insufficient or technically flawed will be subject to a thorough Safety Inspection and may be de-ducted points for Toboggan design and/or prohibited from racing. Teams should use commonly accepted engineering practices in developing design loadings and in calculation of Superstructure member capacities.

6.1 SAFETY

The Toboggan must be able to safely and comfortably accommodate five (5) rid-ers. Teams must be able to demonstrate this at the Technical Exhibition and during all pre-race Safety Inspections, if requested. There must be clear space for roll protection (50 mm minimum) between the top and sides of the helmet of the tallest rider and the inside of the roll cage. The bottom and sides of the Toboggan must be enclosed to ensure no part of any rider is outside of the Toboggan during the Run. The Toboggan’s Superstructure should contribute to enclosure such that the frame and/or tubing are arranged in a manner that prevents rider ejection. Supplemental materials such as plexi-glass, snow fence, or other suitable means can be used (and are recommended) to help contain rider limbs throughout a Run. Refer to Section 2.2 for more details on the definition of Enclosure. The Toboggan’s Enclosure will be reviewed and must be deemed sufficient by the Safety Commit-tee to contain the riders prior to the start of a Run. The rider’s seating area shall be flat and free from bolts, frame members or other protruding objects. No sharp objects are permitted inside or outside of the Toboggan. All frame components enclosing the riders shall be padded with foam (6.5 mm minimum thickness).

Hand grips must be provided for all riders. T-bars or other frame members imped-ing forward movement of the rider are prohibited. The front of the Toboggan and associated frame members are exempt from this requirement. Individual rider seats may be utilized, but seat backs must be padded to protect rearward riders in the event of a collision. Seats must be securely fastened to the Toboggan. Seats and mounting system shall be designed to accommodate forces exerted during a collision. No restraint system which connects riders to the Toboggan may be used except if the individual harness is a five-point style meeting the requirements of the National Hot Rod Association (NHRA) drag racing requirements. Harnesses shall be securely mounted to the frame, with both the mounting system and

6 TOBOGGAN REQUIREMENTS



6.2 WEIGHT

TThe Toboggan shall weigh no more than 136 kg (300 lbs) in its unloaded racing configuration. Note that this maximum weight is less than recent years’ compe-titions, but has been the standard for many years prior. This configuration must include all safety equipment specified in the Safety Report and identified by the Safety Committee during the review of the Safety Report. Additional material may be added to the Toboggan in excess of the 136 kg weight limit (up to a maximum of 4.54 kg (10 lbs) additional weight) for necessary modifications identified during the pre-race Safety Inspection, only if the requirements had not previously been identified to the team by the OC in review of the Safety Report.

Overweight Toboggans, up to a maximum of 202 kg (445 lbs), will be permitted to race. Overweight Toboggans will be penalized two (2) points plus one-half (0.5) point per kg over the limit (rounded up to the nearest half kilogram) from their overall score. If a team’s Toboggan exceeds the prescribed maximum weight, the OC may permit it to race, but the Toboggan will receive a score of zero (0) for their total Toboggan Design (See Table 4).

The Toboggan must have an attachment point for a tow cable to pull the Tobog-gan to the top of the race hill. A 50 mm (2”) minimum diameter eyelet, U-bolt or similar mechanism is typically required for this. Teams should demonstrate in their Technical Report that this attachment point is appropriate for forces gener-ated from towing up the incline. Teams that do not provide an attachment point will not be transported to the top of the hill and will not be able to race.

6.3 RUNNING SURFACE

The Toboggan’s Running Surface must be comprised entirely of concrete. All con-crete used in Toboggan construction must be comprised of cementitious materi-als containing a minimum of 30% Portland cement by mass. Ski wax is the only permissible coating for the Running Surface. The type used and method of ap-plication must be clearly indicated in the Technical Report. A concrete patch mix used to skim coat the Running Surface to fill honeycombing, bug holes, or other voids is permissible such that the following criteria are met:

The mix must be non-structural in nature (i.e. is used to smoothen the Running Surface only);

i.

ii.

frame designed for the forces exerted during a collision event. Steering Systems must have a maximum stroke and/or limiter device to prevent oversteering during the course of a Run.



Technical data for the patch mix must be included in the Technical Report, including product used and application; Photos documenting the entire application process must be included in an appendix of the Technical Report. This must include photos of the concrete skis prior to application showing the voids that are being filled. Photos should also document that the cross- sectional dimensions of the Running Surface have not significantly changed due to a thick patch mix being applied; It is permissible for the patch mix to be either designed and batched by the team, or be a readily available commercial concrete patching product.

If a team uses a product to patch their Running Surface the team must submit a technical data sheet for the product to the GNCTR 2019 Organizing Committee for review prior to use in construction.

Teams should explicitly calculate the capacity of any connections of the super-structure to the concrete Running Surface and demonstrate that the capacity exceeds likely demand during all foreseeable race conditions.

Details of Running Surface preparation must be described in the Technical Report. This includes grinding, waxing or other modes of preparation teams use to facili-tate completion of the Toboggan Running Surface.

6.4 SUPERSTRUCTURE

The Toboggan must have a Superstructure which can act as a roll cage to with-stand any foreseeable crash impact and protect all riders. Teams must clearly state in their Technical Report all assumptions made in preparation of design cal-culations for loads and resistances, with justification for any load or resistance factors used. Teams are required to justify all design cases in the technical report. The following should be accepted by all teams as minimum crash or impact cases to be considered in design of the Toboggan Superstructure:

Front or Rear Impact at 65 km/h design speed; Roll-over impact at 75% of the design speed; Side Impact into crash barriers at 50% of the design speed.

6.5 MECHANICAL SYSTEMS

The Toboggan must be equipped with fully operational Braking and Steering Sys-tems. These are mandatory to meet safety requirements as well as to score full points in Toboggan Design.

iii.

iv.

i.ii.iii.



6.5.1 Braking SystemThe Toboggan must have a Braking System capable of safely bringing the Tobog-gan to a stop in a reasonable distance at the end of each Run. Any portion of the Braking System that could act on the snow and generate stopping force shall not be placed forward of the Toboggan’s centre of gravity. Gravity powered brakes shall not exclusively utilize rider weight to provide downward braking force. De-signs which utilize the overall Toboggan and rider weight may be permitted pro-vided they meet the safety requirements of Section 6.1 and they do not adversely affect rider safety.

6.5.2 Steering SystemThe Toboggan must have a Steering System. The use of weight-shift steering is permitted, but only as a secondary measure to supplement a deliberate mechan-ical Steering System. The Steering System must have over-steer protection (see Section 6.1) and information regarding a Steering System that is in contact with the snow can be found in Section 2.2.

6.6 CONSTRUCTION

All competing teams must construct an entirely new Toboggan, containing no part or component which has been used in construction of a previously submitted concrete Toboggan, with the following exceptions:

The repurposing of salvaged raw materials such as individual lengths of roll frame tube is permitted;Salvaged material may also include shocks or parts for a rack and pinion Steering System, for example, provided the salvaged com-ponents are not damaged and are fit for use. Teams are required to indicate any repurposed materials in their Safety Report and provide evidence that the materials are fit for use. Teams will be required to demonstrate the functionality of any repurposed items during the Safety Inspection.A team may repurpose all, or part of, a Toboggan Superstructure that was submitted to a previous competition by the same Univer-sity or College. This may only be done if sufficient justification is provided to the Organizing Committee. One possible justification is significant effort to improve on a previous superstructure design by modification. Teams are highly encouraged to seek approval from the Organizing Committee prior to proceeding with design and con-struction using a repurposed Toboggan Superstructure. Under no circumstances will a Toboggan Superstructure be permitted to be used for more than two competitions. Teams which elect to repur-

i.

ii.

iii.



pose a prior Superstructure without significant effort to modify or improve may only receive partial points for Superstructure design.

Non-Competing teams may re-use a Toboggan from a previous competition, pro-vided it is deemed safe to operate through the team’s own analysis and genera-tion of a Safety Report for review by the Safety Committee. Non-Competing teams may not be required to modify their Toboggans to conform to current Rules, pro-vided the Toboggan was in accordance with the Rules at the time of its first use. All competing Toboggans must be constructed exclusively by the team with doc-umentation of the construction process provided in the Technical Report and with the Technical Display. The contracting of specialized work, such as welding or work deemed too severe of a safety risk, is permitted if the team can provide evidence the work was performed by a certified technician.

6.6.1 Welds and ConnectionsFor the GNCTR 2019 Competition, any team(s) designing and building a new to-boggan shall provide technical details and evidence on how Superstructure joints were connected. A more thorough evaluation of Superstructure connections is a new aspect of the Competition in 2019 that considers weld design and weld competency. Weld design and welder qualifications will not have an impact on a team’s Superstructure score.

Technical details shall include documenting weld procedure, drawings of the con-nection, and required strengths of joints in the Toboggan Superstructure. If this information is available to Non-competing or Alumni teams, the OC requests that this information is included with any Technical or Safety Report submissions. Connections or welds shall be completed such that the required strengths indi-cated in the technical details and design drawings are achieved. Teams shall pro-vide proof of adequate connection or weld strengths through one of the following options:

Teams use a professional welding shop to have the welding com-pleted by a certified technician who is qualified in an approved weld procedure. The shop name and technician’s journeyman or Red Seal stamp must be provided in the appendices of the Safety Report and Technical Report. The welder must be qualified in the method and materials being welded following CSA W59-13 for weld-ed steel construction (metal arc welding), and/or CSA W59.2-M1991 for welded aluminum construction;Teams complete the welding themselves and provide evidence of weld competency through means of destructive and non-destruc-tive testing with spare material on sample connections similar in design to those used in the Toboggan Superstructure. Destructive

i.

ii.



tests that shall be conducted on the samples are tension test, bend test, and Charpy test. Non-destructive testing that shall be completed on the sample is ultrasonic testing (UT). If a team per-forms the welds themselves they must be supervised by a welding professor, technician, or certified journeyman. Ideally, the team’s tests should be on the spare material and are reviewed by the competent person as well;Other means of connecting joints and testing joint strength deemed acceptable and approved by the OC.

If a team elects to contract the welding work to a shop, the shop and technician’s name performing the welds, along with the weld procedure, must be provided to the OC at least two (2) months prior to start of the Competition. The weld shop should be certified to CSA W47.1-09 for steel welding and CSA W47.2-11 for alumi-num welding.

Teams electing to perform their own welds under the supervision of a qualified person shall provide the OC with the qualified person’s name and credentials at least two month(s) prior to the start of the Competition. Proof of destructive and/or non-destructive testing shall be provided to the OC at least one (1) month prior to the start of the Competition. Weld procedures and design shall meet CSA W59-13 or CSA W59.2-M199 for steel welding or aluminum welding, respectively.

Teams that connect the Superstructure joints via methods other than welding shall provide details on the method of connections and evidence validating the strengths of the connections at least two (2) months prior to the start of the Competition.

PART 7 - TOBOGGAN INSPECTIONS 24


7 TOBOGGAN INSPECTIONSAll Toboggans will be subject to a Safety Inspection by the Safety Committee. The official Toboggan weigh-in will occur following a successful Safety Inspection. The Safety Inspection will be completed during the Technical Exhibition. The Safety Inspection order will be announced prior to the Technical Exhibition day and the Organizing Committee will endeavour to ensure inspections do not conflict with the Technical Presentations.

Teams which fail to attend their scheduled Safety Inspection will be deducted two (2) points from the team’s total score. Teams that do not pass their Safety Inspection or are found to exceed the maximum Toboggan weight limit will be permitted to make modifications to their Toboggan and have their Toboggans re-inspected and/or re-weighed following the scheduled Safety Inspections, on a first-come, first-served basis.

Any Toboggan that does not pass the Safety Inspection and fails to make revisions as per the requirements of the Safety Judges, or fails to pass the subsequent re-inspection, will be prohibited from racing. Toboggans must be re-inspected and weighed following any modifications that are made after the initial Safety Inspection. Such modifications include, but are not limited to:

Changes to Steering and Braking Systems; Replacement or modification of the running surface (including slabs and/or skis); Changes to the rider safety features; Addition or removal of any components.

Toboggans must be re-inspected by a member(s) of the OC or Safety Committee after any Crash that occurs during Race Day Runs before being permitted to race again. Following the Safety Inspection and weigh-in, no further modifications to the Toboggan will be permitted without the knowledge and permission of the Judges and Safety Committee.

Any team caught racing or attempting to race without having their Toboggan re-inspected following modifications or a Crash will be penalized at the discretion of the organizing committee, up to and including disqualification from all remain-ing races and the forfeit of all points earned during Race Day.

PART 8 - TECHNICAL EXHIBITION 25


All Competing Teams must be present at the Technical Exhibition and adhere to the requirements of this section. Teams are prohibited from performing any modi-fications to the Toboggan which could damage the facility, such as grinding, paint-ing, waxing etc., on the premises of the Technical Exhibition. All Team members are required to be knowledgeable about the design and construction of the Tobog-gan and should be capable in answering any questions that the Judges may ask.

8.1 TECHNICAL DISPLAY

Each Competing Team must present a Technical Display showcasing their Tobog-gan and design process. The Toboggan and any parts to be used during the race must be present at the Technical Display. Design and aesthetics of the Technical Display shall incorporate the team theme. Spirit Judges will judge the Technical Display for relevance to the team theme.

Each Team must have at least three (3) team members present at their display for the duration of the scheduled Technical Exhibition. All team members are expected to respond to basic questions about the Toboggan design and construc-tion during the Technical Exhibition, and to direct Judges to an appropriate team member to defer in-depth technical questions to.

Each team will be allotted a space within the Technical Exhibition venue to dis-play their Toboggan and Technical Display. Teams will be given two (2) adjacent 3 m x 3 m (~10 ft x 10 ft) areas, which must entirely contain the Toboggan display and the Technical Display, respectively. Note: This provision of display areas is subject to change upon final confirmation with the exhibition venue and will be confirmed on the GNCTR 2019 website.

Only the Toboggan and additional parts to be used on Race Day may be displayed within the Toboggan display area. A raised platform for display of the Toboggan will be permitted. Each team must provide floor protection for both the Technical Display and Toboggan display area. Teams not supplying floor protection may not be permitted to set up their Technical Display. A rug or similar material is typical-ly sufficient floor protection.

Technical Displays shall be limited to 2.5 m (~8.5 ft) in height. Technical Dis-plays containing an accessible suspended floor must comply with applicable local building codes regarding the construction of temporary structures. All multi-level structures or structures which may cause a life/safety hazard are required to have proof of adequate design. Any team’s Technical Display that features interactive

8 TECHNICAL EXHIBITION

PART 8 - TECHNICAL EXHIBITION 26


activities must be displayed in the Technical Display section and not alongside the Toboggan display. Food is not permitted as part of a team’s Technical Display. However, if a team intends to have food as part of their display setup, the food item must be in conjunction with venue protocols and approved by the OC at least one (1) month prior to the start of Competition.

The Organizing Committee reserves the right to prohibit the use of structures which violate any criteria outlined herein.

8.2 TECHNICAL PRESENTATION

During the Technical Exhibition, teams will be required to provide an informal safety presentation to accompany the Safety Inspection. The presentation is to be delivered in English. The intention of this is to highlight risks inherent to the design and how the team has mitigated these risks. Performance in this presen-tation will contribute to the overall safety score allocated to the team.

Each Competing Team will conduct two (2) separate formal presentations on the design features of their Toboggan. Teams will select up to three (3) represen-tatives to present on their concrete mix and concrete reinforcement, and up to three (3) different representatives to present details on the Toboggan’s Super-structure, Steering, and Braking Systems.

Presentations will be scheduled during Technical Exhibition. Teams will be pro-vided with the schedule prior to the Technical Exhibition. Presentations will be strictly limited to five (5) minutes of presentation followed by five (5) minutes of questions from the Judges. Presentations will be judged on the technical content, presentation quality, and communication skills of the presenter(s).

A projector and laptop will be provided in each presentation room for the use of the presenters. Any presentation slides must be in Microsoft PowerPoint format. Competing teams must also provide a link to their presentation on a cloud based site and save the final presentation on a USB key. A brief preparation period prior to the presentation will be provided to permit teams to familiarize themselves with the presentation rooms and upload their presentations.

Teams failing to attend their slotted presentation time will score zero on their Technical Presentation.

PART 9 - RACE DAY 27


9 RACE DAYRacing order will be selected randomly and provided to teams prior to Race Day. The Organizing Committee reserves the right to modify or exclude specific events due to weather and track conditions, time constraints, or other unforeseen circum-stances. The Organizing Committee reserves the right to remove, add, or modify race specific rules prior to Race Day due to weather and track conditions, time constraints, or other unforeseen circumstances. Any race-specific rule changes will be provided to the team captains prior to Race Day and posted at the race hill.

Riders must remain within the Toboggan during the entire Run and may not exit the Toboggan until it reaches a complete stop. If a rider leaves the Toboggan during the Run or before the Toboggan has come to a complete stop, the Run will be considered a DNF and will not count towards scoring.

If the Toboggan incurs damage during a Run (including braking) the Run will be considered DNF. The decision to use the Run for scoring purposes will be at the Judges’ discretion. The Toboggan may be repaired but must pass a Safety Inspec-tion and must be re-weighed prior to any additional Runs.

Races will take place on a snow-tube type hill. The geometry of the GNCTR 2019 race hill is shown in Figure 1, provided in Appendix B. The geometries of previous years’ race hills will be posted on the GNCTR 2019 website.

9.1 SAFETY

Riders are not permitted to be under the influence of drugs or alcohol while rac-ing. Teams caught with a rider under the influence of drugs or alcohol will imme-diately be prohibited from racing and will lose all points for Race Day activities accrued up to the time of the infraction.

Teams must adhere to the safety requirements for the Toboggan as described in Section 6.1. All riders must have a fitted, unmodified, and certified (DOT, SNELL, or equivalent) snowmobile or motorcycle helmet and be wearing it as instructed (chin straps secured) until they have safely left the racetrack. All riders must have themselves and all their limbs inside the Toboggan Superstructure at all times during the Runs. Riders are not permitted to stand at the rear of the Toboggan.

The boundaries of the racetrack will be clearly marked. Spectators (anyone not riding a Toboggan) are not allowed on the racetrack at any time. Violation of the Rule by any member of a team may result in that team’s disqualification from Race Day. Competitors are expected to be dressed in an appropriate manner for



the race. Costumes are permitted and encouraged, but must accompany suitable winter attire. The starting official may direct participants to change their attire prior to a Run.

Toboggans are to be transported up the hill via tow rope and snowmobile. Only one (1) rider is permitted on the Toboggan during transport up the hill (must be wearing a helmet) strictly for steering purposes. The Braking System needs to be restrained during tow. If this is not possible, the sled must be pushed up the hill.

9.2 STARTING

A team and their Toboggan must be present in the start staging area at least five (5) minutes before the start of their Run. Failure to do so may result in the team forfeiting their Run. Teams must not start their Run until directed to do so by a Race Official.

Each team is permitted to have two (2) members from their team help push their Toboggan at the start of the Run. In the event the team does not have sufficient members available, Volunteers may be employed from the start staging area to help push the Toboggan. The pushing start line will be identified on the hill at Race Day. The front of the Toboggan must be in front of the identified pushing start line at the beginning of the push start. If the hill is found to be too fast (decided prior to competition by OC during test Runs) the starting point may be adjusted to reflect safety concerns. The OC may implement a ‘no-push’ mandate in which case the team members or volunteers assisting the Toboggan riders must simply let go of the Toboggan during the start.

The riders on the Toboggan may not help push the Toboggan. The designated pushers must push against the superstructure and not on the riders. Pushers shall commence their pushing efforts while in contact with the Toboggan. Run-ning starts are not permitted. The pushers must release contact from the Tobog-gan prior to the rear of the Toboggan crossing the start line and make a reason-able effort to not cross the start line themselves. Failure to do so may result in the Run being marked DNF at the discretion of the Race Officials and Judges.

9.3 CRASH

Refer to Section 2.2 for the definitions of ‘Crash’ and ‘Did Not Finish’ (DNF).

In the event of a Crash, no attempt to continue the Run shall be made, and the riders will be expected to safely leave their Toboggan and transport it to the bottom of the hill. If a Toboggan stalls during a Run, but is otherwise in upright



position and facing downhill, the Run will be recorded as a DNF. However, the team will be permitted one opportunity to have their designated pushers restart the motion of the Toboggan to reach the finish line. If the Toboggan subsequently stalls a second time, the Run shall be abandoned, and the riders must exit the Toboggan and safely transport it to the bottom of the hill.

Teams that successfully complete the race course by crossing the finish line, but fail to stop the Toboggan within the designated braking area, will not be record-ed as DNF, but will receive a braking score of zero (0) for the Run. Any Toboggan involved in a Crash or fails to brake in the designated area must be reviewed by the team, and is permitted to be repaired as required. If a team intends to continue to use a Toboggan that has crashed or experienced a braking failure, it must be brought to the Safety Committee for re-inspection prior to attempting subsequent races.

9.4 RACE EVENTS

Race Day will consist of three (3) major events: Drag Race, Slalom, and King of the Hill. A braking event will not be scheduled separately. Instead, a team’s braking performance will be determined from their best result between the Drag Race and Slalom events. Points for braking performance are specified in Section 9.5.4. If a team feels uncomfortable with a speed they reach travelling down the hill, it is acceptable to activate their Braking System part way down the Run, providing it is not a one-and-done system (i.e. pneumatics). No deduction will be recorded for early brake deployment in this case due to the following reasons:

As outlined in Section 9.5.4, Braking Performance is measured via deceleration, not total braking distance. Any slight advantage from early brake deployment would be offset by the following;

Any team deploying their Braking System early will be sacrificing run time and top speed scoring, which is deemed enough of a con-sequence for early deployment.

9.4.1 Drag RaceThe race course will be set up with three sets of gates, oriented in a straight line. At the base of the Run, there will be a designated braking area defined by the finish line and a barrier constructed some distance beyond the finish line.

The object of this Run is to complete the course in the shortest time possible, while passing through each gate without contacting the gate markers, and to stop the Toboggan within the braking area as quickly as possible. Each team will be permitted one attempt to complete the Drag Race course.

i.

ii.



9.4.2 Slalom The race course will be set up with three sets of gates staggered laterally across the width of the course. At the base of the Run, there will be a designated braking area defined by the finish line and a barrier constructed some distance beyond the finish line.

The object of this Run is to complete the course in the shortest time possible, while passing through each gate without contacting the gate markers, and to stop the Toboggan within the braking area as quickly as possible. Each team that successfully completed the Drag Race course or recorded a DNF in the Drag Race course, and subsequently passed a safety re-inspection, will be permitted one attempt to complete the Slalom course.

9.4.3 King of the HillThe King of the Hill tournament Runs will commence after the conclusion of the Drag Race and Slalom Runs. Any team which successfully completes at least one of the Drag Race or Slalom event, and has passed any necessary safety re-inspec-tions, will be entered in the King of the Hill tournament.

Teams will be seeded for the tournament based on ranking of their fastest com-pleted run in either the Drag Race or Slalom event. The tournament bracket will be posted at the racing area prior to the tournament start. The race course will be cleared of any gates. Two (2) teams will race down the hill simultaneously in sep-arate lanes. The team whose Toboggan crosses the finish line first will advance to the next round. A Toboggan is across the finish line when the front-most portion of the Toboggan proceeds over the line, marking the conclusion of the race.

Teams which Crash or do not cross the finish line will have the Run considered DNF and will not continue in the tournament. Should both Toboggans Crash during a head to head race, both Toboggan Runs will be considered DNF and both teams will be eliminated from the tournament.

The tournament follows sudden death format. In the event of an odd number of teams competing in the tournament, the team with the fastest recorded Run time from throughout Race Day may be granted a ‘bye’ to the next round of the tournament at the discretion of the Race Officials.

The winner of the last tournament race is crowned “King of the Hill”. Non-Com-peting Teams will be permitted to participate in a separate King of the Hill com-petition following the same rules, if time permits.

If no team makes it down the hill, the four (4) teams with the fastest recorded run times from throughout Race Day (Drag Race and Slalom events) will attempt the race again in a sudden death format, where the team that wins twice will be crowned King of the Hill.



9.5 SCORING

9.5.1 Top SpeedThe fastest Run time for each team shall be the lesser of the Run times recorded for the Drag Race and Slalom events. Points will be awarded to any team that completes at least one of the Drag Race or Slalom Runs. If a team fails to com-plete either of the Runs, they will be awarded no points.

Points will be allocated based on a team’s fastest Run time relative to the fastest and slowest recorded Run times by all Competing Teams. The following formula will be used to calculate the points awarded to a team:

9.5.2 Steering PerformanceSteering performance will be judged in both the Drag Race and Slalom events. Although the Drag Race is a fastest time event straight down the hill, a Toboggan must show the capability of travelling straight or correcting minor deviations inherent in the steering.

Points will be awarded to any Competing team that participates in the Drag Race or Slalom Runs, with a preferential point distribution towards the Slalom event. If a team fails to complete a full Run, but makes it through one (1) or two (2) of the first three (3) gates in the Slalom event, the team shall receive partial points based on the rubric below.

Contact with any part of the gates results in a one (1) point deduction, per oc-currence. Any Toboggan that misses a gate completely will be two (2) points, per occurrence. Any Toboggan that strikes a barrier of the course will be deducted three (3) points, per occurrence. A deduction of six (6) points will be assessed to any Toboggan that is involved in a Crash during a Run.

9.5.3 King of the HillAll teams that participate in the King of the Hill tournament will receive points. Any team which does not qualify for the King of the Hill tournament will receive no points. The winner of the tournament will be awarded a full 7.5 points, and the runner-up will be awarded 6 points. Teams which are eliminated in rounds

Points will be awarded to any Competing team that participates in the Drag Race or Slalom Runs, with a preferential point distribution towards the Slalom event. If a team fails to complete a full Run, but makes it through one (1) or two (2) of the first three (3) gates in the Slalom event, the team shall receive partial points based on the rubric below.Table 5. Steering performance points distribution

Contact with any part of the gates results in a one (1) point deduction, per occurrence. Any Toboggan that misses a gate completely will be two (2) points, per occurrence. Any Toboggan that strikes a barrier of the course will be deducted three (3) points, per occurrence. A deduction of six (6) points will be assessed to any Toboggan that is involved in a Crash during a Run.

prior to the final race will be awarded points based on a tiered system that is established at the time of setting the tournament bracket. The point system will be calibrated to award 5 points to semi-finalists and 1 point to teams eliminated in the first round.

9.5.4 Braking PerformancePoints may be awarded to any team that completes at least one of the Drag Race or Slalom events. If a team fails to complete either of the Runs, they will be award-ed no points. Only Runs in which braking is attempted will be graded for braking performance. The braking score will be based on the calculated deceleration of the Toboggan. The Toboggan speed will be recorded at the crossing of the finish line. The stopping distance will be measured from the indentation in the snow where the brake was first applied to the brake location in the Toboggan’s final resting place. The rate of deceleration will be calculated for each Run using this informa-tion. If a Toboggan fails to stop within the specified braking area, the Run will be considered a braking failure and zero points will be awarded for the Run.

Points will be allocated based on a team’s average acceleration relative to the highest and lowest average accelerations. The following formula will be used to calculate the points awarded to a team:

awarded a full 7.5 points, and the runner-up will be awarded 6 points. Teams which are eliminated in rounds prior to the final race will be awarded points based on a tiered system that is established at the time of setting the tournament bracket.
