The following section is where free form comments are added and attachments are made. HOMOLOGATOR'S REMARKS Give details of any variations of IWSF rules. List any alterations to the course, etc. during the competition. List any malfunction of equipment. Give any further information which might affect the Tournament Council's assement of the homologation. 7. Posting of Homologation Notice was overlooked. 12. Slalom towers were originally reported by the surveyor to be at TNL 38.2 and TFR 39.5 degrees, which puts both towers outside the 41 - 47 degree limits of the rules; however, further examination disclosed that the readings had been taken to the front centre of the towers. In the case of TFR, the 41 degree line actually ran across the diagonal of the 2.5m square tower and thus the judges, by sitting to the rear of the tower as is natural, had their heads within the limits required by the rules. Likewise, a reading taken to the middle of the platform would comply. TnL however, is irredeemable and will need to be moved to allow the site to meet homologation requirements. It is planned to do this prior to the next tournament. Otherwise the slalom towers are OK. Ht good; sight perfect. Because of the incorrect angle of TNL the event was rated as 'N' however it is hoped that the technical committee may consider an exemtption to allow the scores to be submitted. It is noted that a narrower angle of veiw tends to increase the chances of a false zero on the gates and so is a disadvantage to the skier. The only other problem with the slalom event was that one of the pre-gate buoys was out of tolerence for the 55m distance which makes no difference to performance. 16. Trick tower only about 1.5m above the water surface. Trick cameras on scaffold about 4m. 16a. both 5 judge and 3 judge set ups were used at varius itmes during the tournament. Jump system The Boetcher video jump measeurement system was used. Though the survey xy coordinates of hte 40 and 60m check buoys were available, Only check distances were available from the video system. These compared within the 150mm tolerance for "L" homologation as follows:- 40m survey = 39.76 video = 39.89 diff = 130mm OK 60m survey = 59.57 vidoe = 59.72 diff = 140mm OK All other matters pertaining to the jump event were satisfactory and it was therefore recommended for "L". Further comments about course accuracy. If the survey figures provided at the end of this dossier are examined in Emanuel Lion's Homologation program the jump element will display some errors. These are:- 1) 15st - 210m =14.67 ideal 15.00. In this instance the program only allows a tolerance of 150mm but the rules allow a tolerance of 500mm. The course is satisfactory. 2) 15st - 180m = 14.62 ideal 15.00. As above the program tolerance does not agree with the rules and the course is satisfactory. 3) Ramp - 15EC =15.179 ideal 15.00. In this instance the calculated width is 29mm out of tolerance. However the calculated width is dependent on the centreline that is chosen. In this instance the program appears to be correct, however if the same fugures are placed in Dave Clark's spreadsheet, which uses a least squares centreline, then the width figure for 15 EC is satisfactory. Although the method of selection of the centreline in the spreadsheet is not strictly in accordance with the rules, which require the line 15st -15mt to be adopted, Dave's spreadsheet has been accepted for many years so it is submitted that the position of 15EC is acceptable. This discrepency between the adopted centrelines between Emanuel Lion's program and Dave Clark's spreadsheet appears also in the slalom course figures where Emanuel's program throws one additional error being the width of P1. Axe - P1) In this instance the adoption of the least squares centreline is within the rules as th rules are not so definite for slalom. Copies of the spreadsheets are available for perusal if required.
