[section deleted] END OF HOMOLOGATION FORM It is important to leave the above section in the exact format as it will be processed automatically. 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. Final round of both Slalom and Jumping conducted after dark. Arrays of Halogen Construction Light towers were placed on both sides of the lake, in line with each of the eight gate lines of the slalom course. Additionally, the Goode Lighted "PowerBuoys" were used for Entrance gates plus all six skier turn buoys. Comments from Skiers were quite favorable. For jumping, the same lights were also used -- the Jump setup was a common type, where the #2 skier buoy gate line also served as the MT gate line for the jump course, hence with the Ramp opposite #2 skier turn buoy and 10 meters back. Hence the entire approach from the 180 meter buoy past the ramp was well lit. As an aid to the jumpers, three buoys were placed approximately 9 meters left of the ramp centerline, at Distances of 55, 65 and 75 meters downcourse. These were clearly lit and helped the jumpers identify their position in the air relative to the water surface, which was otherwise virtually invisible with calm water. Results were quite impressive for both slalom and jumping -- with the winning Men's Slalom run of 5 at 10.25 meters, and winning Men's jump of 71.8 meters.
