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. duringthe competition. List any malfunction of equipment. Give any further information which might affect the Tournament Council's assement of the homologation. Event went well once underway, especially the jumping, but preparation time was very minimal. Sponsoring group should have begun onsite setup at least 2 days earlier. Much rushing needed to set up and track down materials, such as towlines and video gear. Local jump ramp needed some work, especially cleaning and waxing. Some sidecurtain reinforcing was needed. Was waxed with IWSF-spec. paraffin-based wax with additives, and well-received by skiers. Surface was slightly 'scalloped' between the seams of the MasterCraft surface fiberglass panels. Ramp also needed winch cranks attached for solid anchoring. Jump ramp is in the way for slalom and tricks, and had to be moved out of the way during these events. When set back for jumping, it was checked with survey gear each time to be within 2cm of initial stakeout. Slalom centerline video had initial problems. Extender lens was not able to be used at full zoom and stay in focus. Eventually, a new camera was purchased, and provided a good, clear picture, although just large enough. The additional boat video for slalom scoring review was used for Friday's first round, and available via the pro cameraman's video out on Saturday, but not on Sunday, which had a film camera onboard. Surveying went well. A 2nd course was used for Round 1 slalom on Lake #2, because of available time. But both Lake #1 and #2 needed scaffolding for one of the slalom towers. Height was marginal on Lake #1, but any higher would have made it unsafe. Trick course was a brand-new trick course that was surveyed in vs. estimated. Some problems getting re-familiar with the video trick timing, but it mostly worked well, and there were no runs lost. Usually,, the Chief Judge acted as the trick time judge, with another Sr. judge assisting, and the homologator operating the computer. These potential records were recorded: [no slalom records] Jimmy Siemers, Round 3, 11070 trick points (AWSA Men1) Rhoni Barton, Round 2, 52.5m jump (AWSA Open plus Pan-am) Jesper Cassoe, Round 2, 67.1m jump (Danish Open, later raised in Round 3) Jason Seels, Round 2, 68.7m jump (EAME Men, superseded in Round 3 by Cassoe) Jesper Cassoe, Round 3, 70.7m jump (EAME Open Men) Curtis Sheers, Round 2, 68.3m jump (AA Open Men TIE) Emma Sheers, Round 3, 55.3m jump (World Record Women, exceeded 3 minutes later) Elena Milakova, Round 3, 56.6m jump (World Record Women) Freddy Krueger, Round 3, 71.0m jump (World Record Men) Of note is an unofficial 'record' for the sum of 3 jumps in one session by Jesper Cassoe in Round 3. This was a total of 688 feet or 209.7 meters.
