The following section is where free form comments are added and attachments are made. HOMOLOGATOR'S REMARKS ***REMARKS*** ?Is there a 2002 version of this Dossier? For example this version doesn't mention 6.80m allowed out of water on the jump ramp. Only references 6.7 Jump ramp had a marking line across that ran from 6.60 to 6.80. Was waxed according to new IWSF specs. Jump ramp was a 'ski fly' length ramp with reduced floatation at the low end to produce the proper length. First elimination round of SL & JU was run as AWSA Class C because of excess rounds. Spectra Jump line was supplied; was not selected by any of the jumpers. Site is marginal on width for jumping at about 72m. Jump course was angled by about 7 degrees to the shoreline to create more effective width. Shoreline obstacles were also cleaned out & removed. But more work is needed in this area: recommend digging out a jump pass-fall zone at least 10m wider. Perfect Pass speed control worked generally well. ABT was used. Eric Horton of PP was there to manage the system. Minimal rerides esp. in slalom. Notable is no adverse comments back from skiers about boat or course or ramp. Other than possibly putting in a reverse direction jump course to guarantee headwinds. Time constraints plus favorable winds allowed using the 'normal' setup. With widely varying temperatures from cool 50's in the AM to sunny high 80's in the afternoon there was extra attention needed to buoy sizing so that they were neither too low early or too high & large later The jump test buoy was placed at about 65m downcourse vs. 60m to be in a more critical location. There were several jumps in excess of 65m with a top of 69.8m. Note that the coordinates given are vs. the survey axis. The jump ramp coordinates are: (5.992 33.986) and the jump course runs at -7.0 degrees to the survey axis. By survey the test buoy was (-64.50 -10.98) vs. the jump ramp centerline at (0 0) The ramp was set 'open' about 3.0 degrees to the course. Good anchoring (from 5 years back) stayed put. Presumably 'optional timing method' in the jumping checklist refers to the allowed faster 2nd segment times (used). Video jump was used; also video for slalom endgates; also SL video from the boat that included live transmission--when it was working. Thanks to Chris Parrish for supplying a handle checker to replace the nail and marks. Pro Tour had lost its handle checker in the off-season. SL centerline video supplied by the local site was very good as was the SL tower video. Thanks for this help. Several shortcomings by the sponsoring club (NOT the local site) vs. proper equipment for running a waterski tournament. Should be noted and corrected in the future. Ex: buoys; magnets; anchors; ramp height indicating tapes; handle checker; video gear; etc. All these were corrected at some expense of setup time. Fortunately there was a volunteer Asst. Homologator to help during most of the setup week and all of the event. Thank you Slade Cole and Jack. The Tour should give as much attention to the actual production of the waterskiing as it does to the land carnival.
