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. Video jump measurement tests: Two grids were install for this tournament for two cameras. Computer system as per B.Corson specifications. To test the acuracy of the video setup we used a direct measure to points created on the water surface by a marker on the line end. Two lengths were tested ... 22.6m and 45.65m at a variety of radii from the ramp centreline. These marks tested both grod A and Grid B camera setups. On all test points the video system produced results with +/-50cm tolerance. The grid buoys were included in the standard jump course survey. The standard protractor meter system stands are a permanent facility at the sight. This system was not used for this but remained available. The slalom and Jump courses were survey (and approved ) during the week prior to the tournament. Standard three point survey reduction spreadsheets used to confirm courses. The site is a small lake with depths >20m along the slalom course. Hence accurate bottom anchored courses are not possible. The slalom course comprises a standard tensioned centre line floating course with PVC booms plus the following support lines. a) One longitudinal line down each turn buoy side. Boom ends clamp to this line to support longitude swing. b) One cross line (shore to shore) at each boom. The boom clamps to this line at the turn buoy to support latitude swing. c) One cross line as for the turn buoys at each set of entrance gate and pre-gate buoys. The gate booms clamp to these lines also at the turn buoy end. The space between the turn buoys and boat guide buoys is locked because of the measured fixings on the boom. This construction results in a very stable course in all weather conditions. Longitude and latitude adjustments can be made where required. I omitted to log the software version of the Perfectpass system on the boat. However the boat was a new Mastercraft Prostar just received in NZ under the care of Steve Cockeram. We had no problems with the system in all disciplines.
