The following section is where free form comments are added and attachments are made. HOMOLOGATOR'S REMARKS Notes:- Slalom course used one longitudinal line with 2.5m spreaders. Screw anchors were used to establish stability and accuracy to lateral movement. Course was accurately set using Theodolite and EDM. Skier turn buoys were accurately set with screw anchors during survey. Jump course was set in a similar manner but with 4.0 metre spreaders and screw anchors to prevent lateral movement. Slalom was not able to be R/C due to absence of end course video system. Second round of jump not able to be R/C due to movement of jump due to movement of Jump ramp caused by large wakes from Wakeboard boat. Jump reset during Jump event with insufficient time for full survey and testing. Second round for Male jump abandoned. Japanese three point X and Y co-ordinate Video system used without Video backup or review. In my opinion rules do not allow for this type of system. This system does not require backup Video (three would be required or an expensive video mixing system). As rules allow metering backup which could never be as accurate as this system Video backup appears to be overkill. When testing 60 and 40 metre test buoys System gave exactly the same distances as the Theodolite survey plus 2.1 m. Homologator recommends R/C for jump for Round 1 as the Muto system has been approved by Council.
