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. 7. Posting of Homologation Notice was overlooked 12.TNL was erected as a temporary structure and well within toleracnce. Correcting issues with previous homologation. In the case of TFR, the 41 degree line runs across the diagonal of the 2.5m squaretower and the judges, by sitting to the rear of the tower had their heads within the limits required by the rules. Height is good and sight is perfect. 16.Temporary structure was erected with judges and cameras about 4M above water. Jump system The Boettcher video measurement system was used. Though the survey xy co-ordinates of the 40 and 60M buoy were available, only check disatnces were available from the viseo system. 40M survey- 41.51, video- 41.6 60M survey- 59.08, video- 59.1 Both within 150mm tolerance for "L" homologation. Additional after - the - fact remarks by BDW:- Ramp setting for the nominal 1.8m height was outside the fore-shortened limit lines for this height on the ramp setting chart because the length was less than 6.6m, however the angle was almost perfect. It is considered there would be no discernible performance effect and if there was one, it would be negative. Furthermore the length was in compliance with the table at rule 13.02b. Survey data was checked in Dave Clark's spreadsheet, Emmanuel Lion's homologation program and a survey/cad program. The slalom pre-gate buoys were out of tolerance. While it is acknowledged that the rules require them to be in tolerance, performance is not effected positively by this error. Jump survey was problematic. There was an apparent error on the survey readings on the jump. The readings on the ramp centre gave a point that was 1.12m from the inside corner and 3.13m from the outside corner. The two points surveyed as the corners of the ramp were 4.25m apart whereas the directly measured width at the top of the ramp as shown in the dossier was 4.18m. The corners appeared to be surveyed correctly with respect to the rest of the course. Emmanuel's program showed a number of out of tolerance errors, the width of 210 and 180 were shown as out of tolerance, but this appeared to be due to the program adopting a tolerance of 150mm rather than the 500mm given in the rules. Emmanuel was contacted and a corrected version of his program was provided. 19ST was shown to be too narrow in agreement with both Dave's spreadsheet and the cad analysis. Emmanuel's program showed 'Ramp to 15ET' as out of tolerance at 15.158 and 'Ramp to 15MT' as in tolerance at 15.143 Dave's spreadsheet had '15CL - Rctr' out of tolerance at 15.158. As a check, all the data was deleted from the spreadsheet except 15ST, 15MT, ROHC and RIHC. It then gave '15CL - Rctr' as 15.143 agreeing with both Emmanuel's program and the cad analysis. It appears that Dave's spreadsheet does not strictly follow the rule which says "The basis of the jump course is the 15ST - 15MT line." but instead attempts some sort of least squares adjustment or a different basis. A further cad check then disclosed that the perpendicular distance from a line drawn through 15ET parallel to the 15ST-15MT line to the ramp centre is 15.158 This agrees with the figure given by Emmanuel's program for 'Ramp to 15ET'and inexplicably, with Dave's spreadsheet's '15CL - Rctr' with all the data inserted. Going back to first principals and returning to the rules in an effort to make sense of this, it is noted that there is no explicit statement in the rules as to the off line tolerance of 15ET and 15 EC from the 15ST - 15MT basis line. It is therefore submitted that the error, while lamentable, and a point for lessons, should not be cause for revocation of homologation.
