Driver

From Jump Letter Chart an official letter is produced, based upon skier weight and distance, the skier may accept this letter or select a letter three higher or lower. If the driver and Boat Judge conclude the letter is not correct and must be changed due to unacceptable speed, they must inform the skier of any change to the letter. Reference: Printed jump letter chart or system select from NEW JUMPER menu.

RPM Adjust Driver Adjust total boat RPM to compensate for each skier pull characteristic, wind and current. An increased ‘RPM adjust’ speeds up boat times in both segments.

S2% Driver Adjusts boat speed and times in second segment only. S2% is only effective when the jump switch is properly activated by skiers. Reference: initial setting from chart.

S2 RTB Driver Same as S2% when "Return to Baseline" is selected.

S2Fine Driver A direct RPM adjustment for the second segment only. Is present for every pass. Normally used only when Fast Second Segment is NOT selected.Reference: 0 RPM.

CT Driver Maximum allowed time during counter cut that RPM is added while jump switch is closed. Adjust to release skier and prevent boat over speed. References: normal 190 head wind 210 tail wind 170 skier ¾ cut 160
