8m + 2m Dyneema line extensions for those who want custom 18m or 20m lines for wave riding or tighter kite loops. The Navigator Control System comes with 22m lines, with a split at 12m, which is far enough that the bar is far enough away to fully depower our largest kite when you flag out. Remove the standard top line section of 10m and 12m lines are ideal for schools to teach with and foil races.
