12m + 10m Dyneema line extensions allow you to adjust your line length for wave riding or tighter kite loops. The Navigator Control System comes with 22m of lines, with a split at 12m, which is wide enough for the bar to travel far enough 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. Shorter 8m + 2m line extensions are also available as accessories if you need 18m or 20m lines for wave riding or tighter kite loops.
