12m + 10m Dyneema SK99 line extensions enable you to customize your line length for wave riding or tighter kiteloops. The Navigator Control System is supplied with 22m Lines, with a split at 12m, which is far enough for the bar to travel to completely depower our largest kite when you flag out. Remove the standard 10m top section of line and 12m lines are ideal for schools to teach with and for foil racing. Shorter 8m + 2m line extensions are also available as an accessory for those wanting 18m or 20m lines for wave riding or tighter kiteloops.
