North 5-A+ (Proctor) Lightning Jib
2015 Worlds Champion!
The 5A+ jib may be the "winningest" jib design in ILCA history. It's designed with plenty of power for lighter conditions but can still be flattened quickly for lighter teams and heavier air.
The 5A+ can be trimmed up to 5" inside the tip of the spreader for short periods of time but prefers to be trimmed 2-3” inside the spreader tip when you are “in the groove”.
The 5A+ jib is most successful with the M5 tuning system.
