420 Jib – K5 Model
Precision. Balance. Performance.
The new Zaoli K5 Jib represents the latest evolution in our 420 sail development.
Designed using our next-generation aerodynamic simulation software, which reproduces virtual wind tunnel conditions, the K5 introduces a new level of precision in shape control and pressure distribution.
Its semi-radial panel layout ensures a smoother load path and perfect shape stability under varying sheet tensions. The result is a jib that stays perfectly balanced across a wide wind range — from light to strong breeze — with minimal distortion and maximum efficiency.
On the water, the K5 feels remarkably easy to trim and more forgiving to different mast settings. It delivers higher pointing angles and improved acceleration out of tacks, giving crews more control and confidence in any condition.
Key Features
-
Virtual Wind Tunnel Design – digital fluid-dynamics simulations optimize pressure flow and twist for real-world performance.
-
Semi-Radial Cut – ensures uniform load distribution, maintaining shape stability in gusts and waves.
-
All-Round Performance – smooth power delivery and effortless trimming in all wind conditions.
-
Enhanced Pointing Ability – refined entry and exit angles increase upwind lift without sacrificing drive.
-
Stable & Forgiving – less sensitive to rig tension and easier to keep fast through changes in trim or sea state.
Every detail of the K5 has been refined for speed, simplicity, and control — qualities that define the modern 420 sailor.
