Description The Selden Kappa section was specifically designed for the 420 Class and continues to be the ideal section for the boat for the following reasons: Lightest weight mast. Performs like a stiff mast with correct spreader and chock settings. Will de-power with rig controls (the only DYNAMIC 420 mast on the market) . Reduced drag due to small section size. The Kappa mast has been the most successful 420 mast ever, winning more National, European and World titles than any other mast section.
