North Sails Square Top Racing Mainsail NPC RADIAN White


High Performance Profile

Square-Top-Großsegel sind unsere fortschrittlichsten Großsegel und dominieren die Grand-Prix-Rennen weltweit. Das quadratische Top-Profil sorgt für hocheffizienten Twist, reduziert die turbulente Strömung im Masttop und optimiert die Verteilung der Segelfläche.

Die Designer von North stimmen die Profiltiefe und die Breite des Kopfbretts präzise aufeinander ab. Gleichzeitig fließen das Biegeverhalten des Mastes und die erwarteten Segelbindungen in das Design mit ein. Alle Segelelemente greifen ineinander, einschließlich des Membranmoduls, der Lattensteifigkeit und der Lattenkonfiguration. Das Segel ist damit insgesamt effizienter und hat einen höheren Wirkungsgrad.

Patented NPC RADIAN warp-oriented sailcloth is a unique non-laminated polyester material suitable for radial panel construction. Uncrimped warp yarns are interwoven with specially shaped fill yarns, allowing a more sophisticated radial panel construction than a traditional cross-cut layout. With NPC RADIAN, sailors enjoy lower stretch radial performance without films and glues.
NPL SPORT is woven by North Sails, and it’s the market’s highest performance 2D laminate race sailcloth. A proprietary polyester resin system resists heat, water, and UV at a level unmatched by any string sail. Sails cut from NPL are significantly stronger, lower stretch, and lighter than competitor brands.
3Di ENDURANCE is the most rugged high-performance sail technology. These sails are around the world tested for longevity and reliability. Many 3Di Endurance sails have logged the equivalent of more than two circumnavigations and are still in service. If you’re buying sails for adventure racing or bluewater cruising, choose Endurance.
3Di RAW is the sail technology choice of champions. These high-performance race sails are the lightest weight, lowest stretch, and most highly engineered sails on the planet. If you're buying sails exclusively for racing, go RAW.
