Marathon/Performance Series 400
Superior shapeholding and UV resistance for 40 ft.+ cruisers

North Marathon and Performance Series 400 sails are a preferred choice for cruising boats from 40 feet to Superyachts, delivering high performance and easy handling around the bay or around the world.

Made with Spectra or Dyneema laminates, equivalent products* that are nearly perfect for high-performance cruising sails because of their low weight, high strength and extremely high stretch resistance. Perhaps more importantly for the offshore sailor, Spectra or Dyneema also delivers unequaled resistance to wear from creasing and flex plus excellent UV resistance. Radial construction also contributes to superior shapeholding.

Marathon Series 400 sails are also available with North's Gatorback™ diagonal X-yarn reinforcement for additional shapeholding. The result is race-level sail performance suitable for long life at sea.

Performance Series 400 sails are specifically optimized for performance cruising, class racing, handicap rules or rating rules.

Product Highlights
  • High performance laminated Spectra or Dyneema fabrics
