Butterfly Mainsails

Custom Butterfly Mainsails: Handcrafted for Speed & Style

The Butterfly is a legendary scow that demands a sail as agile as its name. At Mad Sails, we combine championship-winning patterns with your personal style. Each Butterfly mainsail is handcrafted in our local loft using premium 4 oz high-tenacity woven polyester, engineered for superior color-fastness and shape retention in all wind conditions.

Design Your Own: The Ultimate Custom Experience

Want to stand out on the lake? Our Butterfly mains are available in two distinct styles:

• The Classic White: Clean, professional, and built from lightweight white woven sailcloth.

• The Full-Color Custom: Let your personality fly. Use our Butterfly Mainsail Design Tool to choose any color for any panel. Our colored sailcloth is selected for its high UV resistance and vibrant finish.

The Podium Series – Pro-Level Racing Cloth

For the competitive Butterfly racer, we offer a specialized HTP® plus racing main. This isn’t your standard Dacron. HTP® plus is engineered for low stretch performance. Its 1% bias stretch control means that once you tune your sail, the shape stays locked in.

What’s Included with Every Mad Butterfly Main:

• RBS Tapered Battens: For the perfect foil shape.
• Visibility Feature: Foot window placed for safely navigating a tight fleet.
• Class Insignia & Numbers: Professionally applied and Butterfly Class Association compliant.
• Complete Package: Includes tell-tales, a sail tie and a protective envelope-style sail bag. Mains made with race cloth come with a roll bag.
