Headsails designed for maximum range and versatility.

Quantum's furling headsails represent the ultimate evolution of the standard in cruising sail design and construction, bringing an unmatched level of refinement and attention to detail to the workhorse of the cruising inventory. Durability, ease of handling, and performance are equally weighted design criteria along with maximum range and versatility in a reefable sail.

The shape of a sail is key to its performance. That's why all headsails are designed using Quantum's proprietary iQ Technology®, combining three dimensional shaping, computational fluid dynamics, and finite element analysis (FEA) to create custom shaping. Each sail is tailored on a sail by sail basis to expected usage and boat specific constraints.


Two construction options

Woven Polyester (Dacron)  Woven mainsails rely on the proven performance and durability of traditional woven polyester. They continue to be the most popular and affordable type of mainsail construction for small to medium size cruising boats. Woven mainsails provide excellent balance between performance and durability.

Fusion M® Composite Membrane  Fusion M® cruising mainsails utilize composite construction. They are engineered on a sail by sail basis as one-piece membranes with custom fiber mapping tailored to the sail's design purpose and expected usage. They can utilize a variety of fiber types. They provide lower stretch and greater strength, improving both intiial performance and long term shape retention without sacrificing durability and reliability.



All Quantum® cruising headsails are ruggedly built to take on the most ambitious sailing plans with wide seams, triple-throw stitching, extra layering, a unique batten pocket system, webbing and proper reinforcement throughout.
