What makes Fusion M® mainsails so great?

Superior Lamination

Quantum is the first composite membrane sail to be warrantied against de-lamination. Quantum's lamination process uses extreme heat and pressure to thermo-set the adhesives resulting in a cross-linked molecular structure with four to five times the strength of conventional thermo-molded processes—it's the key to producing superior membrane sails. Our two-step lamination procedure begins with vacuum bagging to lock fibers in place between film layers. Then infrared heat is applied with six-to-eight tons of pressure (12,000psi - 16,000psi) to thermo-set the adhesives. Films are coated with UV inhibitors to insure protection, longevity and performance.

Sail Shape

Sail shape is central to your sailing enjoyment. To achieve the optimal shape, Quantum's talented sail designers use a suite of the most sophisticated computational design tools in the industry. Our proprietary iQ Technology® combines three dimensional shaping, computational fluid dynamics, and finite element analysis (FEA) to create custom shaping, tailored on a sail by sail basis to expected usage and boat-specific constraints such as mast bend, displacement, and righting moment. Mainsail shape features a smooth, flat aerodynamic profile for optimum upwind performance, with an open trailing edge to reduce heeling and weather helm. The shape allows sailing into a higher range of wind conditions before reefing becomes necessary.


Producing a membrane sail shape to the exact specifications of the design process requires advanced sail making technology. Unlike single-step lamination and shaping methods used by other sail makers, Quantum's sail panels are completely cured before the shaping process begins. Fully-cured lamination eliminates the effects of shrinkage and guarantees repeatability. Quantum's Fusion M® sails have the best initial shape and the longest shape life of any sail built today, without sacrificing the durability and reliability that is the fundamental performance requirement of a good cruising sail.

Batten System

Fusion M® mainsails utilize fully integrated batten pockets. One full, and three mid-length battens are standard. More full-length battens can be added for additional structure and durability. Non full-length battens are 60% of the sail's girth measurement at the batten locations. Multi-layered pockets with backing plates are engineered for maximum durability. The pockets are typically leech loading with a specially designed batten end fittings for easy installation and removal, batten tensioning, and no "shake-out" security.


Custom, tapered battens improve sail shape and durability. The taper and stiffness are matched to the sail design to stabilize the sail shape helping keep the draft forward and the leech exit flat as the sail loads up. A soft taper blends smoothly into the fabric at the batten inboard ends, reducing hinging and hard spots at batten tips. Battens feature rugged "E" glass construction, with a machine-milled taper.

Custom Headboard

A super-strong custom aluminum headboard, reinforced with pressed stainless steel rings and webbing, or a special stainless headboard is made for larger boats. Roach profile, head angle, and attachment system are all factored into the headboard, which is designed on a sail-by-sail basis.

Reefs

Fusion M® mainsails have custom fiber mapping to address reef loads. The number of reefs and reef spacing is specified based on anticipated usage and boat characteristics. Spacing is not limited to the traditional 10-12.5% of luff length, but may be increased or decreased as appropriate to design criteria. Luff and clew reef hardware is custom designed to accommodate various reefing systems, including single line, separate line, simple tack hooks, or other configurations.

Luff Hardware

To ensure easy raising and lowering, and to eliminate wear and tear at the inboard end of full-length battens, various receptacles with universal joints and special slides are available. Your Quantum® consultant will discuss your options and confirm after on-board measurement.

Foot Shelf/Loose Foot

A section of fabric attached to the foot increases the depth and power in the lower third of the sail when the outhaul is eased. It is especially useful in light to moderate winds and when reaching or running.

Hand Finishing

The head, tack, clew, and reefs are hand finished using stainless steel rings, reinforced with webbing. The clew and each leech reef include a hand-sewn leech line cleat.

The first membrane sail for cruising sailors.

Quantum is the first sail maker to offer a complete range of composite sails featuring one-piece membrane construction, specifically designed for cruising sailors. They are made for discerning cruisers who are unwilling to compromise on quality and demand ultimate durability and performance. Compared to woven polyester sails, Fusion M® construction provides significantly better shape when new, and dramatically improved shape life over the long haul. Fusion M® mainsails can have two to three times the shape life of a standard woven sail. The result is a mainsail that is easier to trim, controls helm and heel, provides superior reefing, points higher, and is faster on every point of sail.   

 

Quantum's Fusion M® mainsails are developed using the most technically advanced design, lamination, and shaping methods in the industry—a proprietary and integrated process known as iQ Technology®. Fusion M®cruising mainsails are fast, easy to handle, efficient, and capable of taking you across the bay or around the world.

 

Fusion M® Membrane
Fusion M® mainsails are engineered as full-size membranes and designed with a fully-integrated, custom, fiber network that addresses sail loading equally in all directions rather than simply along primary load paths only. This fiber map is developed using highly sophisticated computational fluid dynamics (CFD) and finite element analysis (FEA), which recognizes the ever-changing nature of sail loads and the need for adaptability. The resulting fiber network is complex and very dense, creating a structural system that supports the entire sail because there is consistent stretch in all directions (referred to as "isotropic"). The Fusion M® isotropic fiber matrix prevents any one part of the sail from becoming overloaded or distorted. The net result is a sail shape that lasts longer and is easy to trim through a wide range of conditions because it changes evenly and uniformly.

 


Fusion M® cruising mainsails are available with different types of fiber, providing a range of options for different size boats and sailing requirements. Fibers are sandwiched between layers of film and rugged, woven polyester taffetas for ultimate durability.

to Break
  The measure of a fiber's ability to resist stretch. This indicates how well the fiber will perform in terms of holding sail shape. The higher the rating the less the fiber will stretch.

The fiber's initial breaking strength. A good measure of a fiber's ultimate tensile strength. The higher the rating the more load it takes to break the fiber.

A measure of strength lost due to bending, folding, or flogging. The fiber's ability to retain its strength after being folded back and forth over several cycles. The lower the rating the better the flex life.

Strength loss from exposure to the sun's UV rays. This is a measure of the effect of sunlight on the modulus (strength) of the fiber. The higher the rating the better the UV resistance.

A measure of the fiber's ability to resist shock loads; elastic stretch resistance.Analogous to the stiffness in a spring. Higher ratings mean more stretch and resistance to breakage.
