CRUISING MAINSAILS
Titanium Douible-Taffeta
A continuous carbon load-path membrane wrapped in protective taffeta — light, low-stretch, and built to hold its shape season after season, without the bulk of heavy multi-ply Dacron.
Why a Titanium Double-Taffeta cruising main?
For cruising boats, a Double-Taffeta Titanium mainsail is a smart alternative to heavy, multi-ply Dacron or radially-paneled laminate sails. Continuous carbon load-path yarns are fused between two layers of shaped film, and the outer surfaces are covered with a finely woven polyester taffeta — a five-layer sandwich that keeps the sail light and low-stretch while standing up to years of real-world cruising use.
Holds Its Shape
Corner-to-corner carbon
Unbroken carbon yarns run from corner to corner, so load travels through the fiber, not the seams. The sail keeps its designed shape in puffs and lulls and resists the stretch that makes older mains bag out.
Taffeta-Tough
Built for cruising miles
A finely woven polyester taffeta laminated to both sides shields the film from chafe, flaking, and UV. It’s the durability layer that turns a high-performance membrane into a true long-term cruising sail.
Light & Easy
15–30% lighter, more flexible
Load-path yarns are laid dry, without glue, making the finished sail 15–30% more durable while staying lighter and more flexible. That means easier hoists, cleaner flaking or furling, and less weight aloft.
The five-layer Titanium double-taffeta membrane: taffeta, film, continuous carbon load-path yarns, film, taffeta.
Titanium® sails are made with a grid of continuous carbon load-path yarns running unbroken between the three corners of the sail; those yarns are laminated between two layers of 3D-shaped film. In the Titanium construction process the yarns are laid dry — without glue — to reduce weight and to keep the carbon from becoming brittle. A copolymer coating on the inside of the film holds the yarns and films in place until the final lamination is complete.
The five layers — taffeta, film, load-path yarns, second film layer, taffeta — are dropped into a variable-geometry thermo form, where the sail is heated and UV-bonded under vacuum pressure into a one-piece finished membrane.
Laying the yarns dry, without glue, makes the sail lighter (by 15–30%), more flexible, and more durable — which means happier foredeck crews and owners who aren’t replacing misshapen, broken-down sails as often.
Yes, there are seams in a Titanium sail, but they exist only to shape the film layers. Unlike most high-tech sails, in which structural yarns run only the width of an individual panel, a Titanium sail’s continuous yarns eliminate seam loads, load-induced distortion, wrinkles, and seam failure. The result is a smooth, wrinkle-free sail.
Extra Durability With Taffeta
While very strong on its own, a Double-Taffeta Titanium sail is made even more durable with a finely woven polyester taffeta laminated to both sides. The taffeta adds no structural strength, but it protects the film from abrasion — a major benefit for cruising sailors. Taffeta is available in white or grey.

FAQs
Is a membrane mainsail durable enough for cruising?
Yes. The taffeta layers laminated to both sides shield the film from the chafe and handling a cruising sail sees — flaking, lazy jacks, spreaders, and UV — while the continuous carbon yarns hold the sail’s shape far longer than woven Dacron, which stretches as it ages. Treated normally, a Titanium double-taffeta main is a long-term cruising sail, not a one-season race sail.
Will it work with in-mast or in-boom furling?
Yes — we build Titanium mains for powerhead, full-batten, and furling rigs. For in-mast furling we keep the section flat and use vertical battens (or none) so the sail rolls cleanly; for in-boom we match the luff curve and batten layout to your boom. Because the sail keeps its designed shape instead of bagging out, it resists the stretch that causes furling mains to jam.
Why taffeta instead of an exposed film or Lite Skin finish?
Taffeta is a finely woven polyester sacrificial layer. It adds no structural strength, but it dramatically improves abrasion and UV resistance — exactly what a cruising sail needs. Lighter exposed-film or Lite Skin finishes shine in racing where every gram counts; for cruising, the small weight penalty of taffeta buys years of extra service life.
How is this different from a Dacron or radial laminate main?
Woven Dacron and panelled laminate sails carry load across their seams, so they stretch and distort as they age. A Titanium main carries load on unbroken corner-to-corner yarns — the seams only shape the film — so there’s no seam stretch and the sail stays flat and efficient for far longer.
White or grey taffeta — does it matter?
It’s mostly aesthetic; both protect the membrane equally. Grey hides dirt and has a stealthier look, while white is the classic cruising appearance. Your local loft can show you samples alongside your existing inventory.
