OneSails delivers the next generation of high-performance racing sails, engineered for elite competition in Grand Prix, offshore, and club circuits. By integrating patented technologies like 4T FORTE™, Vektor2™, and Vantage One™, we provide owners with an unmatched edge in shape retention and durability. Proven by World, European, and National Championship victories, our racing inventories are custom-designed for the world’s most competitive one-design fleets and major rating systems including IRC and ORC.
Our racing range spans from high-performance woven cross-cut and tri-radial paneled sails to our flagship custom membranes, including Vektor2™ and the glue-free 4T FORTE™. By utilizing exclusive continuous fiber paths, we engineer sails with superior weight-to-strength ratios and unmatched shape stability compared to traditional laminates.
Whether paneled or membrane, every OneSails product is bespoke—custom-tailored to your boat’s specific rig and racing requirements using premium components to ensure maximum structural integrity over time.
Naked is the ultimate development of 4T FORTE™ composite technology, offering the highest loads/weight ratio per square metre. Specifically engineered for Grand Prix racing and competition at the highest level, 4T FORTE™ Naked ensures an excellent ratio of light weight and shape holding when compared to similar products available elsewhere.
4T FORTE™ composite sails incorporate the latest high modulus fibres but without mylar films and adhesives that characterise laminate constructions. Using a multi micro layered structure, the elements of the membrane are fused together resulting in a stable, stretch resistant and durable sail. By eliminating mylar films and adhesives, these sails are significantly lighter than the laminate alternatives.
Vektor2™ is the culmination of more than 20 years of development in the construction of sails incorporating continuous yarns.The continuous fibre grid is comprised of reinforced fibre tapes applied under high pressure to the film that constitutes the sail. Unlike similar products in the market, the unique tapes used in Vektor2™ maximize the structural capability of the fibres without restricting the fibre layout which in turn means excellent shape holding in all areas of the sail. Vektor2™ is available with several different fibre styles and allows access to continuous yarn technology (a one piece sail) at competitive prices when compared to traditional panelled sails.
Vantage One™ membranes feature complex arrays of curved fibres that distribute loads evenly across the sail reducing localised distortion and improving overall shape retention. The sails are laminated in sections before being cut, shaped, and joined into the final membrane. Although the fibres are discontinuous across the seams, the fibres are arranged in a way that ensures continuity of load distribution. The stringent lamination and shaping process results in efficient, easy to trim, durable sails with precise shaping and minimal shrinkage or distortion.
Tri-radial construction creates a more sophisticated means of distributing the loads in a sail than can be achieved with a cross-cut sail. Higher tech woven fabrics including Dyneema & Polyester hybrids such as Hydranet together with a range of dedicated laminates will offer better shape holding and hence improved performance and handling than cross-cut alternatives.
OneSails woven cross-cut sails are built using only the very best quality premium Dacrons. All Dacrons are not created equal. OneSails are particularly stringent when it comes to cloth selection in order to ensure that each piece of cloth is perfectly suited to its intended end use. Carefully chosen fabrics with tightly woven high tenacity yarns and built in UV inhibitors combine to offer sails with the best performance on small to medium sized boats where Dacron is the preferred or only choice.
Traditional racing sails rely on glues and Mylar films that are prone to structural „creep” and delamination. 4T FORTE™ utilizes a patented, glue-free fusion process and continuous fiber paths. This eliminates the primary causes of shape loss, ensuring your sail maintains its designed aerodynamic profile for significantly more racing hours than any standard laminate.
Our designers utilize proprietary Fluid-Structure Interaction (FSI) software to simulate real-world loads and aero-elasticity. This allows us to optimize the „Performance-to-Rating” ratio, ensuring your inventory is perfectly tuned to your boat’s specific rig and handicap requirements for 2026.
On the contrary, it enhances it. By removing heavy glues and resins, 4T FORTE™ is up to 25% lighter than traditional membranes. This weight saving, combined with the inherent stiffness of the composite, delivers a faster, more responsive sail. With OneSails, elite performance and environmental responsibility (via our 2026 Trade-In program) are no longer mutually exclusive.
Your choice depends on your performance priorities. 4T FORTE™ is our flagship Mylar-free composite, fused without glues to provide the ultimate in shape retention and weight reduction for Grand Prix and offshore circuits. Vektor2™ utilizes a high-modulus continuous fiber grid on a technical film base, offering an elite-performance, cost-effective solution for competitive regattas and one-design fleets.
Every membrane sail undergoes a full FSI optimisation. All of our lofts worldwide have access to a huge shared database updated in real time, containing thousands of sail designs from the World Champion Optimist mainsail to the biggest one-piece maxi yacht mainsail ever built. This includes construction details, which are specified to the highest standards on the market. FSI, Fluid-Structure Interaction, is the step beyond aerodynamic analysis (CFD), allowing real-life simulations where all the factors affecting sail shape are taken into account, like material deformation, rig interaction, laminar and turbulent airflow, sails backwinding, etc.
The use of such hugely powerful design tools ensures the designs are right, first time…
For over 15 years the OneSails design team have developed exclusive technologies to make one-piece continuous thread sails a reality for cruising and racing boats.
Features like weight, shape control and deformation resistance means better performance compared to traditional panelled sails.
Sails are designed and manufactured to the very highest standards from carefully selected components to ensure the very highest quality and durability. 4T FORTE™ membranes are exclusively made in Italy. All the assembly process is completely made in a unique factory ensuring the meeting of all the required standards.
The best sail shapes are the result of continuous analysis and experience. OneSails is at the forefront of the sailmaking industry, continually investing in research and development to ensure that the very best sail shapes are available. The success of this approach is confirmed by the vast array of racing trophies OneSails clients have won, competing at National, International and World Championship level.
A core activity for every OneSails Loft is providing first class service, support and assistance. As part of our service commitment, each OneSails Loft has a team of experts on hand to ensure that we can deliver on our service pledge. In addition to a growing number of principle lofts, the OneSails Group has an extensive network of service centres strategically placed worldwide’s coast line.
