Film-Film Membranes​

The most affordable continuous string technology

Vektor2™ represents the development of more than twenty years of experience in the construction of sails from a grid of continuous yarn on an adhesive film. This technology shares components and techniques used in the manufacturing of the M3™ sails and this permits the production of sails with an optimum cost / performance relationship for both cruising and racing sails.

Whereas in M3™ the structural grid, under pressure and temperature, is fused to the layers of Mylar that form the laminates, in Vektor2™ the grid is applied with reinforced fibre tape at high pressure to the film that constitutes the sail, in turn reinforced with the secondary grid at high pressure. Unlike how it is done for similar products in the market the reinforced tape of Vektor2™ is not made up of more yarns in line but of a single yarn.

This permits the complete utilization of the structural capacity of the fibres used in the grid with wide freedom of lay-out and complete control of the shape-holding in all the areas of the sail on the strength of the wide microdistribution and independence of each structural element. General parameters of the sail being equal (particularly the weight) a better structure is achieved for the efficient distribution of the loads.

The very latest innovation introduced by OneSails is the use of Endumax® as the fibre for the structural grid, that guarantees characteristics distinctly superior to the aramid fibres both in terms of durability and of performance. With greater stretch resistance and strength, together with a significantly reduced weight. As well as Endumax®, Vektor2™ sails are available with the structural grid in Carbon when maximum performance is required. Vektor2™ presents an optimum price / performance relationship and allows access to continuous yarn technology (a one piece sail) at competitive prices and conditions with respect to sails constructed with traditional panel technology.

Vektor2™ fiber layout

Small tapes driving one yarn

Outer Yarns

Inner Yarns

When bending, multi tapes structure keeps the same tension between outer and inner yarns.

Conventional fiber layout

One wide tape driving up to 5 yarns

Outer Yarns

Inner Yarns

When bending, single tape structure causes different tension between fibers, most of the load is on the outer yarns.


It is the most performing Vektor2™ style. Carbon is an high performance fiber sporting a very low weight / stretch ratio. It is suited to high performance racing yachts.


OneSails is one of the first sailmaker developing a process to build sails with continuous Endumax® UHMWPE (Ultra High Molecular Weight Polyethylene) yarns. Endumax® offers unbeatable performance and durability and is far more resistant to stretch, flexing and UV degradation than all other fibers in the exact environment in which sails operate. Endumax® is a high performance fiber and suited to performance racing and cruising yachts.

GRAN PRIX Base Scrim

Hi-performance scrim with a random array of non-woven filaments that provide considerable abrasion resistance at minimal weight gain, perfect for racing sails. Very light weight, durable and low stretch.

RACING Base Scrim

This scrim base perfect for furling code sails and small one design racers. Light weight and low stretch with zero water absorption.


Film and light taffeta on one side makes for a very robust sail with excellent longevity. Sails can be engineered so the taffeta is on the inside of the furling rotation allowing adhesive UV covers on the film side with furling genoa
