Panelled Sails

Panelled Sails

As an alternative to the 4T FORTE™, M3™ and Vektor2™ continuous yarn options and VantageOne™ glued membranes, OneSails offers more traditional woven cross-cut and tri-radial panelled sails.

Woven cloth - the underrated sail material.

Even today, fabrics are still very popular. That's right, because fabrics are made without glue and without film. They are robust, durable and inexpensive. Sails in CrossCut are also the most cost-effective to manufacture.

Many will know, a fabric consists of long warp and short weft threads, which are interwoven at 90 ° angle. So that diagonal loads can be absorbed, as they occur, for example, in the sheet area of ​​a Genoa 1, the cloth manufacturers have come up with some ideas. For example, the polyester fibers are shrunk by heat after weaving. The fabric becomes more compact and gains in diagonal stability.
In heavily stretched sails, where the luff is a multiple of the lower leg length (called the high aspect ratio in English), the load is mainly parallel to the leech. These sails require a stronger weft (English "strong ll") to absorb these high forces. Typical high aspect sails include the Genoa 3 and sleek mainsails.

Suitable cuts
Depending on the aspect ratio and equipment, we recommend the CrossCut unlimited to 35 square meters. For larger sails, the radial cut has its advantages in terms of dimensional stability, service life and lower weight.

We use the following fabrics from Dimension Polyant for CrossCut: All Purpose (AP) and Stong Fill (SF) for high mileage and C Breeze (CB) for less than 750 miles per year. Suitable for: all sailors who are looking for uncomplicated and durable sails with high profile life.

The requirement for a fabric for the radial cut is different from the orientation of the webs along the load lines as compared to a crosscut.

Until recently, the fabrics were not advantageous for this web assembly due to the crimping of the warp crimp. The loads occurring in the sail initially pulled the yarns straight before they were caught. A new special weave creates fabrics that allow very stable sails without initial stretch.

This fabric is offered under the name Pro Radial. It is suitable for all sails except gennaker and spinnaker and achieves a very long service life.

Hybrid fabrics in which polyester fibers are interwoven with polyethylene fibers have the longest life among sail materials. Hybrid fabrics can not shrink evenly, for an initial diagonal stability, the yarns are mechanically roughened before weaving. In use, the achieved diagonal stability fades very quickly. We therefore recommend hybrid fabrics exclusively for radial cutting. The special weave of HydraNet Radial has been developed for this application.

Laminates - the right material for cruising sailors?

Laminates are good fabrics for rolling sails, the structural yarns are encapsulated between two scrims. These scrims are mostly made from Mylar. For the cruising sails, the films are provided with a so-called taffeta fabric from the outside for a longer service life. The external taffeta fabric works as a shield and offers a certain abrasion protection.

Unfortunately in all kind of laminates, the bond strength of the adhesive diminishes in use. In addition, the Mylar crystallizes. As a result, the laminate parts separate and the brittle film cuts the structural yarn fibers. In addition, there is an increased susceptibility to the formation of mildew.

The way the laminate is built makes it heavier compared to woven fabrics. The structural yarns can be made from different fibers. For cruising sails polyester or polyethylene make the most sense and the lifespan of these two variants is very different.

Suitable for: all sailors looking for sails with a medium-long service life or if you are unfamiliar with a membrane sail but still want a high mileage performance with a longer service life.

The cross cut or horizontal panels is the way to build simple and robust sails. However, loads outside the yarn directions of the fabric can not be absorbed. Therefore, the quality of the cloth used is crucial for the life of the sail.

The material:
OneSails uses two types of Dacron fabrics from Dimension Polyant for the production of CrossCut sails: Dacron HQ for a mileage of more than 750 miles per year and Dacron standard for less. In any case, it is important to have a premium quality weaving for a maximum high diagonal stability.
Some cloth manufacturers offer special laminates for the CrossCut. We do not process these laminates. Because our membrane technologies offer the advantages of higher profile stability, lower weight and equal lifetime.

Suitable for: low performing, long lasting budget sails.

The radial cut makes possible to produce sails that are lighter and more dimensionally stable than Cross Cut ones. In the radial panels, the yarns and the seams are oriented along the stressing forces lines of the the sail. The number of yarns must be chosen exactly to the prevailing forces - in general, the more yarns the better. Only this way, this cut guarantees a good shape holding and proper durability over time.

The material:
OneSails recommends fabric for the production of triradial sails, which have been specially developed for this cut. HydraNet Radial has been on the market for 20 years and has more than proven itself for high mileage sailors. It is the first choice for circumnavigators and those who expect the maximum life of their sails. Alternatively, we process ProRadial. It has a similar special weave and is intended for a mileage of more than 1000 miles a year.

Suitable for: Sailors looking for a good compromise of long lasting and shape holding.

Bei lastorientiert gefertigten Segeln folgen die Fasern konsequent der im Segel auftretenden Kräfteverteilung. Die Fasern werden für jedes Segel individuell gelegt und laminiert. Ein solcher Fadenverlauf kann auch dynamische Belastungen abseits der statischen Lastlinien meistern.

Im Laufe der Entwicklung neuer Fertigungstechniken für HighTech-Segel haben sich zwei grundsätzlich unterschiedliche Philosophien entwickelt. Die eine wird mit durchgehenden Fasern angefertigt während die andere aus einzelnen Bahnen mit unterbrochenen Fasern hergestellt wird. Für eine maximale Lebensdauer und geringes Gewicht setzen wir auf die modernen OneSails Technologien 4T FORTE™, VantageOne™ Filmless und Vektor 2™. Segel in OneSails Membran-Technologien sind geeignet für alle Am Wind Segel die in guter bis bester Form viele Meilen hinter sich lassen können.
