As an alternative to the 4T FORTE™, M3™ and Vektor2™ continuous yarn options, OneSails offer VantageOne™ glued membranes that are built using industry standard, calendered, lamination techniques, as well as more traditional woven cross-cut and tri-radial panelled sails.
Most sailmakers can offer custom membrane type sails that feature discontinuous fibres. What makes the VantageOne membranes, offered by OneSails, different is firstly the complexity of the fibre array and secondly the quality of the lamination process. The sails are laminated in sections before being cut, shaped, and joined into the final one-piece membrane. Advancements in lamination and seaming techniques have effectively eliminated seam failures and delamination.
The overall result of this stringent lamination and shaping process is durable sails with more precise shapes and minimal shrinkage or distortion. The custom fibre array features more fibres in the 'off threadline' directions than other sail brands that rely on a more simplistic 'loadpath' model. This creates a more efficient structure that is easier to trim due to a wider effective wind range with increased durability and better shape retention.
These membranes are available in two distinct styles, 'aligned' and 'non-aligned'. The aligned membranes feature complex arrays of curved fibres that distribute loads evenly across the sail reducing localised distortion and improving shape retention both across the sail's wind range and across its useful life. Although the fibres are discontinuous across the seams, the fibres are fully aligned, ensuring continuity of load distribution.
VantageOne™ membranes are available with a variety of fibre arrays including Twaron (Kevlar), Technora and Carbon with Polyester also being available as a budget option for non aligned membranes for boats of up to around 30 feet. The addition of a single or double taffeta backing makes them more durable and more suitable for cruising than their racing counterparts without the expense of the more rigorously engineered alternatives.
Although the more simplistic non-aligned membranes are laminated and constructed in the same way, they have a less sophisticated fibre array with fibre paths that aren't necessarily aligned across the seams. The non-aligned styles do still however represent a better engineering solution to load distribution than more traditional tri-radial sails and should be considered on boats of less than 40 feet or so when a custom product is desired without the expense of the higher tech 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. Tightly woven high tenacity yarns with built in UV inhibitors combine to offer the most durable sails on small to medium sized boats at the most affordable price.
Tri-radial constructions create a more sophisticated means of distributing the loads in a sail than can be achieved with a cross-cut sail. Higher tech fabrics including Dyneema reinforced Hydranet and a range of dedicated cruise laminates will offer better shape holding and hence improved performance and handling than the cross-cut alternatives.
