ZONDA | for Grand Prix races
The sail is specially made for a specific boat, taking into account all the subtleties of the racing rigging. This mainsail will be 100% custom made based on a meticulous design that is developed by the customer and our specialists. Non-standard luff fittings, halyard locks, luff optimized for sizing rules. State your requirements and we will find the best solution.
Types of cutting
Cross cut
An x-cut sail consists of a series of horizontal sashes, parallel to each other and perpendicular to the leech. This is a reliable and fairly cheap method of manufacturing; the sail is affordable and durable. In fact, the cross cut is the ancestor of sailing design and sails with this cut have a proven track record.
Cross cut sails are usually made from woven polyester fabric with weft threads that are stronger than warp threads. The canvas is oriented towards the direction of the load, resulting in a very strong sail.
Tri-optimal fit
Tri-optimal cut, also known as radial cut. The sail is sewn from radial pieces that are oriented towards the corners of the sail. This arrangement optimally distributes the forces that act on the sail and helps to maintain the correct sail shape. Pieces of fabric for radial cutting are laid out and stitched according to the load diagram, providing strength and stable sail shape.
Upwind sails with a trioptimal cut are usually made of "laminate" - a fabric made up of several layers. However, there are sails with a radial cut made of polyester fabric, for example, most nylon sails for full courses are tri-optimal cut.
EPEX
The unique and patented EPEX membrane technology is the flagship of Elvstrøm Sails. 100% custom design in which each power fiber is positioned according to the load diagram. Each sail is calculated by a special computer program according to individual preferences. This ensures absolutely optimal fiber distribution throughout the sail, resulting in exceptional shape stability and maximum recoil.
A wide range of materials and fibers are available to suit any need. All air between the layers and the power fibers that make up the sail is removed by vacuum and the entire canvas is “baked” into a single whole.
