Each design process starts with the measurement of the rig. The sail designers at Elvstrøm Sails then use the rig data to create an exact, three-dimensional computer model. This means the sail plan can be perfectly matched to the geometry of the rig without even the slightest bit of sail surface. Special attention must be paid to spreader sweep and (wind-related) factors like mast bend and luff sag (backstay tension) so precise knowledge of the different types of boats is essential.
Our designers are all active sailors, fully aware of the dynamic behaviour of modern rigs and with access to a database of 3,000 types of boats.
