FST – next generation string sails
Technical details
Producer: UK Sailmakers (UK)

FST Sails are the next generation of high performance membrane sails being produced by UK-Halsey. Previously they made string sails called UK-Ultra; however, the new product is so improved that they have named the result FST for “Fiber Sail Technology.” FST accurately describes the product and builds on the five years experience of producing the UK-Ultra membrane sails.
Membrane sails offer the best performance advantage due to their exceptionally low weight, high strength, and consistent, uniform shape. FST Sails are constructed of carbon and aramid fibers (either separately or together depending on specification and end use) laid down between Mylar film and laminated together to produce a homogeneous membrane that is light, durable and highly functional.
FST Sails are positioned at the top end of the Grand Prix and Racer/Cruiser markets. FST sails provide the best overall performance for invested money. From a technical perspective there are many advantages to using an FST sail.

•FST sails are produced using fully computerized CAD design and automated manufacturing.
•FST sails have very low – miniscule - crimp and no low-load elongation. Crimp is essentially the flex or expansion when the sail fills.
•FST sails have full reproducibility and adherence to mold design. They are consistently reproducible; if you order one and then replace it from the same design the sail will be exactly the same shape.
•FST sails have three-dimensional shape fully built into them. Design process and software produces the optimal 3-D shape for every purpose.
•FST uses Relax 2 sail simulation software for structural yarn analysis to ensure optimum production of sails.
