DESIGNED FOR SPEED — ENGINEERED TO LAST Speed. Durability. Versatility. At UK-Halsey Sailmakers, we have been dedicated for over two decades to improving and refining what are now the fastest and most durable sails on the market: Tape-Drive®. Depending upon design shape and materials specified, Tape-Drive can be the ultimate choice for racing, for cruising, and - for some sailors - both! Advances in design, construction and materials have made Tape-Drive increasingly versatile. Tape-Drive is a two-part construction process in which the structural strength of the sail and the skin that defines the sail's three-dimensional shape are discreet elements. In this unique process, Tape-Drive marries a grid of high strength, low stretch tapes - the structural strength - to a three-dimensionally shaped membrane - the "skin" - made up of broad- seamed cross-cut laminate panels. The grid carries the primary structural loads of the sail, while the skin produces aerodynamic lift. The tapes, with a breaking strength up to 1900 pounds, radi- ate across the sail with a heavier concentration at the computer predicted high load areas - the corners and the leech.

TAPE-DRIVE: LIGHTER & STRONGER Tape-Drive is the only high-tech construction method in which the materials can be varied to suit the specific use of the sail. Depending on the size of your boat and its sail requirements, we select the appropriate membrane material from a wide variety of custom designed lami- nates using scrims of carbon, aramid. Spectra®, Pentex®, or polyester yarns. • Provide shape to the sail • Prevent passage of air from the windward to the leeward side of the sail...

less expensive than the high modulus yarns. Laminates made with Pentex yarns have better performance than polyester yarns, but are only slightly less expensive than laminates made with much better performing aramid yarns. Pentex laminates are only used when one-design class rules do not allow aramid fibers. SPECTRA TAPE-DRIVE: THE ULTIMATE CRUISING SAIL Above: J/133 with a Spectra Tape-Drive main.

WHEN REPAIRS ARE LESS EXTEN- SIVE, THEY ARE LESS EXPENSIVE The Tape-Drive construction system creates a unique "Rip Stop" layout, which prevents accidental tears from becoming catastrophic failures.
