The 5.5 Speed sail is designed specifically to fit the stiff light weight carbon composite front tubes which are also option to the standard frame. The sail can be used with composite fiberglass front tubes as well, but the flatter luff curve was designed to fit the stiffer light weight carbon front tube upgrade to the standard frame.
The sail is constructed from a light weight scrim fabric at Ezzy Sails. The scrim fabric is closely woven polyester scrim and X ply laminated on both sides with clear film. The sail includes Dacron luff sleeves with Cordura reenforced openings and chafe points, cam lock tip tensioners, three position reflex tensioner, and leach strap.
The 5.5 Speed sail features a reduced luff curve. However, it can be tuned through a fairly wide range of foil shapes. The 5.5 Speed sail fits the standard frame as well as the stiff frame. It is likely the best option for folks seeking a cleaner, lighter foil for racing. Full battens can still be used.
The Speed is standard with carbon front tubes, an aluminum X tube, EVA coated Y tubes and boom with fiberglass tip wands.
Two cleats at the clew end of the Speed boom are standard. Options include an all carbon frame, a hybrid carbon and aluminum frame, or standard aluminum Y tube and boom set ups.
Folks who seek to jump or stunt with the 5.5 sail should use a re enforced X tube.
