Nacra Infusion Mainsail - Kangaroo Sails

The Nacra Infusion mainsail from Kangaroo Sails is available in three cuts. Racing sailors choose between Hightech and Decksweeper – both with more panels for a better profile – while leisure sailors opt for the Beach cut. The sail can be supplied measured on request, with cloth, window and battens chosen to match.

The cuts

• Beach (leisure): radial layout from head and clew – 4 head panels, 10 clew panels, 1 luff panel. Flat, horizontal reinforcements; batten pockets in white Dacron.
• Hightech (racing): radial layout with more panels – 6 head panels, 11 clew panels, 1 luff panel – so the cloth follows the loads more closely and the profile is cleaner. Flat, fully bonded reinforcements; batten pockets in the sailcloth.
• Decksweeper – also for racing sailors and built with the same features as the Hightech cut: 6 panels from the head, 11 from the clew, 1 along the luff, fully bonded reinforcements. On a Decksweeper the foot reaches down to just above the trampoline (usually with a curved boom): sail and trampoline act like an end plate, reducing the tip vortices along the foot for better pointing and speed upwind. Widely used in racing since the 2017 F18 Worlds.

Configuration

• Window yes or no – the lower panels are then made of window film (all cuts)
• Also available in several colours
• Battens: none, with battens, or for the Decksweeper (DS)
• Qbond: yes or no
• Measured: yes or no

Which cloth?

• Pentex – the laminate for racing and cruising sailors: a core of Pentex fibres sits between two Mylar films and gives the cloth high strength and shape stability at low weight. The three layers are bonded under pressure. Colours: black, smoke, white, silver.
• Mylar – built like Pentex, but with polyester fibres in the core. Colours: smoke, white, blue, green, red.
• Dacron – woven polyester sailcloth, valued for easy handling and long service life. Colour: white.
