Nacra F18 Mainsail - Kangaroo Sails

The Nacra F18 mainsail from Kangaroo Sails is available for Formula 18 racing as well as leisure sailing. The Hightech cut brings more panels and a better profile, the Beach cut is the choice for relaxed sailing, and there is also a Decksweeper cut. The sail can be supplied measured on request.

Cuts at a glance

• Beach cut for leisure sailing: panels radiate from the head and clew – 4 from the head, 10 from the clew, plus 1 panel along the luff. Reinforcements are flat and horizontal, and the batten pockets are made of white Dacron.
• Hightech cut for racing: more panels so the cloth follows the loads better and the profile can be shaped more finely – 6 from the head, 11 from the clew, 1 along the luff. Reinforcements cut flat and fully bonded; batten pockets made from the sailcloth itself.
• Decksweeper cut: additional cut option. 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.

Options

• Window: lower panels in window film (possible with Beach and Hightech)
• Multi-colour layout possible
• Battens: none, with battens, or battens for the Decksweeper (DS)
• Qbond: yes or no
• Measurement: optional

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.
