F18 Mainsail - Kangaroo Sails

The F18 mainsail from Kangaroo Sails is developed for Formula 18 catamarans and designed for both light and heavy crews. The designs are developed in-house, and Sven Lindstädt and his sailmaking team keep refining them – for racing and leisure sailors alike.

Features

• Easy to set up and trim
• Luff rope designed so that even single-handed sailors can hoist the mainsail effortlessly
• No tools needed to tension the battens
• Large windows for a good view to leeward (window option)

Sail cuts

• Beach – for leisure sailors: radial cut from the head and clew with 4 panels from the head, 10 from the clew and 1 panel along the luff. Flat, horizontal reinforcements, batten pockets in white Dacron; window film in the lower panels and a multi-colour layout possible.
• Hightech / Decksweeper – for racing sailors: radial cut with 6 panels from the head, 11 from the clew and 1 along the luff. The extra panels align the cloth better with the loads in the sail and give a better profile. Reinforcements cut flat and fully bonded, batten pockets in the same cloth as the sail; window and multi-colour layout possible. 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.

Sailcloth

• Mylar (smoke, blue, white, green, red): built like Pentex, with polyester fibres.
