Buy a Spinnaker

The spinnaker – or Spi for short – is a particularly large, deep profiled foresail made of light cloth, which is used down wind and on a broad reach course to enlarge the sail area. In principle, all sails that are raised before the forestay can be called spinnakers. However, spinnakers have their own characteristics that not every sail fulfills. With a spinnaker in the narrower sense, the center width (the connection between half of the luff and half of the foot) is >75% of the foot. There are symmetrical and asymmetrical spinnakers.

Buy a gennaker

Asymmetrical spinnakers are also known as gennakers. Gennakers are either driven free-flying or on a furling system. We manufacture the gennakers ourselves according to your wishes. Whether runner (A1 / A2) for broad reach to downwind courses or reacher (G1 / G2) for half wind to broad reach courses or code zero. The Code Zero is another additional sail, which perfectly closes the gap between genoa and gennaker.
