Due to its ease of use and uncomplicated handling, the Flasher is the ideal light wind sail for the family crew. Sailing the Flasher is unproblematic even for the less experienced crew. Just attach the head and the tack, lead the sheet to the stern, put the spinnaker halyard through - and the sail can be sailed free-flying. The handling of the flasher is much easier and less complicated than sailing under spinnaker.
Since the Flasher can be sailed without spinnaker pole, topnant and downhaul, the Flasher is well suited as a light weather sail for the small crew. It is an independent sail and on many yachts the better alternative. The Flasher's greatest strength is clearly on half-wind courses from 60 to approx. 120 degrees wind angle. Here it is equal to the spinnaker. On more astern courses between 140 degrees and 'flat in front of the sheet', however, it gets into the cover of the mainsail if it is not unfurled. For this reason, and because the flasher has only about 85-90% of the area of a spinnaker, the spinnaker remains the faster sail on all pure downwind courses, since downwind the projected area is primarily responsible for the efficiency of a sail.
Head-Radial-Flasher The head-radial flasher is the standard flasher. The head tracks are cut radially, while the other tracks of the sail are made of horizontal tracks. The Head-Radial Flasher is designed for courses with a wind angle of approx. 85 - 150 degrees. For courses between approx. 150 - 180 degrees wind incidence a spinnaker pole is not absolutely necessary, but it is recommended.
Since the flasher, like all headsails, gets caught in the wind cover of the mainsail on courses 'flat before the sheet', a boomed-out flasher allows for a larger projected area and thus more propulsion. The head-radial flasher is the most economical way to sail flasher. It is particularly suitable for light to medium winds.
TRI-RADIAL-FLASHER The Tri-Radial Flasher is the ideal all-round flasher. The cloth runs radially from all three corners to the horizontal center seam. This cut variant thus represents a good compromise between dimensional stability and production effort. Due to the radial web arrangement from the head and from the clews, the occurring forces are absorbed exactly in the direction of the stronger warp threads.
This load-oriented sail design thus allows the Flasher to sail higher on the wind and over a wider range of wind speeds. The only weak point of this design is the slight deformation of the slightly less loaded transverse sheets due to diagonal stretching. The Tri-Radial Flasher is designed for courses of approx. 70 - 150 degrees wind angle. For courses between approx. 150 - 180 degrees of wind incidence, a spinnaker pole is not absolutely necessary, but it is recommended. Since the flasher, like all headsails, gets caught in the wind cover of the mainsail on courses 'flat before the sheet', a boomed out flasher allows a larger projected area and thus more propulsion. Due to its wide range of use, the Tri-Radial Flasher is the ideal all-round flasher on board.
