Rolly Tasker Asymmetrical Spinnakers are easy to use and optimise sailing performance in light winds on courses from 75 to 160 degrees. They
combine the characteristics of a reaching genoa with a spinnaker and therefore might fill a gap in your sail inventory. The typical characteristic
is a longer luff than the leech. The Tack will be fixed at the bow, anchor roller or bow sprite and is thereby flown without a spinnaker pole:
hence much easier to handle than a symmetrical spinnaker. For this reason they are widely used on cruising boats, though they are also an important
sail in a racer’s wardrobe to maximise reaching performance. When combined with a spinnaker sock the asymmetrical spinnaker becomes a sail that can
be used by single or short-handed crews under all conditions.
These are a full radial cut Asymmetrical Spinnakers ideally suited to the cruiser looking for durability, great value and all-round
performance. They come in 2 different colour options. In blue and white cloth with a central red star or in solid blue cloth. Both colours come complete with a large spinnaker bag for convenience.

Our one-off design asymmetrical spinnakers use a multi-panel tri-radial design, allowing for more precise alignment of loads, while the
increased number of panels enables the use of three dimensional shaping, creating the optimum flying shape with reduced seam loads. At
the corners of the sail we use fanned radial patches, which minimise weight,and increase strength. Naturally, they come standard with
stainless steel rings, large sail bags and your choice of colours and designs. We can supply your new spinnaker in a comprehensive range
of exciting colours and designs –

With a luff that is longer than the leech, the asymmetrical spinnaker is designed to sail with the apparent wind on the beam of the boat
rather than from directly behind, as is the case with a symmetrical spinnaker.
With a round entry, the maximum beam being forward of the midpoint and a flatter exit, the Asymmetrical Spinnaker directs the power forward
instead of sideways – hence creating boat speed rather than heeling.
At Rolly Tasker Sails we design your asymmetrical spinnaker according to the characteristics of your boat and the conditions under which it
sails. A very fast racer uses a rather flat sail with smaller shoulders for high speed and tight apparent wind angels. A cruiser, or for a
boat that doesn’t build that much apparent wind, would use a fuller sail with larger shoulders and wider mid girth, which in turn is more
forgiving, allowing the luff to curl quite a bit before collapsing.
In addition to taking into account your halyard exit to deck and J measurements, our Asymmetrical Spinnakers are designed around a measurement
of sail midgirth as a % of footgirth and typically range from around 70% for high speed to 90% for ultimate cruising.
