With a leech length different than its luff length, an asymmetrical spinnaker displays the best features of both a classic forward sail and a symmetrical spinnaker…with few of their drawbacks.
Because an asymmetrical clew flies higher than its tack, it can be set on the bow like a jib, or on the bowsprit, without requiring the use of a spinnaker pole, all the attendant hardware… and additional crew members to handle the beast.

Asymmetrical spinnakers are generally a little smaller (for the same boat) than their symmetrical cousins. They are also a little less suited to a dead run, since they tend to sit in the wind shadow of the main when running. Then again, because jibing is so much easier, a boat with an asymmetrical will go downwind as fast, and more comfortably by jibing 20 deg either side of a dead run…

Standard Asymmetric Spinnakers

Our asymmetrical standard spinnaker has a modern all-around tri-radial panel layout with medium draft. The cross section shape has a softly rounded entry, that straightens and flattens towards the leech – this draft shape makes the sail more tolerant, easier to trim, and minimizes heel when on a tight reach.

For maximum simplicity, you can even use it with a sock – maximum fun, minimum hassles when you have a reduced or inexperienced crew!

This is the ideal, multi-purpose sail for the skipper who does not want to deal with more than one spinnaker – optimized for wind angles in the range of 80 – 155
