The asymmetrical spinnaker is mainly used by the cruising
and short handed sailing boat. It's advantage is the ability
to sail better at deeper downwind angles while not requiring
the use of labor intensive poles and multiple control lines
and topping lifts etc. The disadvantage vs a symmetrical spinnaker
is that it will not set well as deep but the advantages to
a cruising and short handed crew far outweigh this.

recommends an ATN dowsing sock with all these sails to ease
handling of the sail.
