I fly a double headsail
rig when sailing downwind on my catamaran. It gives me nearly the same sail area forward as a
spinnaker, but with a lot less worries. One genoa to port and another genoa to starboard gets the job done nicely. I actually use two
spinnaker poles for the double headsail
rig. If the wind comes up, I roll in one of the headsails.
The last time I flew my
spinnaker solo, I ran over it. So now it's a double headsail
rig for me. I go just as fast without any worries.
