I use a furler. So I really only use jib/spinnaker halyards for is to raise my jib cover. I want to pursue using a asymetrical spinnaker at some point, but I must confess I don't know which halyard is which? Need a clue. Pic supplied.
Thanks in advance
Assuming you have the CDI furler with its integrated halyard, the lower jib furler is not used. I just changed to a Harken furler that uses the jib halyard.
The sheave above forestay attachment is for the spinnaker.
The sheave below forestay attachment is for the jib/genoa.
Attach the asymmetrical to the bow (I started with a simple 1-inch pulpit eye —
Pulpit Eye for 1" Tubing) with sheets leading to the stern pulpit block attachment points.
It is simple enough to launch the asymmetrical with no other equipment but need to have two people – one on the tiller and one of the foredeck.
Using a sock/sleeve is the next level of simplicity for launching and dousing but still works best with two people. The sock/sleeve requires someplace on the mast to fasten the sock hoisting/dousing continuous line. If you are a serious racer, the raised sock does add a bit to wind resistance at the top of the mast.
If you want to use a top-down asymmetrical furler, the spinnaker sheave needs to be raised about a foot plus a bowsprit will need to be added to increase the separation of the jib/genoa and the spinnaker and the bow pulpit.
