If you are going to use an assymetrical
spinnaker when sailing alone or when sailing with less experienced crew, or even if you do not have much experience yourself,
rig a quick release clew
shackle.
Basically in the clew
shackle trigger, you
rig a smaller diameter
line that you route back to the cockpit, and secure in a easy to reach location, that once pulled allows the clew
shackle to open..(joking in my country we call that the "hand brake")...
Then in the event of a broach, a large puff or simply a loss of control, where you need to release the sail quickly, simply pull the "hand brake" and the sail clew will release...then bring the spi down by pulling on the sheet, until you have things in control again..
See the drwaings bellow that show how to
rig, the emergency release
line is
line A:
This
is the brand I use HR swivel eye.
