I talked to Rick by telephone, and he doesn't understand what you mean by "twisting." He said nothing ever gets twisted up top.

He has used both asymmetrical spinnaker and Hooter on his Taipan 4.9, and for both of them the halyard runs through the same little turning block attached to a hound on the mast. The only difference with the Hooter is that it has the roller-furling system attached to it.

It furls whether the halyard is tight or loose but furls a little easier if the halyard is tight. The halyard, of course, is tightened or loosened depending upon the point of sail and wind conditions.

You would have to explain what you mean about twisting. I think the idea of a furling system is for the furler to do the twisting so nothing else twists.

Maybe you guys are talking about something much more high-tech and complicated. Or maybe you are making it more complicated than it is. We tend to be kind of simplistic.
