I've thought about it but I think it is most popular with the A cats, where the mainsheet is the only sheet. On an F16, with all the spinnaker sheet, halyard, jib sheet, what ever, to tangle up with, or get hung up on that block in the middle of the tramp, I don't see the advantage.

John Williams has a thread going on the main forum where he explains how he liked it, when he was crewing on his Capricorn. I could maybe see doing this on an F18 if your crew is always going to sheet for you. But on an F16, where you are solo or two up, and if you are not going to have your crew sheeting for you, I think that center tramp block would just be in the way and cause more trouble, more than it would improve your results.

If I had an A cat I would certainly try it.
